java实现简单猜拳小游戏

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

user.java

import java.util.scanner;
public class user {
    string name;
    int score;
    public int showfist(){
        system.out.println ("请出拳：1.剪刀\t2.石头\t3.布");
        scanner input=new scanner ( system.in );
        int choice=input.nextint ();
        if(choice==1){
            system.out.println ("您出了剪刀");
        }else if(choice==2){
            system.out.println ("您出了石头");
        }else if (choice==3){
            system.out.println ("您出了布");
        }else {
            system.out.println ("输入有误！");
        }
        return choice;
    }
}

computer.java

public class computer {
    string name;
    int score;

    public int showfist () {
        int choice = (int) (math.random () * 3) + 1;    //产生随机数
        if (choice == 1) {
            system.out.println (name +"出了剪刀" );
        } else if (choice == 2) {
            system.out.println (name +"出了石头" );
        } else if (choice == 3) {
            system.out.println (name +"您出了布" );
        } else {
            system.out.println ( "输入有误！" );
        }
        return choice;
    }
}
