Rock Paper Scissors!

10/6/2017 at 11:55 PM

Objective:

Write a program that simulates a game of rock, paper, scissors between a human and the computer in best 2 out of 3 rounds.

Requirements:

• The player can enter either “rock”, “paper”, or “scissors”.
• If the player enters anything other than that the computer automatically gets a point
• The computer randomly selects one of the gestures
• Use the Random type to make this easier
• Also make sure you import java.util.Random
• You can use randomly selected integers to represent the gestures
• For each combination either the computer scores a point, the player scores a point, or they score neither on draws.
• Rock vs Paper = Paper wins
• Paper vs Scissors = Scissors wins
• Scissors vs Rock = Rock wins
• After 3 rounds the winner or a tie is declared
• The player is then asked whether or not they want to play again, and if they do the whole process starts over.
