You are used to defining derived classes of the Swing class JFrame. You can

also define derived classes of other Swing classes. Define a derived class of

the class JPanel that is called PinkJPanel. An object of the class PinkJPanel

can be used just as we used objects of the class JPanel, but an object of the

class PinkJPanel is pink in color (unless you explicitly change its color).

The class PinkJPanel will have only one constructor—namely, the

no-argument constructor. (Hint: This is very easy.)
