How to disable main JFrame when open new JFrame

Question

Example now I have a main frame contains jtable display all the customer information, and there was a create button to open up a new JFrame that allow user to create new cus

Answer 1

just use firstFrame.setVisible(false) on the first frame. This will make it hidden..

if you want a more general approach you could have a reference to the current displayed frame somewhere and change it when a new frame requests to be shown

JFrame currentFrame;

void showRequest(JFrame frame)
{
  currentFrame.setVisible(false);
  currentFrame = frame;
  currentFrame.setVisible(true);
}
