********Draw the UML Class diagram for this project***********

Write one interface and three classes which will make a rock paper scissors game. First download the driver.

The interface named RPSPlayerInterface will have the following methods

public int getPoints()

public String getGesture()

public void setPoints(int aPoints)

public void setGesture(String aGesture)

public void chooseGesture()

The next class RPSPlayer implements this interface

It has an instance variable gesture which is a string that corresponds to rock, paper, or scissors

It has another instance variable points that keeps track of how many times the player has won

Create only a default constructor that sets the gesture to none and points to 0

Create the accessors and mutators for the instance varaibles

The mutator for setGesture should make sure it is either rock, paper, or scissors. If it is not then tell the user that was a wrong choice and set gesture to none

Write the chooseGesture method

In this case just set the instance variable gesture to none

Next write the class RPSHumanPlayer which inherits from RPSPlayer

It has an instance variable keyboard which is of type Scanner

Make sure to import java.util.Scanner

Create a default constructor

Calls the parents default constructor

Sets up the keyboard to System.in

Override the method chooseGesture

Call the parents setGesture method and pass the string gotten from the Scanner keyboard.

You do not have to prompt the user.

Next write the class RPSComputerPlayer which also inherits from RPSPlayer

It has an instance variable rand which is of type Random

Make sure to import java.util.Random

Create a default constructor

Calls the parents default constructor

Constructs the rand variable

Override the method chooseGesture

Using the random variable it should randomly select a number

Correspond the number to a string which will either rock, paper, or scissors

For instance if rand equals 0 then it is a rock, else if 1 then paper, else if 2 then scissors

Use the parents setGesture to then assign the randomly picked gesture
