java人机猜拳
1.首先定义一个用户类：代码如下
package mypackage;
import java.util.*;
public class Person {
String name="";
int score;
public int showFist()
{
System.out.println("请出拳：1.剪刀2.石头3.布(输入相应数字)");
Scanner input =new Scanner(System.in);
int number=input.nextInt();
switch(number)
{
case 1:
System.out.println("玩家出:剪刀");
return number;
case 2:
System.out.println("玩家出:石头");
return number;
case 3:
System.out.println("玩家出:布");
return number;
default:
System.out.println("你出拳：剪刀");
return number;
}
}
}
2.定义一个计算机类
package mypackage;
public class Computer {
int max =3;
int min =1;
int number= (int)(Math.random()*(max-min))+min;
int score;
String name="电脑";
public int showcomputer()
{
switch(number)
{
case 1:
System.out.println("电脑出：剪刀");
return number;
case 2:
System.out.println("电脑出;石头");
return number;
case 3:
System.out.println("电脑出：布");
return number;
default:
System.out.println("电脑出：剪刀");
return number;
}
}
}
3.创建一个游戏类
package mypackage;
import java.util.*;
public class StartGame
{
public int Initial()
{
System.out.println("----------欢迎进入游戏世界----------");
System.out.println("");
System.out.println("\t****************");
System.out.println("\t** 猜拳，开始**\t\t");
System.out.println("\t****************");
System.out.println("");
System.out.println("出拳规则：1.剪刀2.石头3.布");
System.out.println("请选择对方角色(1.刘备2.孙权3.曹操)：");
Scanner input =new Scanner(System.in);
int number=input.nextInt();
switch(number)
{
case 1:
System.out.print("刘备");
return number;
case 2:
System.out.print("孙权");
return number;
case 3:
System.out.print("曹操");
return number;
default:
System.out.print("你选择了刘备作战");
return number;
}
}
public static void main(String[] args)
{
//完善游戏类的startGame()方法，实现一局对战
Computer computer =new Computer();
Person player =new Person();
StartGame come =new StartGame();
Scanner input =new Scanner(System.in);
come.Initial();
System.out.println("");
System.out.println("要开始么？y/n\n\n");
String con =input.next();
int count=0;
while(con.equalsIgnoreCase("y"))
{
int perFist=player.showFist();
int compFist=computer.showcomputer();
System.out.println("双方对战次数:" + count);
if((perFist==1&&compFist==1)||(perFist==2&&compFist==2)||(perFist==3&&com pFist==3))
{
System.out.println("结果：平局，真衰!");
count++;
}else
if((perFist==1&&compFist==3)||(perFist==2&&compFist==1)||(perFist==3&&compFist ==2))
{
System.out.println("结果：恭喜，你赢了！");
player.score++;
}
else{
System.out.println("结果说，你输了，真笨!\n");
count++;
computer.score++;
}
System.out.println(+ "积分为：" + player.score+ "\t\t" + + "积分为：" + computer.score);
System.out.println("是否继续？y/n");
con =input.next();
}
while(con.equals("n"))
{
if(player.score > computer.score) {
System.out.println("最终结果：" + + "在" + count + "回合中战胜了" + );
break;
}
else if(player.score < computer.score) {
System.out.println("最终结果：" + + "在" + count + "回合中战胜了" + );
break;
}
else {
System.out.println("最终结果：" + + "在" + count + "回合中和" + + "战平");
break;}
}
}
}
