I want to install Oracle's JRE and to update to the latest version with the Software Updater when they released. Is there a Ubuntu package that is provided by Canonical or Oracle?
Before release Java 7, I followed this way to install Java 6.
But it doesn't work for Java 7. There is no package sun-java7-xxx. How can you install Java 7?

There is a similar answer on how to install JRE 7.
Install Java JDK
The manual way
Download the 32-bit or 64-bit Linux "compressed binary file" - it has a ".tar.gz" file extension.
Uncompress it
tar -xvf jdk-8-linux-i586.tar.gz(32-bit)tar -xvf jdk-8-linux-x64.tar.gz(64-bit)The JDK 8 package is extracted into
./jdk1.8.0directory. N.B.: Check carefully this folder name since Oracle seem to change this occasionally with each update.Now move the JDK 8 directory to
/usr/libsudo mkdir -p /usr/lib/jvm sudo mv ./jdk1.8.0 /usr/lib/jvm/
Now run
sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.8.0/bin/java" 1 sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.8.0/bin/javac" 1 sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/lib/jvm/jdk1.8.0/bin/javaws" 1
This will assign Oracle JDK a priority of 1, which means that installing other JDKs will replace it as the default. Be sure to use a higher priority if you want Oracle JDK to remain the default.
Correct the file ownership and the permissions of the executables:
sudo chmod a+x /usr/bin/java sudo chmod a+x /usr/bin/javac sudo chmod a+x /usr/bin/javaws sudo chown -R root:root /usr/lib/jvm/jdk1.8.0
N.B.: Remember - Java JDK has many more executables that you can similarly install as above.
java,javac,javawsare probably the most frequently required. This answer lists the other executables available.Run
sudo update-alternatives --config java
You will see output similar to the one below - choose the number of jdk1.8.0 - for example
3in this list (unless you have have never installed Java installed in your computer in which case a sentence saying "There is nothing to configure" will appear):$ sudo update-alternatives --config java There are 3 choices for the alternative java (providing /usr/bin/java). Selection Path Priority Status ------------------------------------------------------------ 0 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1071 auto mode 1 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1071 manual mode * 2 /usr/lib/jvm/jdk1.7.0/bin/java 1 manual mode 3 /usr/lib/jvm/jdk1.8.0/bin/java 1 manual mode Press enter to keep the current choice[*], or type selection number: 3 update-alternatives: using /usr/lib/jvm/jdk1.8.0/bin/java to provide /usr/bin/java (java) in manual modeRepeat the above for:
sudo update-alternatives --config javac sudo update-alternatives --config javaws
Note for NetBeans users!
You need to set the new JDK as default editing the configuration file.
If you want to enable the Mozilla Firefox plugin:
32 bit: ln -s /usr/lib/jvm/jdk1.8.0/jre/lib/i386/libnpjp2.so ~/.mozilla/plugins/ 64 bit: ln -s /usr/lib/jvm/jdk1.8.0/jre/lib/amd64/libnpjp2.so ~/.mozilla/plugins/ N.B.: You can link the plugin (libnpjp2.so) to /usr/lib/firefox/plugins/ for a system-wide installation (/usr/lib/firefox-addons/plugins from 15.04 onwards). For Ubuntu 13.10, the path to the plugin directory is /usr/lib/firefox/browser/plugins/.
Depending on your configuration, you might need to update the apparmor profile for Firefox (or other browsers) in /etc/apparmor.d/abstractions/ubuntu-browsers.d/java:
# Replace the two lines: # /usr/lib/jvm/java-*-sun-1.*/jre/bin/java{,_vm} cx -> browser_java, # /usr/lib/jvm/java-*-sun-1.*/jre/lib/*/libnp*.so cx -> browser_java, # with those (or adapt to your new jdk folder name) /usr/lib/jvm/jdk*/jre/bin/java{,_vm} cx -> browser_java, /usr/lib/jvm/jdk*/jre/lib/*/libnp*.so cx -> browser_java, Then restart apparmor:
sudo /etc/init.d/apparmor restart The easy way (Obsolete)
Note: WebUpd8 team's PPA has been discontinued with effective from April 16, 2019. Thus this PPA doesn't have any Java files. More information can be found on PPA's page on Launchpad. Hence this method no longer works and exists because of hostorical reasons.
