Question

Game rule: paper beats rock; rock beats scissor and scissor beats paper. Paper-0; rock-1; sissor 2 Computer generates random number 0-2 int computerGuess; computerGuess (int) (Math.random ()*3) You are asked to enter value 0-2 Use at least one switch statement DETERMINE WHO WINS OR TIE BECAUSE BOTH PICKED SAME VALUE PRINT-what computer picked, what you picked and who won "Computer picked rock, I picked paper, I won" "Computer picked rock, I picked rock, tie"

Write the code in java. Just a simple code with no While loop. If-else statement is permitted. Thanks.

            switch (playerChoice) {
