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

- A private integer named faceDisplay. The faceDisplay field will hold an integer between 1-6 indicating the side of the dice that is facing up.

The Dice class should have the following methods:

- A no-arg constructor that randomly determines which side is up and sets faceDisplay accordingly.

- A void method named roll() that simulates rolling the dice. When the roll method is called, it randomly determines the number that is shown on the dice, and sets faceDisplay accordingly.

- A method named faceDisplay() that returns the value of the faceUp field.

Write a JAVA program that demonstrates the Dice class. The main program should create an instance of the class and display the side that is initially facing up.
