i try to do button to link to other page call RSA so how to do?
rivate void RSAActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:

}

to link to other page

Can you explain what you mean by this? "link to ..." sounds like the HTML tag <A HREF= and not java.
In the code you posted, the action listener for the JButton: RSA calls the RSAActionPerformed() method when it is pressed.
Is there some processing you want done when the RSA button is pressed?

Example i click on button, it will direct to other page

i click on button, it will direct to other page

What is a page? Are you talking about an html page in a browser?
The GUI for Java programs are displayed in windows created by classes like JFrames.

To have your code do something when a button is clicked, you need to add a listener to the button.
The listener code can then "go to the other page".
I don't know what you mean by "direct to other page". Please explain.
