CoinFlipperPanel.java

This Java program combines a GUI and the Coin object we studied in Chapter 5. Write a GUI program that has a Coin object as one of its instance variables. When a button is pushed, the Coin is flipped, and its heads/tails result is used to update the GUI. The GUI has the following widgets:

a JLabel called "Heads", and a JTextField that contains the number of times the coin is Heads.

a JLabel called "Tails", and a JTextField that contains the number of times the coin is Tails.

a JButton called "Flip". When the user clicks the Flip button, the coin is flipped one time, and the Heads or Tails JTextField is updated as appropriate.

The GUI initially displays 0 as the value for both Heads and Tails.
