任务
1.完成人机猜拳互动游戏的开发
主要功能
1.选取对战角色
2.猜拳
3.记录分数
方法思路:
创建用户类User来实现用户出拳创建电脑类Computer来实现电脑出拳创建游戏类Game来实现猜拳游戏,其中方法Judge实现判断本局输赢StartGame方法实现菜单打印以及循环游戏并判断最终结果。
具体实现如下
1.实现User类:
import java.util.Scanner;
public class User {
public int showFist(int i) {//打印用户出拳
switch (i) {
case 1:
System.out.println("你出拳:剪刀");
break;
case 2:
System.out.println("你出拳:石头 ");
break;
case 3:
System.out.println("你出拳:布");
break;
default:
System.out.println("输入错误,请重新输入:");
break;
}
return i;
}
}
2.实现Computer类:
import java.util.Random;
public class Computer {
int showHand = 0;//记录所出拳
String heroName;//储存对战英雄名称
public void showFist() {//电脑随机出拳并打印电脑出拳
Random sc = new Random();
showHand = sc.nextInt(3) + 1;
switch (showHand) {
case 1:
System.out.println(heroName + "出拳:" + "剪刀");
break;
case 2:
System.out.println(heroName + "出拳:" + "石头");
break;
case 3:
System.out.println(heroName + "出拳:" + "布");
break;
}
}
public String getHeroName(int i) {
switch (i) {
case 1:
heroName = "刘备";
break;
case 2:
heroName = "孙权";
break;
case 3:
heroName = "曹操";
break;
}
return heroName;
}
}
3.实现Game类:
import java.util.Scanner;
public class Game {
int score = 0;//平局统计
int score1 = 0;//电脑胜利数
int score2 = 0;//玩家胜利数
Computer computer =new Computer();
User user=new User();
public int judge(int i)//判断此局胜负,并记录分数
{
Game game=new Game();
if (i == computer.showHand) {
System.out.println("和局,嘿嘿,等着瞧吧!");
System.out.println();
score++;
} else if (i == 1 && computer.showHand == 2) {
System.out.println("你输了,真笨!");
System.out.println();
score1++;
} else if (i == 1 && computer.showHand == 3) {
System.out.println("恭喜,你赢了!");
System.out.println();
score2++;
} else if (i == 2 && computer.showHand == 1) {
System.out.println("此局:恭喜,你赢了");
score2++;
} else if (i == 2 && computer.showHand == 3) {
System.out.println("此局:很遗憾,你输了");
score1++;
} else if (i == 3 && computer.showHand== 1) {
System.out.println("此局:很遗憾,你输了");
score1++;
} else if (i == 3 && computer.showHand == 2) {
System.out.println("此局:恭喜,你赢了");
score2++;
}
return i;
}
public void startGame() {
Game game=new Game();
System.out.println("********************");//打印菜单
System.out.println("******猜拳,开始******");
System.out.println("********************");
System.out.println("出拳规则:1,剪刀 2,石头 3,布");
System.out.println("请选择你想和谁对战(1:刘备 2:孙权 3:曹操):");
Scanner sc = new Scanner(System.in);
int a = sc.nextInt();
computer.getHeroName(a);//获取用户所寻找对象
System.out.println("请输入你的名字:");
String name = sc.next();//录入用户信息
switch (a) {
case 1:
System.out.println("你选择了刘备对战");
break;
case 2:
System.out.println("你选择了刘邦对战");
break;
case 3:
System.out.println("你选择了曹操对战");
break;
}
System.out.println(name + "vs" + computer.heroName + "对战");
int court = 1;//储存对战局数
System.out.print("要开始吗?(y/n):");
Scanner sr = new Scanner(System.in);
String choose = sr.next();
while (true) {//死循环来重复进行游戏直到用户退出游戏
if (choose.equals("n")) {
System.out.println("结束");
return;
} else if (choose.equals("y")) {
System.out.print("请出拳:1.剪刀 2.石头 3.布(输入相应数字):");
int c = sr.nextInt();//获取用户出拳
user.showFist(c);//打印用户出拳
computer.showFist();//打印电脑出拳
judge(c);//判断本局结果并打印
System.out.println("是否开始下一轮(y/n):");
System.out.println("------------------------------------------");
String m = sr.next();//获取用户是否想要进行下一轮比赛
if (m.equals("y")) {
court++;//累加一次比赛局数
} else if (m.equals("n")) {
System.out.println("------------------------------------------");//打印比赛最后比分
System.out.println(computer.heroName + "VS" + name);
System.out.println("对战次数:" +court + " " + "平局" + score + "次");
System.out.println("姓名" + " " + "得分");
System.out.println(name + " " + score2);
System.out.println(computer.heroName + " " +score1);
if (score1 < score2)//打印比赛最后结果
{
System.out.println("恭喜恭喜,你赢得了比赛!");
break;
} else if (score1 ==score2) {
System.out.println("打成平手,下次和你一较高下!");
break;
} else {
System.out.println("呵呵,笨笨,下次加油啊!");
break;
}
}
}
}
}
}
具体运行如下
至此,人机猜拳已经完成,有什么问题欢迎来询问!
