Socket通信客户端设计（Java）

public class Client extends JFrame implements Runnable{

    private JPanel jPanel= new JPanel();
    private JLabel jLabel1=new JLabel("姓名： ");
    private JLabel jLabel2=new JLabel("端口： ");
    private JTextField jTextField1=new JTextField();
    private JTextField jTextField2=new JTextField();
    private JTextArea jTextArea=new JTextArea();
    private JTextField jTextField3=new JTextField();
    private JButton jButton=new JButton("发送(S)");
    
    private JScrollPane jScrollPane=new JScrollPane();
    private BufferedReader bufferedReader;
    private PrintWriter printWriter;
    private Socket socket;
    
    private static String title="劲爆聊天室";
    
    public Client(String port,String name){
        super(title+":"+name);
        this.setSize(377,387);
        this.add(jPanel);
        jPanel.setLayout(null);
        jTextArea.setEditable(false);
        //
        jPanel.add(jLabel1);
        jLabel1.setBounds(10, 10, 60, 20);
        jTextField1.setText(name);
        jTextField1.setEditable(false);
        jPanel.add(jTextField1);        
        jTextField1.setBounds(60, 10, 60, 21);
        
        jPanel.add(jLabel2);
        jLabel2.setBounds(125, 10, 60, 20);
        jTextField2.setText(port);
        jTextField2.setEditable(false);
        jPanel.add(jTextField2);
        jTextField2.setBounds(190, 10, 60, 21);;
        
        jPanel.add(jTextField3);
        jTextField3.setBounds(10, 270, 320, 21);
        
        jTextArea.setColumns(20);
        jTextArea.setRows(5);
        
        jTextArea.setEditable(false);
        jScrollPane.setViewportView(jTextArea);
        jPanel.add(jScrollPane);
        jScrollPane.setBounds(10, 42, 320, 220);
        
        jPanel.add(jButton);
        jButton.setBounds(250, 300, 80, 22);
        jButton.addActionListener(new ActionListener() {
            
            @Override
            public void actionPerformed(ActionEvent e) {
                // TODO Auto-generated method stub
                if(e.getSource()==jButton){
                    printWriter.println(jTextField1.getText()+": "+jTextField3.getText());
                    jTextField3.setText("");
                }
            }
        });
        //Jtextfield不好控制啊。。。。
/*        jTextField3.addActionListener(new ActionListener() {
            
            @Override
            public void actionPerformed(ActionEvent e) {
                // TODO Auto-generated method stub
                printWriter.println(jTextField1.getText()+":"+jTextField3.getText());
                jTextField3.setText("");
            }
        });*/
        getSocket();
    }
    @Override
    public void run(){
        while(true)
        {
            try {
                jTextArea.append(bufferedReader.readLine()+"
");
                
            } catch (Exception e) {
                // TODO: handle exception
                e.printStackTrace();
            }
        }
    }
    
    public void getSocket(){
        jTextArea.append("正在与劲爆聊天室进行连接..."+"
");
        try {
            socket=new Socket("127.0.0.1",PortNumber.PORT.getNumber());
            jTextArea.append("劲爆聊天开始..."+"
");
            bufferedReader=new BufferedReader(new InputStreamReader(socket.getInputStream()));
            printWriter=new PrintWriter(socket.getOutputStream(),true);
            new Thread(this).start();
        } catch (Exception e) {
            // TODO: handle exception
            e.printStackTrace();
        }
    }
    
}

考虑到多客户端，此处用到了多线程。Socket确实有意思....

非常感叹T公司如果把一个IM软件，做到亿级用户量，如何解决并发，如何解决Server的及时回应，如何完成数据存储...

想不出来了...
