public class Coin
extends javax.swing.JComponent

This class defines a coin with specified colors, value, and probability of heads. The state of the coin can be tossed or not tossed. If tossed, the coin is drawn with a color and label that depend on the outcome (heads or tails). If not tossed, the coin is shown as an outline in the background color.
