import java.awt.event.ActionEvent;
public class Main extends JFrame

   Main(){ //constructor
     JFrame frame = new JFrame("For Mouse Click");

   }

   class ButtonListener implements ActionListener{

int count=0;
      public void actionPerformed(ActionEvent e){
        if(e.getActionCommand() == "Exit") {

System.out.println("Exit button pressed");

System.exit(0)

}
        if(e.getActionCommand() == "New")

{

if(count%2==0) frame.getContentPane().setBackground( Color.BLUE )

else frame.getContentPane().setBackground( Color.GREEN )

count++;

System.out.println("New button pressed");

}
      }
}

   public static void main(String[] args) {
     Main m = new Main();
   }
}
