### 一、程序设计方面的说明 ###

**程序分为三个类：**

*  ChatFrame类
 *  ChatClientAPP类
 *  ChatServerAPP类

### 二、各个类介绍 ###

**1、ChatFrame类**

package com.chat;
    
    import java.awt.BorderLayout;
    
    import javax.swing.JButton;
    import javax.swing.JFrame;
    import javax.swing.JPanel;
    import javax.swing.JScrollPane;
    import javax.swing.JTextArea;
    import javax.swing.JTextField;
    
    public class ChatFrame extends JFrame{
        
    	private static final long serialVersionUID = -499796932332494480L;
    	public JTextArea jta;
    	public JScrollPane jsp;
    	public JPanel jp;
    	public JTextField jtf;
    	public JButton jb;
    	public String title;
    	
    	public ChatFrame(String title){
        
    		this.title = title;
    		jta = new JTextArea();
    		jta.setEditable(false);
    		jsp = new JScrollPane(jta);
    		jp = new JPanel();
    		jtf = new JTextField(10);
    		jb = new JButton("发送");
    		jp.add(jtf);
    		jp.add(jb);
    		this.add(jsp, BorderLayout.CENTER);
    		this.add(jp, BorderLayout.SOUTH);
    		this.setTitle(title);
    		this.setSize(300, 300);
    		this.setLocation(500, 300);
    		this.setLocationRelativeTo(null);
    		this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    		this.setVisible(true);
    	}
    }

**2、ChatClientAPP类**  
客户端类

package com.chat;
    
    import java.awt.event.ActionEvent;
    import java.awt.event.ActionListener;
    import java.awt.event.KeyEvent;
    import java.awt.event.KeyListener;

    import java.text.SimpleDateFormat;
    import java.util.Date;
    
    import javax.swing.JTextArea;
    import javax.swing.JTextField;
    import javax.swing.UIManager;
    
    public class ChatClientAPP implements ActionListener, KeyListener {
        
    	public static void main(String[] args) throws Exception {
        
    		UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
    		new ChatClientAPP(new ChatFrame("繁星聊天客户端"));
    	}
    
    	private BufferedWriter bh = null;
    	private JTextField jtf;
    	private JTextArea jta;
    	public ChatClientAPP(ChatFrame chatFrame) {
        
    		this.jtf = chatFrame.jtf;
    		this.jta = chatFrame.jta;
    		chatFrame.jb.addActionListener(this);
    		jtf.addKeyListener(this);
    		try {
        
    			Socket Socket = new Socket("127.0.0.1", 8888);
    
    			// InputStream in=Socket.getInputStream();
    			BufferedReader br = new BufferedReader(new InputStreamReader(Socket.getInputStream()));
    			bh = new BufferedWriter(new OutputStreamWriter(Socket.getOutputStream()));
    			String line = null;
    			Date sb = new Date();
    			SimpleDateFormat sdf = new SimpleDateFormat();
    			sdf.format(sb);
    			jta.append("\t" + sdf.format(sb) + "\n");
    			while ((line = br.readLine()) != null) {
        
    				jta.append(line + System.lineSeparator());
    			}
    			Socket.close();
    
    		} catch (Exception e) {
        
    			e.printStackTrace();
    		}
    
    	}
    
    	@Override
    	public void actionPerformed(ActionEvent e) {
        
    		wdw();
    	}
    
    	// 定义一个方法
    	private void wdw() {
        
    		String text = jtf.getText();
    		text = "客户端对服务端说：" + text;
    		jta.append(text + System.lineSeparator());
    		try {
        
    			bh.write(text);
    			bh.newLine();
    			bh.flush();
    			jtf.setText("");
    		} catch (IOException e1) {
        
    			e1.printStackTrace();
    		}
    	}
    
    	@Override
    	public void keyPressed(KeyEvent e) {
        
    		if (e.getKeyCode() == KeyEvent.VK_ENTER) {
        
    			wdw();
    		}
    	}
    
    	@Override
    	public void keyTyped(KeyEvent e) {
        
    	}
    
    	@Override
    	public void keyReleased(KeyEvent e) {
        
    	}

    			}
    			Socket.close();
    
    		} catch (Exception e) {
        
    			e.printStackTrace();
    		}
    
    	}