The easiest way to install the JDK 7 is to do it with the Web Up8 Oracle Java OOS. However, it is believed that this PPA is sometimes out of date. Also note the dangers of using a PPA.
This installs JDK 7 (which includes Java JDK, JRE and the Java browser plugin):
sudo apt-get install python-software-properties sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java7-installer # or if you want JDK 8: # sudo apt-get install oracle-java8-installer # these commands install Oracle JDK7/8 and set them as default VMs automatically: # sudo apt-get install oracle-java7-set-default # sudo apt-get install oracle-java8-set-default N.B.: Before someone screams this is against the Oracle redistribution license - the PPA does not actually have Java in the personal repository. Instead, the PPA directly downloads from Oracle and installs it.
The Script way
If you're on a fresh installation of Ubuntu with no previous Java installations, this script automates the process outlined above if you don't want to type all that into a console. Remember, you still need to download Java from Oracle's website -- Oracle's links are not wget friendly.
Before using this make sure that this script is in the same directory as the .tar.gz file extension that you downloaded and there are no files that start with jdk-7 in the same folder. If there are, please move them out of the folder temporarily. Remember to make the script executable (chmod +x <script's file>).
#!/bin/sh tar -xvf jdk-7* sudo mkdir /usr/lib/jvm sudo mv ./jdk1.7* /usr/lib/jvm/jdk1.7.0 sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.7.0/bin/java" 1 sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.7.0/bin/javac" 1 sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/lib/jvm/jdk1.7.0/bin/javaws" 1 sudo chmod a+x /usr/bin/java sudo chmod a+x /usr/bin/javac sudo chmod a+x /usr/bin/javaws If you want to install the plugin for Firefox then add this to the end of the script:
mkdir ~/.mozilla/plugins ln -s /usr/lib/jvm/jdk1.7.0/jre/lib/amd64/libnpjp2.so ~/.mozilla/plugins/ sudo /etc/init.d/apparmor restart Check if installation was successful
You can check if the installation succeeded with the following command:
java -version You should see something like
java version "1.8.0" Java(TM) SE Runtime Environment (build 1.8.0-b132) Java HotSpot(TM) 64-Bit Server VM (build 25.0-b70, mixed mode) You can check if the JRE Mozilla plugin has been successful by using the official oracle website.

16There is a similar answer on how to install JDK 8
Install the JRE
Download the 32-bit or 64-bit Linux "compressed binary file" - it has a ".tar.gz" file extension and uncompress it
tar -xvf jre-7-linux-i586.tar.gz The JRE 7 package is extracted into ./jre1.7.0 directory. Now move the JRE 7 directory to /usr/lib:
sudo mv ./jre1.7.0* /usr/lib/jvm/jre1.7.0 Afterwards, run the following to get a list of currently installed Java alternatives.
sudo update-alternatives --config java You will get output as:
There are 2 choices for the alternative java (providing /usr/bin/java). Selection Path Priority Status ———————————————————— * 0 /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 auto mode 1 /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 manual mode 2 /usr/lib/jvm/java-6-sun/jre/bin/java 63 manual mode Press enter to keep the current choice[*], or type selection number: Remember the last number and press enter to exit this utility i.e. in this example remember the number 2.
