2.java main方法调用

}
Q3: 用JAVA怎么写QQ
用java是可以写出qq的，只不过用java开发c/s的软件不是java特长的，你要是真的想写，就写着练练手吧，最起码可以巩固java se上的知识。
具体怎么写，给你个大概的思路吧，因为我没办法在这个有限的输入框内把所有的代码写完。
【1】先写出qq的简单界面
【2】给每个按钮添加监听
【3】按钮事件（方法）定义
【4】连接网络（socket）
【5】测试
【5】其他功能添加
【6】测试
Q4: 有谁知道QQ后台程序用JAVA怎么编写啊?
import java.io.*;
public class QQ_Manager {
private int max_user=1000;
private String[] userID;
private String[] userName;
private String[] userPW;
private String[] userIP;
private int userCounts;
private int userOnline;
private String fileName;
/**构造方法初始化数据文件等*/
QQ_Manager(String fileName){this.fileName=fileName;}
/**将现有的QQ用户和记录写入数据文件*/
public synchronized void write_userDataFile(String fileName) {
}
/**从数据文件中读取QQ用户记录*/
public synchronized void read_userDataFile(String fileName) {
}
/**用户来注册新的QQ号*/
public synchronized boolean regist_QQ(String userName,String PW){return false;}
/**QQ用户登陆处理*/
public synchronized boolean login_QQ(String id,String pw){return true;}
/**QQ用户离线处理*/
public synchronized boolean logout_QQ(String id, String pw){return false;}
/**返回QQ在线列表*/
public String get_QQList(){return null;}
}
Q5: 怎样用java 编写简易qq聊天工具？？？？
首先，学习java GUI编程，学习监听器。建议看马士兵的视频。然后上网上down源代码，分析类，确定类的属性和方法。第一遍，就是跟着源码敲一遍，然后分段看，一段一段的看懂，再实现。慢慢就会了。很有收获滴！ 这是高仿QQ2012登录界面 源代码
