how to make a rock, paper, scissors game java code example

Example 1: rock paper scissors java

import java.util.Scanner;

public class HumanPlayer implements RPSPlayer {
    private final Scanner scanner;

    public HumanPlayer(Scanner scanner) {
        this.scanner = scanner;
    }

    public String play() {
        System.out.println("Select 1, 2, or 3 for Rock, Paper, Scissors");
        int choice = this.scanner.nextInt();
        // Keeping things simple, not doing any validation here
        return CHOICES[choice - 1];
    }
}

Example 2: rock paper scissors java

import java.util.Scanner;
import java.util.Random;

public class rps {
    public static void main (String args[]){
        int input;
        int b = 1;
        Scanner sage = new Scanner(System.in);
        Random rnd = new Random();
    System.out.println("Rock Paper Scissors, by Sage!");
    System.out.println("Select 1, 2, 3, for Rock, Paper, Scissors");
    //Menu Present, pretty bad still

        while (b != 0){
        int rock = 1, paper = 2, scissors = 3;
        input = sage.nextInt();
        int randomNumber = rnd.nextInt(3-1+1)+1;

            if(randomNumber == rock){
                if(input == rock){
                    System.out.println("Rock vs. Rock, ITS A TIE!");
            }    else if(input == paper){
                    System.out.println("Rock vs. Paper! You win!" );
            }    else if(input == scissors){
                    System.out.println("Rock vs. Scissors! You lose!");
            }  //These blocks establish options if the computer got Rock

            else if(randomNumber == paper){
                if(input == rock){
                    System.out.println("Paper vs. Rock! You lose!");
            }   else if(input == scissors){
                    System.out.println("Paper vs. Scissors! You win!");
            }   else if(input == paper){
                    System.out.println("Paper vs. Paper! Its a tie!");
            } //These blocks establish the options if comp. got paper

            else if(randomNumber == scissors){
                if(input == rock){
                    System.out.println("Scissors vs. Rock! You win!");
            }   else if(input == scissors){
                    System.out.println("Scissors vs. Scissors, ITS A TIE!");
            }   else if(input == paper){
                    System.out.println("Scissors vs Paper! You lose!");
            } //These blocks establish if the computer got scissors.

            }
            }
            rps2 rps2Object = new rps2();
            rps2Object.rps2();


        }
