private void reset(ActionEvent e)

userName.setText(null);

serverAddress.setText(null);

new LoginConnection(userName.getText(), serverAddress.getText(),

public Login(String name)

super(name);

this.init();

public static void main(String[] args)

public class LoginConnection extends Thread

private Login login;

private InputStream is;

private OutputStream os;

private Chatting chatting;

private Socket socket;

//LoginConnection 的构造方法, 在此构造方法中, 调用本类的 connect2Server()方法,

如果成功连接, 则继续调用 login()方法, 与主机进行相关交互.具体查看 login()方法注释.

public LoginConnection(String userName, String serverAddress, int port, Login

login)

this.serverAddress = serverAddress;

try {

this.socket = new Socket(serverAddress, port);

is = socket.getInputStream();

os = socket.getOutputStream();

} catch (Exception e) {

JOptionPane.showMessageDialog(login, "服务器可能还没启动, 请确定服

务器正常", "无法连接到服务器", JOptionPane.ERROR_MESSAGE);

return false;

}