If only one alternative is shown then remember the number 0.
sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jre1.7.0/bin/java 3 This will add your new JRE 7 installation into the alternatives list i.e. use the remembered number + 1, that is, 3 in the example above. Now configure Java to use the Oracle Java JRE:
sudo update-alternatives --config java You will see output similar one below - choose the number of jre1.7.0, that is, 3:
There are 3 choices for the alternative java (providing /usr/bin/java). Selection Path Priority Status ———————————————————— * 0 /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 auto mode 1 /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 manual mode 2 /usr/lib/jvm/java-6-sun/jre/bin/java 63 manual mode 3 /usr/lib/jvm/jre1.7.0/jre/bin/java 3 manual mode Press enter to keep the current choice[*], or type selection number: 3 update-alternatives: using /usr/lib/jvm/jre1.7.0/jre/bin/java to provide /usr/bin/java (java) in manual mode. N.B.: If there was no previous Java installation then the new JRE will be the default and you will not see the above.
Check the version of you new JRE 7 installation:
java -version It should produce
java version “1.7.0” Java(TM) SE Runtime Environment (build 1.7.0-b147) Java HotSpot(TM) Client VM (build 21.0-b17, mixed mode) Install the Firefox/Chrome plugin
In a terminal:
mkdir ~/.mozilla/plugins Remove the IcedTea plugin, if it has been installed.
sudo apt-get remove icedtea6-plugin Remove a former version of the Java plugin (may or may not be present):
rm ~/.mozilla/plugins/libnpjp2.so Now you can install the plugin, by creating a symbolic link (you tell Firefox, where the plugin is located). For 32-bit Java use
ln -s /usr/lib/jvm/jre1.7.0/lib/i386/libnpjp2.so ~/.mozilla/plugins/ For 64-bit Java use
ln -s /usr/lib/jvm/jre1.7.0/lib/amd64/libnpjp2.so ~/.mozilla/plugins/ Confirm that the JRE has been successful by using the official oracle website.
15Here is a tested and working solution for installing Oracle JDK 7 and all its files so "javac" and everything else works: How To Install Oracle Java 7 (JDK) In Ubuntu
Here are the commands (just for convenience):
- Download the latest Oracle JDK 7 from here.
- Extract the downloaded Oracle Java JDK archive in your home folder - a new folder called "jdk1.7.0_03" (for Java JDK7 update 3) should be created. Rename it to "java-7-oracle" and move it to /usr/lib/jvm using the following commands:
cd sudo mkdir -p /usr/lib/jvm/ #just in case sudo mv java-7-oracle/ /usr/lib/jvm/3. Install Update Java package created by Bruce Ingalls (packages available for Ubuntu 11.10, 11.04, 10.10 and 10.04):
sudo add-apt-repository ppa:nilarimogard/webupd8 sudo apt-get update sudo apt-get install update-java4. Now run the following command in a terminal to install Oracle Java JDK:
sudo update-java
After a few minutes, Oracle Java JDK should be successfully installed on your Ubuntu machine. You can check out the version by running these commands in a terminal:
java -version javac -version

sudo apt-get install python-software-properties sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-jdk7-installer This is how I installed it in Oneiric just now. It will be a rather lengthy answer, but it worked for me.
Download latest Java SDK 1.7.0 from Oracle. Then extract it to /usr/lib/jvm:
cd /usr/lib/jvm/ sudo tar -xvzf ~/jdk-7-linux-x64.tar.gz sudo mv jdk1.7.0 java-7-oracle sudo ln -s java-7-oracle java-1.7.0-oracle After that I created .java-1.7.0-oracle.jinfo file in /usr/lib/jvm with the following contents:

sudo apt-get install oracle-java6-installer sudo apt-get install oracle-java7-installer sudo apt-get install oracle-java8-installer sudo apt-get install oracle-java9-installerWhen the respective Java installer script is loaded and then it downloads and installs the proprietary Java packages, you can also enter the following command to check the result of the installation:
java -version
You should then get a terminal output (for java8 stable version) like this:
java version "1.8.0_72" Java(TM) SE Runtime Environment (build 1.8.0_72-b15) Java HotSpot(TM) 64-Bit Server VM (build 25.72-b15, mixed mode) NB: These packages provide Oracle Java JDK, which includes Java JDK, JRE and the Java browser plugin. And the webupd8team/java PPA contains only these installers, which simply connect to Oracle Java download site and install the latest JDK.
