本篇文章给大家分享的是有关利用JAVASE系统怎么实现一个抽卡功能，小编觉得挺实用的，因此分享给大家学习，希望大家阅读完这篇文章后可以有所收获，话不多说，跟着小编一起来看看吧。
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;
/**

* @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);
}
}
/**

*/
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");

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）

return str;
}
return str;
}
private String getCards(String choiceCards, PrintWriter printWriter){

if ("1".equals(choiceCards)) {

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;
}
/**

*/
public void Menu(Socket socket) throws IOException, ClassNotFoundException {
// 先处理玩家发来的注册登录选项

//调取抽卡游戏：
String cardsStr = getCards(choiceCards, printWriter);

}抽卡的具体实现（比较简单）
package Cards;
import java.util.Random;
/**

*
*/
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;
}
