HOW TO MAKE ROCK PAPER SCISSOR GAME IN JAVA

  What is Rock Paper Scissor game?

Rock paper scissor game is hand game played between two players ,in each player at the same time forms one of three shapes.

Rock Paper Scissor game in java 

When we want to rock paper scissor game with computer what we do for this 

we make a computer program with the help of java.

LETS START CODING

We use while loop to play  game five times after that calculate the points of both user and computer then print the winner and there points.

In this game we take 0 for stone, 1 for paper, 2 for scissor.

import java.util.Random

We have to import random module to generate the computer choice. simply ,we have to write import java.util.Random; to import random module.

Taking user input 

For taking input from the user we have to import import java.util.Scanner;

After that we have to write System.out.println("Enter your play:");

            Scanner sc = new Scanner(System.in);

            int userplay = sc.nextInt();

MAKING  COMPUTER CHOICE 

For computer choice we have to write  Random r=new Random();

            int computerplay = r.nextInt(3);

GAME CONDITION 

For game condition and determine winner we have to use IF ,ELSE condition .

When user input is equal to 0(rock) and computer input is 1(scissor) then user wins.

When user input is equal to 1(scissor) and computer input is 2(paper) then user wins.

When user input is equal to 2(paper) and computer input is 0(rock) then user wins.

When user input is equal to 0(rock) and computer input is 1(paper) then computer wins.

When user input is equal to 1(scissor) and computer input is 0(rock) then computer wins.

When user input is equal to 2(paper) and computer input is 1(scissor) then computer wins.

When user input is equal to computer input then display "Its tie".

When user enter other input then display "enter valid number".

After while loop complete we calculate the points of user and computer and print the winner and there points.

HERE ARE THE CODE

import java.util.Scanner; import java.util.Random; public class stonepaper { public static void main(String[] args) { System.out.println("Lets play stone paper scissor with computer \n 0 for rock \n 1 for scissor \n 2 for paper "); // variables int computerpoint = 0; int userpoint = 0; int i=1; // gameloop while (i<=5) { // taking input from user System.out.println("Enter your play:"); Scanner sc = new Scanner(System.in); int userplay = sc.nextInt(); // taking input from computer and print the Random r=new Random(); int computerplay = r.nextInt(3); // printing the inputs of user and computer System.out.println("your play "+userplay); System.out.println("computer play "+computerplay); //conditions of game if(userplay==computerplay){System.out.println("Its tie");} else if(userplay==0 && computerplay==1 ){ System.out.println("you are winner"); userpoint += 1;} else if(userplay==1 && computerplay==2 ){ System.out.println("you are winner"); userpoint += 1;} else if(userplay==2 && computerplay==0 ){ System.out.println("you are winner"); userpoint += 1;} else if(userplay==0 && computerplay==2 ){ System.out.println("you are loser"); computerpoint += 1; } else if(userplay==1 && computerplay==0 ){ System.out.println("you are loser"); computerpoint += 1; } else if(userplay==2 && computerplay==1 ){ System.out.println("you are loser"); computerpoint += 1; } else{System.out.println("enter valid number");} i++; } // CALCULATING THE POINTS AND DISPLAYING POINTS OF USER AND COMPUTER if (computerpoint < userpoint) { System.out.println("you wins"); } else { System.out.println("computer wins"); } // printing the results System.out.println("your points: " + userpoint); System.out.println("computer points: " + computerpoint); }}