4Note: WebUpd8 team's PPA has been discontinued with effective from April 16, 2019. Thus this PPA doesn't have any Java files. More information can be found on PPA's page on Launchpad. Hence this method no longer works and exists because of historical reasons.
I appreciate all the previous answers. I want to add this answer to simplify things which is done by to make installation in 2-5 minutes.
This installation includes:
sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java7-installer That's all!! Now to check the Java version
java -version The output will be like
java version "1.7.0_25" Java(TM) SE Runtime Environment (build 1.7.0_25-b15) Java HotSpot(TM) Server VM (build 23.25-b01, mixed mode There may come a new version, and then you can simply update it with this command:
sudo update-java-alternatives -s java-7-oracle Setting up environment variables
sudo apt-get install oracle-java7-set-default For more, check out Install Oracle Java 7 in Ubuntu via PPA Repository.
2This solution will give you clean built packages just as they used to ship with Ubuntu before Oracle came around.
The answer
First the answer, then the explanation. Open a terminal and copy and paste the following, line by line.
wget -O oab-java.sh chmod +x oab-java.sh sudo ./oab-java.sh This will build the official sun-java6-* packages and make them available in the software-center. If you also want oracle-java7-* packages, run the script like this:
sudo ./oab-java.sh -7 Now you can install the packages with your preferred package manager.
The explanation
When Oracle changed the distribution license for Java, Linux distributions weren't allowed to update the official packages anymore. Github user rraptorr took the Debian script that was used to build the packages until then, and modified it to work with the updated downloads from Oracle. He now provides packging scripts for SUN Java6 and Oracle Java7.
The oab.java.sh script is just a wrapper that automatically downloads the current version, creates the packages and adds them to a local repository.
Further notes
Packages created and installed using this method, will not receive updates automatically - only when you rerun the script. You can circumvent this by creating a cronjob that runs this script on a regular basis. The savest way to do this is using anacron by putting the script in /etc/cron.daily.
wget -O /root/oab-java.sh chmod +x /root/oab-java.sh ln -s /root/oab-java.sh /etc/ Now your official Java packages will always be up-to-date.
6This worked for my development needs of being able to run/compile 1.6 or 1.7. Previously I was just running 1.6 from a Ubuntu apt package.
- Download 1.7 gzip.
- Extract to folder
Update JAVA_HOME and PATH in bash file
JAVA_HOME=/opt/java/jdk1.7.0_25 export JAVA_HOME PATH=$JAVA_HOME/bin:$PATH export PATH
On AMD64 you need modify a little the command to create the symbolic link:
ln -s /usr/lib/jvm/jre1.7.0/lib/amd64/libnpjp2.so ~/.mozilla/plugins/ only change the i386 to amd64.
To make it available for all users :
sudo ln -s /usr/lib/jvm/jre1.7.0/lib/i386/libnpjp2.so /usr/lib/mozilla/plugins/ for x86_64 :
sudo ln -s /usr/lib/jvm/jre1.7.0/lib/amd64/libnpjp2.so /usr/lib/mozilla/plugins/ Get the JDK from Oracle/Sun; download the Java JDK at:
Please download or move the downloaded file to your home directory, ~, for ease.
Note:
Don't worry about what JDK to download for JEE.
Please skip copying the Prompt " user@host:~$ ".
Hit enter after each command.
Run in a terminal..
user@host:~$ sudo mkdir -p /usr/lib/jvm/ user@host:~$ sudo mv jdk-7u4-linux-i586.tar.gz /usr/lib/jvm/ user@host:~$ cd /usr/lib/jvm/ user@host:~$ sudo tar zxvf jdk-7u4-linux-i586.tar.gz Now enable Java (by running individually):
user@host:~$ sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.7.0_04/bin/java" 1 user@host:~$ sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.7.0_04/bin/javac" 1 user@host:~$ sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/lib/jvm/jdk1.7.0_04/bin/javaws" 1 Close all browsers.
