To describe the objects ROCK , PAPER , and SCISSORS , we define the following enum
type:

public enum RockPaperScissors
{

ROCK ("Rock crushes scissors."),
PAPER ("Paper covers rock."),
SCISSORS ("Scissors cuts paper.");

private String mgs;

private RockPaperScissors()
{

mgs = "";

}

private RockPaperScissors(String str)
{

mgs = str;

}

public String getMessage()
{

return mgs;

}

}

It is clear that you need the following variables in the method main :

Variables

main )

int gameCount; //to count the number of

//games played

int winCount1; //to count the number of

//games won by player 1

int winCount2; //to count the number of

//games won by player 2

int gameWinner;
char response; //to get the user's response

//to play the game

char selection1;
char selection2;

RockPaperScissors play1; //player1's selection

RockPaperScissors play2; //player2's selection

This program is divided into six methods, which the following sections describe in
detail.
