RPSLS Features (Updates):
The user input should be text, not numerical (e.g., \"rock\" not 1). It should also be case-insensitive (see the Sample Run, below).
Suggestion: use the Scanner method nextLine() instead of the Scanner method next() for user input.
Suggestion: to minimize re-write of your existing code, \"translate\" the user input into one of five values (there are three in the original program);
a good way to do this is to define and call a method static int textToNumber(String choice).
After each round, the user is prompted as to whether they want to play again (i.e., yes or no).
Suggestion: only play again if the user enters yes; otherwise, end the game.
Suggestion: use the Scanner method nextLine() instead of the Scanner method next() for user input.
For each round, the user input of choice should be validated as one of the five valid choices; anything else causes the round to be forfeited and prompts the user as to whether they want to play another round.
Suggestion: define a method static boolean isValid(String choice) and call it with the user choice as an if condition.
You will have to add methods for the two new choices that the user can make:
int lizardChoice(int computerChoice)
int SpockChoice(int computerChoice)
As with the original three methods, each of these two new methods returns one of the three named int constants PLAYER1_WINS, PLAYER2_WINS, orDRAW.
You will also have to re-define (expand) the code in the original three methods rockChoice, paperChoice, and scissorsChoice to check whether the computer chose either of the two new choices (i.e., lizard or Spock).

Welcome to the game of Rock Paper Scissors Lizard Spock
Here are the rules:
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
(and as it always has) Rock crushes scissors
Ready? Then let\'s begin!
Player 1, enter your choice ( rock, paper, scissors, lizard, Spock ): rock
OK, you chose rock
Player 2 (computer) chooses rock
It\'s a draw
Play again (yes/no)? yes
Player 1, enter your choice ( rock, paper, scissors, lizard, Spock ): spock
OK, you chose spock
Player 2 (computer) chooses lizard
Lizard poisons Spock; Player 2 wins
Play again (yes/no)? yes
Player 1, enter your choice ( rock, paper, scissors, lizard, Spock ): banana <--- invalid input
Invalid choice \"banana\"; try again.
Player 1, enter your choice ( rock, paper, scissors, lizard, Spock ): Paper
OK, you chose paper
Player 2 (computer) chooses scissors
Scissors cut paper; Player 2 wins
Play again (yes/no)? yes
Player 1, enter your choice ( rock, paper, scissors, lizard, spock ): <--- invalid input (empty string)
Invalid choice \"\"; try again.
Player 1, enter your choice ( rock, paper, scissors, lizard, Spock ): SCISSORS
OK, you chose scissors
Player 2 (computer) chooses paper
Scissors cut paper; Player 1 wins
Play again (yes/no)? yes
Player 1, enter your choice ( rock, paper, scissors, lizard, Spock ): lIZARD
OK, you chose lizard
Player 2 (computer) chooses scissors
Scissors decaptiate lizard; Player 2 wins
Play again (yes/no)? no
