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）

break;
case 2:

break;
case 3:
str = "布";
break;
default:
System.out.println("未知错误");
break;
}
return str;
}
}
import java.util.Scanner;
public class Game {

private Computer computer;
private int count;
private int c_score;
private int u_score;
//初始化方法

System.out.println("-----------------欢迎进入游戏世界------------------");
System.out.println("\t **************************");

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）：");

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")){

}
//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){

}
}
//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("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。
