java_猜拳小游戏——流之奥义

话不多说，直接上代码。

一、先来几个工具类下下饭。

1、输入操作限制型的工具类（TSUtility）

package MathDemo;

import java.util.Random;
import java.util.Scanner;
import java.util.regex.Pattern;

public class TSUtility {
    private static Scanner scanner = new Scanner(System.in);

    public static char readMenuSelection() {
        char c;
        for (; ; ) {
            String str = readKeyBoard(1, false);
            c = str.charAt(0);
            if (c != '1' && c != '2' &&
                    c != '3' && c != '4') {
                System.out.print("选择错误，请重新输入：");
            } else break;
        }
        return c;
    }

    public static char readMenuSelectionPro() {
        char c;
        for (; ; ) {
            String str = readKeyBoard(1, false);
            c = str.charAt(0);
            if (c != '1' && c != '2' &&
                    c != '3' && c != '4' && c != '5') {
                System.out.print("选择错误，请重新输入：");
            } else break;
        }
        return c;
    }


    public static void readReturn() {
        System.out.print("按回车键继续...");
        readKeyBoard(100, true);
    }

    public static int readInt() {
        int n;
        for (; ; ) {
            String str = readKeyBoard(2, false);
            try {
                n = Integer.parseInt(str);
                break;
            } catch (NumberFormatException e) {
                System.out.print("数字输入错误，请重新输入：");
            }
        }
        return n;
    }

    public static int readstock() {
        int n;
        for (; ; ) {
            String str = readKeyBoard(6, false);
            try {
                n = Integer.parseInt(str);
                break;
            } catch (NumberFormatException e) {
                System.out.print("数字输入错误，请重新输入：");
            }
        }
        return n;
    }

    public static Double readDouble() {
        Double n;
        for (; ; ) {
            String str = readKeyBoard(6, false);
            try {
                n = Double.parseDouble(str);
                break;
            } catch (NumberFormatException e) {
                System.out.print("数字输入错误，请重新输入：");
            }
        }
        return n;
    }

    public static char readConfirmSelection() {
        char c;
        for (; ; ) {
            String str = readKeyBoard(1, false).toUpperCase();
            c = str.charAt(0);
            if (c == 'Y' || c == 'N') {
                break;
            } else {
                System.out.print("选择错误，请重新输入：");
            }
        }
        return c;
    }

    public static String readString(int limit, String defaultValue) {
        String str = readKeyBoard(limit, true);
        return str.equals("") ? defaultValue : str;
    }

    public static String readKeyBoard(int limit, boolean blankReturn) {
        String line = "";

        while (scanner.hasNextLine()) {
            line = scanner.nextLine();
            if (line.length() == 0) {
                if (blankReturn) return line;
                else continue;
            }

            if (line.length() < 1 || line.length() > limit) {
                System.out.print("输入长度（不大于" + limit + "）错误，请重新输入：");
                continue;
            }
            break;
        }

        return line;
    }

    public static void loadSpecialEffects() throws InterruptedException {
        System.out.println("请稍等：");
        for (int i1 = 1; i1 <= 100; i1++) {
            System.out.print("加载中：" + i1 + "%");
            Thread.sleep(new Random().nextInt(25) + 1);
            if (i1 == 100) {
                Thread.sleep(50);
            }
            System.out.print("\r");
        }
    }

    //把全为数字的字符串转换为int类型，并返回其数值
    public static int printInt(String x){
        Scanner sc = new Scanner(System.in);
        if(isNumberic(x)==true){
            int y = Integer.parseInt(x);
            return y;
        }else{
            while(true){
                System.out.print("你输入的值无意义! 请你重新输入: ");
                String num = sc.next();
                if(isNumberic(num)==true){
                    int y1 = Integer.parseInt(num);
                    return y1;
                }

            }
        }
    }

    //判断字符串是否全是数字，是返回true，否则返回false
    public static boolean isNumberic(String str) {
        //使用正则表达式进行判断是否全为数字
        Pattern pattern = Pattern.compile("[0-9]*");
        return pattern.matcher(str).matches();
    }
}

2、图片显示工具类（PayView）

import javax.imageio.ImageIO;
import javax.swing.*;
import java.awt.*;
import java.io.File;

/*
 *生成二维码
 *下面代码只需要换一个图片即可
 *new PayView();//创建这个对象即可展示支付图片
 */

public class PayView extends JFrame{
    MyPanel mp=null;
    public PayView(){
        mp=new MyPanel();
        this.add(mp);
        this.setSize(1273, 809);
        this.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
        this.setVisible(true);
    }

    public static void main(String[] args){
        new PayView();
    }
}

class MyPanel extends JPanel{

    Image image=null;

    public void paint(Graphics g){
        try {
            image= ImageIO.read(new File("eighth\\src\\MathDemo\\name\\看了就要负责.jpg"));
            g.drawImage(image, 0, 0, 1273, 809, null);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

