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;

File file = new File("D:\\Users.txt");
/**

* 暗
* @param socket
* @return
* @throws IOException

*/
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！！！
*

*/
public boolean isLoginCheck(Scanner sc) throws IOException, ClassNotFoundException {

}
return false;
}
/**

* @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;
}
}
