Answer Posted / ayyappan raja

use, Static method of JFrame called setDefaultCloseoperation
()and pass the arguments as ONE of follows :
Arguments Description

1.JFrame.EXIT_ON_CLOSE Exits the application.
2. JFrame_HIDE_ON_CLOSE closes the clicked frame
window,not the application.
For example,
class Frame1 extends JFrame{
public Frame1(){
super(" FrameTest ");
setSize(400,340);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
}
}
