JAVASE系统实现抽卡功能

本文实例为大家分享了JAVASE系统实现抽卡功能的具体代码，供大家参考，具体内容如下

先看下文件结构

使用到的知识点：

看下Client类的实现：

package SocketS;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.PrintWriter;
import java.net.Socket;
import java.util.Scanner;

import org.apache.log4j.Logger;

import com.sun.security.ntlm.Client;

import User.Users;
import User.UsersDao;

/**
 * 客户端调用登录/注册 后绑定用户操作
 * 
 * @author Administrator
 *
 */
public class Cilent {

 public static void main(String[] args) {
 try {
  Socket socket = new Socket("127.0.0.1", 11536);
  Menu(socket);
 } catch (IOException e) {
  e.printStackTrace();
 }
 }

 private static void Menu(Socket socket) throws IOException {
 Scanner sc = new Scanner(System.in);
 PrintWriter printwriter = null;
 OutputStream outputStream = null;
 BufferedReader bufferedReader = null;
 String choice;
 do {
  System.out.println("请您选择：1.老用户立即登录   2.新用户注册即玩\n" + "请输入正确的数,输入0退出系统");
  choice = sc.next();
  System.out.println(choice);
  // 先传入玩家的操作选项
  
  if (Integer.parseInt(choice) > 0 && Integer.parseInt(choice) < 3) {
  outputStream = socket.getOutputStream();
  byte[] by = choice.getBytes();
  outputStream.write(by, 0, by.length);
  outputStream.flush();
//  socket.shutdownOutput();
  }
  printwriter = new PrintWriter(outputStream);
  
  bufferedReader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
  System.out.println(bufferedReader.readLine());
  switch (choice) {
  case "0":
  System.exit(0);
  break;
  case "1":
  ClientLogin(printwriter,sc);
  
  break;
  case "2":
  ClientRegist(printwriter);// 注册
  ClientLogin(printwriter,sc);
  
  break;
  }
 } while (Integer.parseInt(choice) > 3 || Integer.parseInt(choice) < 1);
 
 
 while (true) {
  //登录完成！
  //获取服务器传来的消息！
  System.out.println("请选择：1.单抽过过瘾！2.10连抽任性 0.退出");
  String choiceCards = sc.next();
  if ("0".equals(choiceCards)) {
  socket.close();
  System.exit(0);
  }
  
  printwriter.println(choiceCards);
  printwriter.flush();
  String str = bufferedReader.readLine();
  Logger logger = Logger.getLogger(Client.class);
  logger.info(str);
  System.out.println(str);
 }
 
 }

 /**
 * 客户端用户注册//注册，并将对象通过对象写出到网络流中
 * 
 * @param socket
 * @throws IOException
 */
 private static void ClientRegist(PrintWriter printwriter) throws IOException {
 UsersDao uersDao = new UsersDao();
 Users u = uersDao.UserRegister();
 printwriter.println(u);
 printwriter.flush();
// socket.shutdownOutput();
 }
 
 private static void ClientLogin(PrintWriter printwriter,Scanner sc){
 String name = null;
 int age = 0 ;
 while (true) {
  try {
  System.out.println("请输入昵称");
  name = sc.next();
  System.out.println("请输入年龄");
  age = sc.nextInt();
  break;
  } catch (Exception e) {
  System.err.println("您的输入不合法，请重新输入");
  e.printStackTrace();
  } 
 }
 String checkstr = "Name="+name+"：Age="+age;
 
 //将字符串传入网络流后对服务器的文件进行判断
 printwriter.println(checkstr);
 printwriter.flush();
 }

}

Server端（多线程）

package SocketS;

import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;

/**
 * 服务器   需要完成登录校验 ，注册校验 以及游戏抽卡
 * @author Administrator
 *
 */
public class Server implements Runnable {
 Socket socket = null;
 
 public Server(Socket socket) {
 super();
 this.socket = socket;
 }

 @Override
 public void run() {
 ServerDao serverDao = new ServerDao();
 try {
  serverDao.Menu(socket);
 } catch (ClassNotFoundException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
 } catch (IOException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
 }
 }

 public static void main(String[] args) {
 ServerSocket serverSocket = null;
 Socket socket = null;
 try {
  serverSocket = new ServerSocket(11536);
 } catch (IOException e1) {
  e1.printStackTrace();
 }
 try {
  while (true) {
  
  socket = serverSocket.accept();
  new Thread(new Server(socket)).start();
  }
 } catch (IOException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
 }
 }
}

ServerDao

package SocketS;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileOutputStream;
import java.io.FileReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.PrintWriter;
import java.net.Socket;
import java.util.Scanner;

import Cards.Cards;
import Cards.CardsDao;
import User.UsersDao;

/**
 * 服务的操作
 * 
 * @author Administrator
 *
 */
public class ServerDao {
 UsersDao ud = new UsersDao();
 File file = new File("D:\\Users.txt");

