how to make rock paper scissors in java code example

Example 1: rock paper scissors java

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

public class RockPaperScissors {

        System.out.println("Play again? Y(8), N(9)?");

            return true;
        default:
            System.out.println("Thanks for playing!");
            return false;
        }
    }

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        RPSPlayer computer = new RandomComputerPlayer(new Random());
        RPSPlayer human = new HumanPlayer(scanner);

        System.out.println("Rock Paper Scissors, by 200_success!");
        do {
            String comp = computer.play();
            String you = human.play();

            System.out.printf("%s vs. %s", comp, you);
            if (you.equals(comp)) {
                System.out.println(", IT'S A TIE!");
            } else if ( ("Rock".equals(you) && "Scissors".equals(comp)) ||
                        ("Scissors".equals(you) && "Paper".equals(comp)) ||
                        ("Paper".equals(you) && "Rock".equals(comp)) ) {
                System.out.println("! You win!");
            } else {
                assert (("Rock".equals(comp) && "Scissors".equals(you)) ||
                        ("Scissors".equals(comp) && "Paper".equals(you)) ||

    }
}

Example 2: rock paper scissors java

import java.util.Scanner;

        int yes= 8, no = 9;
        int input;
        input = sage.nextInt();

            if(input == yes){
