Weekend Task - Coin Toss Game - Tossing Coins for a Dollar

[akash-coded]

Write a class named Coin. The Coin class should have the following field:

• A String named sideUp. The sideUp field will hold either “heads” or “tails” indicating the side of the coin that is facing up.

The Coin class should have the following methods:

• A no-arg constructor that randomly determines the side of the coin that is facing up (“heads” or “tails”) and initializes the sideUp field accordingly.
• A void method named toss simulates the tossing of the coin. When the toss method is called, it randomly determines the side of the coin that is facing up (“heads” or “tails”) and sets the sideUp field accordingly.
• A method named getSideUp returns the value of the sideUp field.

Create a game program using the coin class. The program should have three instances of the coin class: one representing a quarter, one representing a dime, and one representing a nickel.

When the game begins, your starting balance is $0. During each round of the game, the program will toss the simulated coins. When a coin is tossed, the value of the coin is added to your balance if it lands heads-up. For example, if the quarter lands heads-up, 25 cents is added to your balance. Nothing is added to your balance for coins that land tails up. The game is over when your balance reaches one dollar or more. If your balance is exactly one dollar, you win the game. You will lose if your balance exceeds one dollar.
