Que)Create an Applet which displays a message in the center of the screen. The message
indicates the events taking place on the applet window. Handle events like mouse click,
mouse moved, mouse dragged, mouse pressed, and key pressed. The message should
update each time an event occurs. The message should give details of the event such as
which mouse button was pressed, which key is pressed etc. (Hint: Use repaint(),
KeyListener, MouseListener, MouseEvent method getButton, KeyEvent methods
getKeyChar)
