coin class:

public abstract class Coin {

protected String heads;

protected String tails;

public Coin(String heads, String tails) {

this.heads = heads;

this.tails = tails;

}

public abstract String flipCoin();

}

Make a class called TrickCoin that extends the Coin class. This class should have a static third String in the data field called edge. Overwrite the flipCoin method to return one of the three strings based on the probabilities:

Heads - 45%

Tails - 45%

Edge - 10%
