I just start learning java using netbean. I am now have one jFrame containing a jPanel1, and one jPanel2 class.
I want to add jPanel2 into jPanel1 in jFrame in certain condition. So i've tried
if(split){
jPanel2 = new jPanel2();
jPanel1.add(jPanel2);
Panel1.setVisible(true);
}

I am working on a 15 puzzle.
I need to change the JPanel in the JFrame for a new game.
The reason is that some games have 16 buttons while others have 9 or 25. Sometimes the buttons have a number, but sometimes they have pieces of a picture.
I would like to set up my JPanel, then set it into the JFrame.
The only way that I have been able to achieve this so far is to create a new JFrame, but that outputs a new window.
Is it possible to change the JPanel in the JFrame in java?

I was wondering if it was possible to disable all other action when a JFrame is opened in Java.
Just like this?
Is there easy code for this?
This has been asked many times and the answer is always the same: use a modal JDialog or JOptionPane (which is a version of a modal JDialog), not another JFrame.
For example, please check out mKorbel's answer here.