Create a Mozilla plugins folder in your home directory:
user@host:~$ mkdir ~/.mozilla/plugins/ Create a symbolic link to your Mozilla plugins folder. For 64-bit systems, replace ‘i386’ with ‘amd64’:
user@host:~$ ln -s /usr/lib/jvm/jdk1.7.0/jre/lib/i386/libnpjp2.so ~/.mozilla/plugins/ Testing:
user@host:~$ java -version Output:
java version "1.7.0_04" Java(TM) SE Runtime Environment (build 1.7.0_04-b20) Java HotSpot(TM) Server VM (build 23.0-b21, mixed mode) Testing:
user@host:~$ javac -version Output:
javac 1.7.0_04 I propose one way to make easier the installation of Oracle's Java 7.
Since Ubuntu does not provides the Oracle's Java 7 packages, I'm providing a collection of Ubuntu packages on my own package repository.
The packages are fully integrated in the Ubuntu way to support Java. You will be able to select the Oracle's Java 7 alternative with the standard tools: update-alternative or update-java-alternative.
The main page of my contribution is:
To obtain the packages, you only need to add my package repository into your system configuration. The process is explained in
Stéphane.
2The easiest way is just downloading java 7 with Netbeans here -
Note: WebUpd8 team's PPA has been discontinued with effective from April 16, 2019. Thus this PPA doesn't have any Java files. More information can be found on PPA's page on Launchpad. Hence this method no longer works and exists because of historical reasons.
For those who live in Syria, Cuba, Libya, Korea or any country where Oracle is banning its services, this is a working way to install Oracle JDK 8.
- Using a PROXY, go to this link and accept the terms then download the tar.gz suitable to your system (32 or 64 bit).
- Move that tarball to the Downloads directory in your home folder.
- run this script as sudo:
if [[ $UID != 0 ]]; then echo "This script neeeds to be run with sudo, like this:" echo -e "\n sudo $0 $*\n" exit 1 fi apt-get install python-software-properties add-apt-repository ppa:webupd8team/java apt-get update apt-get install oracle-java8-installer if [ ! -f $HOME/Downloads/jdk-8u5-linux-*.tar.gz ]; then echo "The JDK tar.gz file was not found in $HOME/Downloads. please download it, put it in $HOME/Downloads and run again." exit 1 fi cp ~/Downloads/jdk-8u5-linux-*.tar.gz /var/cache/oracle-jdk8-installer/ apt-get install oracle-java8-installer apt-get install oracle-java8-set-default java -version For me it's a little bit different. For Ubuntu 12.04 LTS Precise (Desktop):
Download
jre-*.tar.gztar -zxvf jre-*.tar.gzmkdir /usr/lib/jvm/mv jre* /usr/lib/jvm/ln -s /usr/lib/jvm/jre*/bin/java /usr/bin/
That's all.