 /**
 * 服务器接收Client发来的注册信息。并且将用户信息保存到文件中
 * 暗
 * @param socket
 * @return
 * @throws IOException
 * @throws ClassNotFoundException
 */
 public boolean isRegistCheck(Scanner sc) throws IOException, ClassNotFoundException {
 String userStr = getObjectFromSocket(sc);
 // 将读取的User对象写入文件中
 PrintWriter printWriter = new PrintWriter(new FileOutputStream(file,true));
 printWriter.println(userStr);
 printWriter.flush();
 return true;
 }

 /**
 * 检查登录信息是否正确 ,未完成！！！
 * 
 * @param socket
 * @return 返回登录信息是否正确
 * @throws IOException
 * @throws ClassNotFoundException
 */
 public boolean isLoginCheck(Scanner sc) throws IOException, ClassNotFoundException {
 String userStr = getObjectFromSocket(sc);
 BufferedReader bufferedReader = new BufferedReader(new FileReader(file));
 String str = bufferedReader.readLine();
 while (str != null) {
  if (str.contains(userStr)) {
  return true;
  }
  str = bufferedReader.readLine();
 }
 return false;
 }

 /**
 * 获取客户端提供的Users对象
 * @param socket 传入的对应客户端网络套接字
 * @param reader 已经包装的BufferedReader 类获取了网络输入流
 * @return 返回Users对象
 * @throws IOException
 * @throws ClassNotFoundException
 */
 private String getObjectFromSocket(Scanner sc) throws IOException, ClassNotFoundException {
 // 读取网络流，获取客户端提供的Users对象
 String str = null;
 System.out.println(sc.hasNextLine());
 while (sc.hasNextLine()) {
  str = sc.nextLine();
  return str;
 }
 return str;
 
 }

 private String getCards(String choiceCards, PrintWriter printWriter){
 CardsDao cardsDao = new CardsDao();
 if ("1".equals(choiceCards)) {
  Cards card = cardsDao.once();
  return card.getName();
 }else if ("2".equals(choiceCards)) {//10连
  Cards[] cardsArr = cardsDao.tenTimes();
  StringBuffer sb = new StringBuffer();
  for (int i = 0; i < cardsArr.length; i++) {
  sb.append(cardsArr[i].getName()+" ");
  }
  return sb.toString();
  
 }
 return null;
 }
 
 
 /**
 * 服务器接收用户传来的操作信息提供菜单
 * 
 * @param socket
 * @throws IOException
 * @throws ClassNotFoundException
 */
 public void Menu(Socket socket) throws IOException, ClassNotFoundException {
 // 先处理玩家发来的注册登录选项
 InputStream in = socket.getInputStream();
 Scanner sc = new Scanner(in);
 byte[] by = new byte[10];
 in.read(by, 0, by.length);
 String str = new String(by);
 String str1 = "1";
 String str2 = "2";
 System.out.println(str);
 str =str.trim();
 PrintWriter printWriter = new PrintWriter(socket.getOutputStream());
 
 boolean flag = true;
 if (str1.equals(str)) { // 登录
  printWriter.println("请输入登录信息");
  printWriter.flush();
  flag= isLoginCheck(sc);
 } else if (str2.equals(str)) {// 
  printWriter.println("请输入注册信息");
  printWriter.flush();
  isRegistCheck(sc);
  flag= isLoginCheck(sc);
 }
 
 if (flag) {
  System.out.println("欢迎登录");
 }else {
  System.out.println("请您注册后再登录");
  System.exit(0);
 }
 
 while (true) {
  //获取玩家的选择抽卡方式
  by = new byte[10];
  in.read(by, 0, by.length);
  String choiceCards = new String(by);
  choiceCards = choiceCards.trim();
  //调取抽卡游戏：
   String cardsStr = getCards(choiceCards, printWriter);
   printWriter.println(cardsStr);
   printWriter.flush();
 }
 }

}

抽卡的具体实现（比较简单）

package Cards;

import java.util.Random;

/**
 * 抽卡类  
 * @author Administrator
 *
 */
public class CardsDao {
 
 public Cards once(){
 double d = Math.random();
 if (d>0 && d<=0.01) {
  return new NvWa();
 }else if (d>0.01 && d<=0.1) {
  return new Crafty();
 }else if(d>0.1){
  Random random = new Random();
  switch (random.nextInt(3)) {
  case 0:
  return new HeavenlyHound();
  case 1:
  return new BlackFengHuang();
  case 2:
  return new NineFox();
  default:
  break;
  }
  
 }
 return null;
 } 
 
 public Cards[] tenTimes(){
 Cards[] cardsArr = new Cards[10];
 for (int i = 0; i < cardsArr.length; i++) {
  Cards card = once();
  cardsArr[i] = card;
 }
 return cardsArr;
 }
 
 
}
