I have four JTextFields where user is allowed to enter only numbers.
Question is how do I do this?

Jump to PostYou could use the keypressed event handler

or wait till the user enters the entire lot then parse it at the end returning either a success or fail message.

Jump to PostI think that limiting user input is always good.
How about the JSpinner class. That should allow the user to input a large range of numbers (that you specify in the constructor).