To make sure it's correct:
java -version If you want to add plug in for Firefox or Chrome:
mkdir ~/.mozilla/pluginsln -s /usr/lib/jvm/jre*/lib/i386/libnpjp2.so ~/.mozilla/plugins/
Special Note: If you have a fresh 64 bit install, you may experience the following error when running java -version
-bash: ./java: No such file or directory This is caused by a dependency on the libc6-i386 package which is not included by default in 64 bit Ubuntu Desktop 12.04 LTS. To install this package, run: sudo apt-get install libc6-i386
Here's a bash script that could help in setting up the java alternatives:
#!/bin/bash BIN_HOME="/usr/bin" JVM_BIN_HOME="/usr/lib/jvm/jdk1.7.0_21/bin" UPDATE_CMD="update-alternatives" UPDATE_OPT="--install" UPDATE_DEFAULT_PRIORITY=10 echo "Installing alternatives for Oracle JDK." #echo "JAVA_BIN_HOME=$JAVA_BIN_HOME" #echo "BIN_HOM=$BIN_HOME" echo "All cmds in \"$JVM_BIN_HOME\" will be installed in \"$BIN_HOME\" with \"$UPDATE_CMD\"" echo # # Calls update-alternatives. # Param 1 is the java cmd name and optionally param 2 is the priority # See 'man update-alternatives' for more information. # function update_alt() { if [ -z "$2" -o "${2}xxx" = "xxx" ]; then echo "using default priority: $UPDATE_DEFAULT_PRIORITY" PRIORITY=$UPDATE_DEFAULT_PRIORITY else PRIORITY=$2 fi EXEC="$UPDATE_CMD $UPDATE_OPT $BIN_HOME/$1 $1 $JVM_BIN_HOME/$1 $PRIORITY" echo $EXEC $EXEC return 0 } for bin in $JVM_BIN_HOME/* do if [ -x $bin ]; then cmd=$(basename $bin) if [ -x $BIN_HOME/$cmd ]; then echo "notice: alternative already installed, \"$cmd\"" continue # Skip installation of alternative. fi echo "install alternative: $cmd" update_alt $cmd if [ ! -x $BIN_HOME/$cmd ]; then echo "error: failed to install alternative, \"$cmd\"" exit 1 fi fi done exit 0 Straightforward Solution
Rather than downloading the .tar.gz package I recommend you download the .rpm package. Then run:
sudo apt-get install alien dpkg-dev debhelper build-essential sudo alien --scripts jdk-7u-linux-.rpm where I believe the current <build> is 21 and the <version> depends on your system architecture.
The first will install alien, a application for converting .rpm to .deb. The second command then runs alien on jdk package. This should run for a minute or two and produce a file labelled:
jdk-7u<build>-linux-<version>.deb
This package may then be installed by running:
sudo dpkg -i jdk-7u<build>-linux-<version>.deb This is how I successfully installed it on my machine.
1I think that the best method has been already posted but I had some problem with this : namely I remove java 'manually' from update-alternatives and then I have tried to do this
update-alternatives --install "/usr/bin/java/" "java" "/usr/lib/jvm/jre1.7.0_05/bin/java" 1
but I kept on getting this error
update-alternatives: using /usr/lib/jvm/jre1.7.0_05/bin/java to provide /usr/bin/java/ (java) in auto mode. update-alternatives: error: unable to make /usr/bin/java/.dpkg-tmp a symlink to /etc/alternatives/java: No such file or directory
But fortunately I have encountered a great tutorial on this site : and it worked just fine :)
1For installing the 32-bit variant of Java on 64-bit Ubuntu:
Open up a terminal window ( Ctrl + Alt + T is the quickest method if you're not aware) and type in the following to install:
sudo add-apt-repository "deb precise-arakhne universe" wget -O - | sudo apt-key add - apt-get install ia32-oracle-java7-jre The best method that I can deliver if you want to install Java 6 under Ubuntu 12.04 LTS (Precise Pangolin) is:
sudo apt-get purge sun-java You need to do that if you want the Mozilla plugin to work without conflict with Java 7 for instance.
mkdir ~/src cd ~/src git clone cd ~/src/oab-java6 sudo ./oab-java.sh Then when it's finished, install Java:
sudo apt-get install sun-java6-plugin sun-java6-jre sun-java6-bin sun-java6-jdk You can follow the installation process with:
tail -f ~/src/oab-java6/oab-java.sh.log Explanation: the same as in an answer to How can I install Sun/Oracle's proprietary Java JDK 6/7/8 or JRE?.
Ref: Installing Java6 JDK on Ubuntu 12.04
To me the Debian way (sic) would be to create your own package.
You install java-package
sudo apt-get install java-package You download the Oracle tar.gz archive.
