Question

Rock Paper Scissors Lizard Spock Rock Paper Scissors Lizard Spock is a variation of the common game Rock Paper Scissors that is often used to pass time (or sometimes to make decisions.) The rules of the game are outlined below: • • Scissors cuts Paper Paper covers Rock Rock crushes Lizard Lizard poisons Spock Spock smashes Scissors Scissors decapitates Lizard Lizard eats Paper Paper disproves Spock Spock vaporizes Rock Rock crushes Scissors Write a program that simulates the game of Rock Paper Scissors Lizard Spock! The user should be able to enter Strings for each of their choices (e.g. "Rock" for Rock, "Paper" for Paper etc...). The code should also ensure that the user only enters the strings Rock, Paper or Scissors (and they should be able to enter upper or lower case versions). - Use a while loop with the equalsignoreCase method from the String class for best results! The computer should generate a random value 0, 1, 2, 3, or 4 that would be translated into Rock, Paper, Scissors, Lizard or Spock respectively. o Use a switch statement to store the computer's result as a String. (e.g. if the case matches 0, then the computer's choice should be stored as "Rock" in a String variable.) The program then determines according to the rules above who wins the game. lise nected if else statemente to determine the www.
