使用java实现猜拳小游戏

本文实例为大家分享了java实现猜拳小游戏的具体代码，供大家参考，具体内容如下

实现下图要求

public class User {
 
 private String u_name;
 
 private int u_score;
 
 public User() {
  super();
 }
 
 public User(String name, int score) {
  super();
  this.u_name = name;
  this.u_score = score;
 }
 
 public String getName() {
  return u_name;
 }
 
 public void setName(String name) {
  this.u_name = name;
 }
 
 public int getScore() {
  return u_score;
 }
 
 public void setScore(int score) {
  this.u_score = score;
 }
 /**
  * 出拳方法
  * @param choice 选择的数字代表出拳（1：石头2：剪刀3：布）
  * @return str 返回你所选择的出拳
  */
 public String chuQuan(int choice){
  String str = "";
  switch (choice) {
  case 1:
   str = "石头";
   break;
  case 2:
   str = "剪刀";
   break;
  case 3:
   str = "布";
   break;
  default:
   System.out.println("未知错误");
   break;
  }
  return str;
 }
 
}

public class Computer {
 
 private String c_name;
 
 private int c_score;
 
 public String getName() {
  return c_name;
 }
 
 public void setName(String name) {
  this.c_name = name;
 }
 
 public int getScore() {
  return c_score;
 }
 
 public void setScore(int score) {
  this.c_score = score;
 }
     /**
  * 出拳方法
  * @param choice 选择的数字代表出拳（1：石头2：剪刀3：布）
  * @return str 返回你所选择的出拳
  */
 public String chuQuan(int choice){
  String str = "";
  switch (choice) {
  case 1:
   str = "石头";
   break;
  case 2:
   str = "剪刀";
   break;
  case 3:
   str = "布";
   break;
  default:
   System.out.println("未知错误");
   break;
  }
  return str;
 }
}

import java.util.Scanner;
 
public class Game {
 
 Scanner input = new Scanner(System.in);

  System.out.println("-----------------欢迎进入游戏世界------------------");
  System.out.println("\t   **************************");
  System.out.println("\t\t**  猜拳，开始    **");
  System.out.println("\t   **************************");
  System.out.println();
  System.out.println("出拳规则：1.石头  2.剪刀  3.布");
  System.out.print("请选择对方角色：（1：曹操  2：孙权  3：刘备）：");
  int key = input.nextInt();
  switch (key) {
  case 1:
   computer.setName("曹操");
   break;
  case 2:
   computer.setName("孙权");
   break;
  case 3:
   computer.setName("刘备");
   break;
  default:
   System.out.println("非法输入...");
   break;
  }
  System.out.print("请输入你的姓名：");
  user.setName(input.next());
  System.out.println(user.getName()+"  VS  "+computer.getName());
  begin();
 }
 
 //是否开始执行  循环执行直到输入n结束
 public void begin(){
  System.out.print("要开始吗（y/n）：");
//  boolean falg = true;
  String str = input.next();
  if(str.equals("y")){
   while(true){
    score();
    System.out.print("是否开始下一轮：（y/n）");
    String str1 = input.next();
    count++;
    if(str1.equals("y")){
     
    }else{
//     falg = false;
     break;
    }
   }
  }
  show();
 }
 
 //人和机器出拳并判断胜负 此处计算比赛次数 双方得分
 public void score(){
  System.out.print("请出拳：");
  int choice1 = input.nextInt();
  String str1 = user.chuQuan(choice1);
  int choice2 = (int)(Math.random()*3+1);
  String str2 = computer.chuQuan(choice2);
  System.out.println("你出拳"+str1);
  System.out.println(computer.getName()+"出拳"+str2);
  if(choice1 == choice2){
   System.out.println("结果：平局");
   
  }else if(choice2-choice1==-1||choice2-choice1==2){
   System.out.println("结果："+computer.getName()+"获胜...");
   c_score++;
   computer.setScore(c_score);
  
  }else if(choice1-choice2==-1||choice1-choice2==2){
   System.out.println("结果：恭喜你，你获胜...");
   u_score++;
   user.setScore(u_score);
 
  }
 }
 
 //显示比赛结果并比较得得出最后胜负
 public void show(){
  System.out.println("--------------------------------");
  System.out.println(user.getName()+"  VS  "+computer.getName());
  System.out.println("对战次数："+count+"\n\n");
  System.out.println("姓名\t得分");
  System.out.println(user.getName()+"\t"+user.getScore());
  System.out.println(computer.getName()+"\t"+computer.getScore()+"\n");
  if(user.getScore()>computer.getScore()){
   System.out.println("结果：恭喜恭喜");
  }else if(user.getScore()<computer.getScore()){
   System.out.println("结果：再接再厉");
  }else{
   System.out.println("结果：平局");
  }
  System.out.println("--------------------------------");
 }
 
}

测试类

public class Test {
 
 public static void main(String[] args) {
  // TODO Auto-generated method stub
  Game game = new Game();
  game.init();
 }
 
}

这样猜拳小游戏就实现了。