You create your deb package
fakeroot make-jpkg jdk-7u79-linux-x64.tar.gz An you install it
sudo dpkg -i oracle-java7-jdk_7u79_amd64.deb Download your desired .tar.gz version of JDK for your Ubuntu system from , for example jdk-8u102-linux-x64.tar.gz.
Extract it to anywhere you want in /home directory, for example /home/dante/Programs/Java. Now we have a folder with the name like jdk1.8.0_102 inside /home/dante/Programs/Java.
Add these two lines to your /home/dante/.profile file
export JAVA_HOME=/home/dante/Programs/Java/jdk1.8.0_102 export PATH=$JAVA_HOME/bin:$PATH Restart your system and after reboot you should see your Java version by running java -version in terminal.
I don't know why people have given so much big answers but adding jdk/bin to PATH works just fine:-
Exctract any whereve you want . I like
/optex:-
tar -xvf jdk-9.0.1_linux-x64_bin.tar.gz -C /opt
Add your jdk/bin to PATH as told here in my case this is how my /etc/environment looks:-
$ cat /etc/environment PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/opt/jdk-9.0.1/bin" JAVA_HOME="/opt/jdk-9.0.1/" To install Sun Java 6 on Precise through Trusty, you can use the Preserved Removed Primary/Partner Archive packages PPA.
sudo add-apt-repository ppa:maxb/preserved sudo apt-get update sudo apt-get install sun-java6-jre sudo update-alternatives --config java And then select the desired Java version. You can check what you're now running by:
geek@liv-inspiron:/tmp$ java -version java version "1.6.0_26" Java(TM) SE Runtime Environment (build 1.6.0_26-b03) Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode) Installing Oracle Java (JDK/JRE):
You can automate the task of installing/uninstalling Oracle Java (JDK/JRE) from a downloaded (tar.gz) source with this script: oraji.
Steps:
- Download the tar.gz source of your desired jdk/jre version.
- run
sudo oraji /path/to/the/jdk_or_jre/archive
Uninstall:
run sudo oraji -u and confirm the jdk/jre version to be uninstalled.
OS: Ubuntu 18.04 LTS
I am surprised no one has mentioned conda . Link:
I installed java in one of my conda environments and used the java command without problems.
You can download the latest Oracle JDK 8, then you open a terminal with 'Ctrl + Alt + t' and enter the following commands:
cd /usr/lib/jvm If the /usr/lib/jvm folder does not exist, enter this command will create the directory sudo mkdir /usr/lib/jvm
Then extract the jdk-{version}.tar.gz file in that directory using this command.
sudo tar -xvzf ~/Downloads/jdk-{version}.tar.gz The the following command to open the environment variables file.
sudo vim /etc/environment In the opened file, add the following bin folders to the existing PATH variable.
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/lib/jvm/jdk-{version}/bin:/usr/lib/jvm/jdk-{version}/db/bin:/usr/lib/jvm/jdk-{version}/jre/bin" J2SDKDIR="/usr/lib/jvm/jdk-{version}" J2REDIR="/usr/lib/jvm/jdk-{version}/jre" JAVA_HOME="/usr/lib/jvm/jdk-{version}" DERBY_HOME="/usr/lib/jvm/jdk-{version}/db" Save the changes and close the vim.
Then enter the following commands to inform the system about the Java's location.
sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk-{version}/bin/java" 0 sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk-{version}/bin/javac" 0 sudo update-alternatives --set java /usr/lib/jvm/jdk-{version}/bin/java sudo update-alternatives --set javac /usr/lib/jvm/jdk-{version}/bin/javac To verify the setup enter the following commands and make sure that they print the location of java and javac as you have provided in the previous step.
update-alternatives --list java update-alternatives --list javac Now restart the terminal again and enter following commands.
java -version javac -version If you get the installed Java version as the output, you have successfully installed the Oracle JDK in your system.
