做一个java剪刀石头
java剪刀石头游戏，可以使用scanner类接收控制端输入的数值，利用if-else语句进行判断，实例如下：
import java.util.Scanner;
class Person {
int n = 0;
public int input() {
System.out.println("请输入：石头，剪刀，布");
Scanner sc = new Scanner(System.in);
String s = sc.next();
if(s.equals("石头")){
n = 1;
}else if(s.equals("剪刀")){
n = 2;
}else if(s.equals("布")){
n = 3;
}else if(s.equals("exit")){
System.out.print("系统退出了");
System.exit(0);
}
return n;
}
}
class Computer {
public int random() {
int h = (int)(Math.random()*3+1);
return h;
}
}
public class Game {
public void result(int n,int m){
if(n == m){
System.out.println("平了");
}else{
if(m==1){
if(n==2){
System.out.println("你输了");
}else if(n ==3){
System.out.println("你赢了");
}
}else if(m == 2) {
if(n == 1){
System.out.println("你赢了");
}else if(n ==3){
System.out.println("你输了");
}
}else if( m ==3 ){
if(n==1){
System.out.println("你输了");
}else if(n == 2){
System.out.println("你赢了");
}
}
}
}
public static void main(String[] args) {
while(true){
Person p = new Person();
Computer c = new Computer();
Game g = new Game();
g.result(p.input(), c.random());
}
}
}
用java编一个程序，实现两个人玩“石头、剪刀、布”，要求用枚举类型定义石头、剪刀、布
public class Test {
public enum Hand{//猜拳枚举
ROCK,SCISSORS,PAPER;
public static Hand getHand(int index){
Hand hand = null;
switch (index) {
case 0:
hand = Hand.ROCK;
break;
case 1:
hand = Hand.SCISSORS;
break;
case 2:
hand = Hand.PAPER;
break;
default:
hand = Hand.ROCK;
break;
}
return hand;
}
}
public static void main(String[] args) {
//两个人猜拳5次
for (int i = 0; i 5; i++) {
Hand hand1 = Hand.getHand((int)(Math.random()*3));
Hand hand2 = Hand.getHand((int)(Math.random()*3));
judge(hand1, hand2);
}
}
private static void judge(Hand hand1,Hand hand2){
if(hand1 == Hand.ROCK){
if(hand2 == Hand.ROCK){
System.out.println("第一个出拳头，第二个出拳头，平局");
}else if(hand2 == Hand.SCISSORS){
System.out.println("第一个出拳头，第二个出剪刀，第一个赢");
}else if(hand2 == Hand.PAPER){
System.out.println("第一个出拳头，第二个出布，第二个赢");
}
}else if(hand1 == Hand.SCISSORS){
if(hand2 == Hand.ROCK){
System.out.println("第一个出剪刀，第二个出拳头，第二个赢");
}else if(hand2 == Hand.SCISSORS){
System.out.println("第一个出剪刀，第二个出剪刀，平局");
}else if(hand2 == Hand.PAPER){
System.out.println("第一个出剪刀，第二个出布，第一个赢");
}
}else if(hand1 == Hand.PAPER){
if(hand2 == Hand.ROCK){
System.out.println("第一个出布，第二个出拳头，第一个赢");
}else if(hand2 == Hand.SCISSORS){
System.out.println("第一个出布，第二个出剪刀，第二个赢");
}else if(hand2 == Hand.PAPER){
System.out.println("第一个出布，第二个出布，平局");
}
}
}
}
应该不是最优解决办法，先这么着把
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;
}
}
急求一个JAVA编程，“编写一个猜拳游戏，分别用0、1、2表示石头、剪子、布。
用我自己的方法写了一个，看LZ喜欢不喜欢
12是石头，23是剪子，31是布.first表示第一个人。second表示第二个人!
import java.util.Random;
public class Print {
public static void main(String[] args) {
//"12"是石头，“23”是剪子，“31”是布
String[] a = {"12", "23", "31"};
Random r = new Random ();
String first = a[r.nextInt(3)];
String second = a[r.nextInt(3)];
System.out.println("12是石头，23是剪子，31是布.first表示第一个人。second表示第二个人!\n---------");
if (first.equals(second)) {
System.out.println(first + "--" + second + ",(前面是first,后一个是second)" + ":平了");
} else if (first.charAt(1) == second.charAt(0)) {
System.out.println("出拳情况:" + first + "--" + second + ",(前面是first,后一个是second)" + "\n结果判断：" + result1(first,second));
} else if (first.charAt(0) == second.charAt(1)) {
System.out.println("出拳情况:" + first + "--" + second + ",(前面是first,后一个是second)" + "\n结果判断：" + result2(first,second));
}
}
public static String result1 (String f, String s) {
if (f.equals("12") s.equals("23")) {
return "first石头 胜 second剪子";
} else if (f.equals("23") s.equals("31")) {
return "first剪子 胜 second布";
} else {
return "first布 胜 second石头";
}
}
public static String result2 (String f, String s) {
if (f.equals("12") s.equals("31")) {
return "first石头 输 second布";
} else if (f.equals("23") s.equals("12")) {
return "first剪子 输 second石头";
} else {
return "first布 输 second剪子";
}
}
}