 二、登录界面的功能

/*
登录界面
 */

import java.io.File;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import java.util.Properties;
import java.util.Random;
import java.util.Scanner;

public class loginView {
    public static final Scanner sc=new Scanner(System.in);
    public static int money=0;
    public static int count=1;

    //用户登录注册

                System.out.println("你输入的账户信息不存在，请选择是否注册（y/n）。");
                char c=TSUtility.readConfirmSelection();

                    TSUtility.loadSpecialEffects();
                    System.out.println("注册成功。");
                }else {
                    System.out.println("已取消注册,请问是否要退出系统（y/n）");

        }
    }
}

三、单独写的猜拳游戏类

import java.io.FileWriter;
import java.io.IOException;
import java.util.Properties;
import java.util.Random;
import java.util.Scanner;

public class HandGame {

    public static void handGame() throws IOException {
        System.out.println("规则如下：");
        System.out.println("1代表剪刀、2代表石头、3代表布。剪刀<石头<布，石头<布<剪刀，布<剪刀<石头");
        System.out.println("-------------------");
        FileWriter fw=new FileWriter("eighth\\src\\MathDemo\\name\\系统拳.txt");
        fw.write("1=剪刀\r\n");
        fw.write("2=石头\r\n");
        fw.write("3=布\r\n");
        fw.close();

        Properties prop=new Properties();
        prop.setProperty("1","剪刀");
        prop.setProperty("2","石头");
        prop.setProperty("3","布");

        while (true){
            Scanner sc=new Scanner(System.in);
            System.out.println("石头2、剪刀1、布3！！！给我比个手出来。laozi要数字。");
            int hand=sc.nextInt();

            Random r=new Random();
            int i = r.nextInt(3)+1;

            if (hand==1 && i==1){
                System.out.println("你出的是："+prop.getProperty(String.valueOf(hand)));
                System.out.println("系统出的是："+prop.getProperty(String.valueOf(i)));
                System.out.println("你居然跟系统拳打成平手？laji...");
            }else if (hand==1 && i==2){
                System.out.println("你出的是："+prop.getProperty(String.valueOf(hand)));
                System.out.println("系统出的是："+prop.getProperty(String.valueOf(i)));
                System.out.println("然后呢？你输了？ztmlaji...");
            }else if (hand==1 && i==3){
                System.out.println("你出的是："+prop.getProperty(String.valueOf(hand)));
                System.out.println("系统出的是："+prop.getProperty(String.valueOf(i)));
                System.out.println("这就赢了？啊tui，dtmlaji...");
            }else if (hand==2 && i==1){
                System.out.println("你出的是："+prop.getProperty(String.valueOf(hand)));
                System.out.println("系统出的是："+prop.getProperty(String.valueOf(i)));
                System.out.println("这就赢了？啊tui，dtmlaji...");
            }else if (hand==2 && i==2){
                System.out.println("你出的是："+prop.getProperty(String.valueOf(hand)));
                System.out.println("系统出的是："+prop.getProperty(String.valueOf(i)));
                System.out.println("你居然跟系统拳打成平手？laji...");
            }else if (hand==2 && i==3){
                System.out.println("你出的是："+prop.getProperty(String.valueOf(hand)));
                System.out.println("系统出的是："+prop.getProperty(String.valueOf(i)));
                System.out.println("然后呢？你输了？ztmlaji...");
            }else if (hand==3 && i==1){
                System.out.println("你出的是："+prop.getProperty(String.valueOf(hand)));
                System.out.println("系统出的是："+prop.getProperty(String.valueOf(i)));
                System.out.println("然后呢？你输了？ztmlaji...");
            }else if (hand==3 && i==2){
                System.out.println("你出的是："+prop.getProperty(String.valueOf(hand)));
                System.out.println("系统出的是："+prop.getProperty(String.valueOf(i)));
                System.out.println("这就赢了？啊tui，dtmlaji...");

            }

            System.out.println("-------------------");
            System.out.println("还想继续玩？傻子吧还玩？ y/n");
            char c = TSUtility.readConfirmSelection();
            if (c != 'Y') {

                System.out.println("已退出游戏！(早该走了...)");
                break;
            }
        }
    }
}

四、以上就是全部代码，这个游戏就这样。
