How to present a simple alert message in java?

Coming from .NET i am so used calling Alert() in desktop apps. However in this java desktop app, I just want to alert a message saying "thank you for using java" I have to go through this much suffering:

(using a JOptionPane)

Is there an easier way?

I'll be the first to admit Java can be very verbose, but I don't think this is unreasonable:

JOptionPane.showMessageDialog(null, "My Goodness, this is so concise"); 

If you statically import javax.swing.JOptionPane.showMessageDialog using:

import static javax.swing.JOptionPane.showMessageDialog; 

This further reduces to

showMessageDialog(null, "This is even shorter"); 

Assuming you already have a JFrame to call this from:

JOptionPane.showMessageDialog(frame, "thank you for using java"); 

See The Java Tutorials: How to Make Dialogs
See the JavaDoc

If you don't like "verbosity" you can always wrap your code in a short method:

private void msgbox(String s){ JOptionPane.showMessageDialog(null, s); } 

and the usage:

msgbox("don't touch that!"); 

Even without importing swing, you can get the call in one, all be it long, string. Otherwise just use the swing import and simple call:

JOptionPane.showMessageDialog(null, "Thank you for using Java", "Yay, java", JOptionPane.PLAIN_MESSAGE); 

Easy enough.

Call "setWarningMsg()" Method and pass the text that you want to show.

exm:- setWarningMsg("thank you for using java"); public static void setWarningMsg(String text){ Toolkit.getDefaultToolkit().beep(); JOptionPane optionPane = new JOptionPane(text,JOptionPane.WARNING_MESSAGE); JDialog dialog = optionPane.createDialog("Warning!"); dialog.setAlwaysOnTop(true); dialog.setVisible(true); } 

Or Just use

JOptionPane optionPane = new JOptionPane("thank you for using java",JOptionPane.WARNING_MESSAGE); JDialog dialog = optionPane.createDialog("Warning!"); dialog.setAlwaysOnTop(true); // to show top of all other application dialog.setVisible(true); // to visible the dialog 

You can use JOptionPane. (WARNING_MESSAGE or INFORMATION_MESSAGE or ERROR_MESSAGE)

Can use this code simply like javascript:

void alert(String str){ JOptionPane.showMessageDialog(null, str); }
