Our above example for handling mouse events implements MouseListener interface so the class MouseEvent has to implement all the five methods listed below.
implementing MouseListener.

{

}
/*no need to implement all the methods because default implementation given in adapter class*/
Public void mouseClicked(MouseEvent me)
{
setBackground(Color.blue);

}
Public void mouseReleased(MouseEvent me)
