Q5: 猜拳游戏java能输出游戏时间
Java实现猜拳游戏的核心在于电脑随机数的生成，Java中的随机数生成方法是：
首先引入包 import java.util.*; 然后 int r=new Random().nextInt(3); （nextInt中的数字三代表随机数生成的个数，从零开始）
所以在猜拳的输入中需要有0、1、2三个数字代替，如果要输入汉字，则用if进行相应判断即可。
在实现的游戏中实现①猜拳；②记录胜负；③玩家决定游戏局数；④输出获胜、失败及平局；⑤统计总共的胜负结果（根据获胜次数判断）
①猜拳基础功能：该部分代码可以放到一个方法中，减少主函数代码量。
电脑出拳即 int r=new Random().nextInt(3); 注意：该部分一定要写在for循环内部，否则无法实现每次不同的随机数。
通过if判断双方出拳是否相等 if(a==0r==0) else if(a==0r==1) else if(a==0r==2) 即可实现猜拳，if内直接输出相关语句即可
②记录胜负： 定义猜拳方法为int ，通过返回值记录相关比赛的胜负情况 ,可以用0--失败；1--获胜；2--平局 进行记录，在主函数中对相应抛出的数字记录即可
if(a==0r==0){
System.out.println("The computer comes out with cloth,it was a draw. ");
return 2;
}
h=comp.compare(a,r); if (h==1) j++;

③玩家决定局数： 定义一个数，在循环中不大于该数即可
④输出获胜、失败及平局： j、k即胜利和失败，平局数即n-j-k。
⑤统计结果，直接用if比较i、j的数字结果即可。
主函数部分：
package SS2_5;
import java.util.*;
public class Main {
public static void main(String args[]){
Scanner scanner=new Scanner(System.in);
Compare comp=new Compare();
int h=0,j=0,k=0;
System.out.println("rules:0--cloth;1--stone;2--scissors.\nU can choose how many times you want to play:");
int n=scanner.nextInt();
for(int i=1;i=n;i++){
System.out.print("It's the "+i+" round,your turn:");
int a=scanner.nextInt();
int r=new Random().nextInt(3);
switch (a){
case 0:
h=comp.compare(a,r);
break;
case 1:
h=comp.compare(a,r);
break;
case 2:
h=comp.compare(a,r);
break;
default:
System.out.println("Wrong number!");
break;
}
if (h==1)
j++;
else if(h==0)
k++;
}
System.out.println("The total times you won are "+j+",The draw times are "+(n-j-k)+".");
if(jk)
System.out.println("You are the final winner");
else if(kj)
System.out.println("The computer is the winner.");
if(j==k)
System.out.println("The final result is draw");
}
}

compare方法部分
package SS2_5;
public class Compare {
public int compare(int a,int r){
int counter=0;
if(a==0r==0){
System.out.println("The computer comes out with cloth,it was a draw. ");
return 2;
}
else if(a==0r==1){
System.out.println("The computer comes out with stone, you won. ");
return 1;
}
else if(a==0r==2){
System.out.println("The computer comes out with scissor,you lost. ");
return 0;
}
else if(a==1r==0){
System.out.println("The computer comes out with cloth,you lost. ");
return 0;
}
else if(a==1r==1){
System.out.println("The computer comes out with stone,it was a draw. ");
return 2;
}
else if(a==1r==2){
System.out.println("The computer comes out with scissors,you won. ");
return 1;
}
else if(a==2r==0){
System.out.println("The computer comes out with cloth,you won. ");
return 1;
}
else if(a==2r==1){
System.out.println("The computer comes out with stone,you lost. ");
return 0;
}
else if(a==2r==2){
System.out.println("The computer comes out with scissors,it was a draw. ");
return 2;
}
else
return 0;
}
