Hi, I have some question and hope that someone can help me to solve it.

When I click one button in JFrame form, then can the JFrame form hide and another JFrame form will appear?

Hope can provide some sample code on how to do it?

Thanks

When you click the button you need to hide the current JFrame and call the other.

class JFrame_A extends JFrame {
....
....

public void methodBuitonClicked( ...... ) {
  JFrame_B frameB = new JFrame_B();
  this.setVisisble(false);
  frameB.setVisisble(true);
}
.....
.....
}

If you want from the frameB to go back to A you need to pass the A as an argument at the B frame: JFrame_B frameB = new JFrame_B(this); Of course you will need to have the appropriate attribute at the JFrame_B.
Then set the B frame visible false and the frame A that you passed as argument to true
