代码实现

游戏的核心代码如下所示，首先获取玩家的输入，随机生成计算机的选择，然后根据规则判断胜负并输出结果。玩家也可以选择继续游戏或退出游戏。

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

public class RockPaperScissors {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        Random random = new Random();
        String[] hands = {"rock", "paper", "scissors"};

        System.out.println("Welcome to the game of Rock-Paper-Scissors!");

        while (true) {
            System.out.print("Please enter your choice: rock (r), paper (p), or scissors (s): ");
            String player_choice = sc.next().toLowerCase();

            int computer_choice = random.nextInt(3);
            String computer_hand = hands[computer_choice];

            System.out.printf("Your choice: %s\n", player_choice);
            System.out.printf("Computer choice: %s\n", computer_hand);

            if (player_choice.equals("r") && computer_hand.equals("scissors") ||
                    player_choice.equals("p") && computer_hand.equals("rock") ||
                    player_choice.equals("s") && computer_hand.equals("paper")) {
                System.out.println("You win!");
            } else if (player_choice.equals("r") && computer_hand.equals("paper") ||
                    player_choice.equals("p") && computer_hand.equals("scissors") ||
                    player_choice.equals("s") && computer_hand.equals("rock")) {
                System.out.println("You lose!");
            } else {
                System.out.println("Tie!");
            }

            System.out.print("Do you want to play again? (y/n): ");
            String again = sc.next().toLowerCase();

            if (!again.equals("y")) {
                System.out.println("\nThank you for playing!");
                break;
            }

            System.out.println();
        }
    }
}
