用Java语言编写剪刀石头布，效果如下
import java.util.Random;
import java.util.Scanner;
public class FingerGuessingGame {
private static Scanner sc;
private static Random rad;
private static final String[] FINGERS = {"剪刀", "石头", "布"};
private static int win = 0, loose = 0, draw = 0;
public static void main(String[] args) {
sc = new Scanner(System.in);
rad = new Random();
while(true) {
System.out.println("~~~~~~~~~~~~剪刀石头布游戏，输入E可以退出~~~~~~~~~~~");
System.out.println("请选择你要出什么？Z——剪刀，X——石头，C——布");
String command = sc.nextLine();
int playerFinger = getValue(command);
if(playerFinger == -1) {
break;
} else if(playerFinger == 3) {
System.out.println("输入错误，请参考说明！");
continue;
}
System.out.println("你出的是" + FINGERS[playerFinger]);
int cpuFinger = rad.nextInt(3);
System.out.println("计算机出的是" + FINGERS[cpuFinger]);
int result = playerFinger - cpuFinger;
if(0 == result) {
System.out.println("平局！");
draw ++;
} else if(-1 == result) {
System.out.println("你输了！");
loose ++;
} else {
System.out.println("你赢了！");
win ++;
}
}
System.out.println("游戏结束！\r\n游戏统计次数");
System.out.println(String.format("赢：%d\r\n输：%d\r\n平局：%d", win, loose, draw));
}
private static int getValue(String command) {
if(command.equalsIgnoreCase("E")) {
return -1;
}
if(command.equalsIgnoreCase("Z")) {
return 0;
}
if(command.equalsIgnoreCase("X")) {
return 1;
}
if(command.equalsIgnoreCase("C")) {
return 2;
}
return 3;
}
}
如何用JAVA设计一个游戏，电脑和人玩剪刀石头布游戏，并且能显示游戏结果？
写了一下，结果输出到桌面上，你把文件输出路径改成你的桌面路径就可以了，不知道你要不要最终结果
代码：
package com.hmall;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import java.util.Random;
import java.util.Scanner;
/**
* @ClassName Mora
* @Description TODO
* @Author dell
* @Date 2019/7/1 13:03
* @Version 1.0
**/
public class Mora {
private static String calculate(String input) {
ListString list = new ArrayList();
list.add("拳头");
list.add("剪刀");
list.add("布");
Random r = new Random();
Integer random = r.nextInt(3);
String temp = list.get(random);
if (temp.equals(input)) {
return "您出了" + input + ",电脑出了" + temp + ",结果为平局";
} else {
if (input.equals("拳头")) {
if (temp.equals("剪刀")) {
return "您出了" + input + ",电脑出了" + temp + ",结果为您赢了";
} else {
return "您出了" + input + ",电脑出了" + temp + ",结果为您输了";
}
} else if (input.equals("剪刀")) {
if (temp.equals("拳头")) {
return "您出了" + input + ",电脑出了" + temp + ",结果为您输了";
} else {
return "您出了" + input + ",电脑出了" + temp + ",结果为您赢了";
}
} else if (input.equals("布")) {
if (temp.equals("拳头")) {
return "您出了" + input + ",电脑出了" + temp + ",结果为您赢了";
} else {
return "您出了" + input + ",电脑出了" + temp + ",结果为您输了";
}
} else {
return "输入数据有误";
}
}
}
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
Integer count;
while (true) {
System.out.println("请输入比赛场次(不能小于5):");
count = scanner.nextInt();
if (count = 5) {
System.out.println("比赛开始");
break;
}
System.out.println("输入小于5，请重新输入");
}
String input;
File f = new File("C:\\Users\\dell\\Desktop\\result.txt");
try {
BufferedWriter bw = new BufferedWriter(new FileWriter(f));
for (int i = 0; i count; i++) {
System.out.println("请输入您的选择:");
input = scanner.next();
String result = calculate(input);
bw.write(result);
bw.newLine();
System.out.println(result);
}
bw.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
结果：
java 剪刀石头布 这个游戏怎么用数组来实现，我把脑壳都想破了
import java.util.*;
public class Exam
{
public static void main(String[] args)
{
String[] cq={"石头","剪刀","布"};
String guess;
int youwin=0,mewin=0,daping=0,total=0,n;
Random r=new Random();
Scanner sc=new Scanner(System.in);
while(true)
{
n=r.nextInt(3);
System.out.print("石头、剪刀、布，我已出，请你出（输入exit退出循环）：");
guess=sc.nextLine();
if(guess.equals("exit"))
{
break;
}
else
{
total++;
System.out.print("这一次你出的是"+guess+"，我出的是"+cq[n]+"，所以");
if(guess.equals("石头")1==n || guess.equals("剪刀")2==n || guess.equals("布")0==n)
{
youwin++;
System.out.println("你赢了！");
}
else if(guess.equals(cq[n]))
{
daping++;
System.out.println("我们打平了！");
}
else
{
mewin++;
System.out.println("我赢了！");
}
}
}
System.out.println("总共玩了"+total+"次，你赢了"+youwin+"次，我赢了"+mewin+"次，打平"+daping+"次！");
}
}
