17. Coin Toss Simulator Write a class named Coin. The Coin class should have the following field: • A String named sideUp. The sideUp field will hold either "heads" ing the side of the coin that is facing up. or "tails" indicat- 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 that 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 that returns the value of the sideUp field. Write a program that demonstrates the Coin class. The program should create an instance of the class and display the side that is initially facing up. Then, use a loop to toss the coin 20 tímes. Each time the coin is tossed, display the side that is facing up. The program should keep count of the number of times heads is facing up and the number of times tails is facing up, and display those values after the loop finishes.

ma cass named RoulettePocket. The class's constructor should accept a pocket num-
wThe class should have a method named getPocketColor that returns the pocket's color,
as a string.
Demonstrate the class in a program that asks the user to enter a pocket number, and displays
berher the pocket is green, red, or black. The program should display an error message if
the user enters a number that is outside the range of 0 through 36.

Trite 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" indicat-
ing 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 that 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 that returns the value of the sideUp field.
Write a program that demonstrates the Coin class. The program should create an instance
of the class and display the side that is initially facing up. Then, use a loop to toss the coin
20 times. Each time the coin is tossed, display the side that is facing up. The program should
keep count of the number of times heads is facing up and the number of times tails is facing
up, and display those values after the loop finishes.
