Java stop further processing

Azamshareef

Dear All,

I am new to Java, please do let me know how to stop further processing ?

If user enter a value <0 in JTextField, i want to show JOptionPane.message until user enter value>0. And this has to be done without exiting(System.exit(0)) the program. Please do comments with some sample code.

***Moderator action (Timo): moved from   to ***

You make a "flagged exit", using a "break" if you are in a looping structure.

The loop is simple for a java novice, but would be visually noticeable because of bringing up/bringing down the dialog.

There is an example in the Java tutorial () of a JOptionPane that stays open until the user's input is correct: https://docs.oracle.com/javase/tutorial/uiswing/components/dialog.html#stayup
