WRITE IN JAVA. Write an applet that displays a 4x4 grid(16 square). When the user clicks on square in the grid, the applet should draw a filled circle on it. If the square already has a circle, clicking on it should disappear.

All of this needs to be in one class.

Use the MouseListener

Also, write method mousePressed to update the user mouse clicks.

Use repaint method as well

ps, seen different answers on here, so please do not use previous answers.. old solutions do not work.
