Suppose, we have added two jFrame and want to open another jframe through existing jframe’s button’s click event. Suppose, First is ‘TestJFrame’ and second is ‘Second_Jframe’. Both contains same packages. So the point is, we want to open it through button’s press and back to first through second jframe’s button press.
How do you link two frames in Java?
