Java用socket与awt实现简单对话

客户端

public class RoomClient01 implements ActionListener {
	static TextArea textArea;
	static TextField textField;
	static Button send;
	static String toServer;
	static DataInputStream dataInputStream;
	static DataOutputStream dataOutputStream;
	 Socket socket;
	public RoomClient01(Socket socket) {
		// TODO Auto-generated constructor stub
		this.socket = socket;
	}
	/*
	 * 创建GUI面板
	 */
	public void createUI () throws IOException {
		Frame f = new Frame("客户端");
		textArea = new TextArea();
         textField = new TextField();
         send = new Button("send");
         send.addActionListener(this);
        Panel p = new Panel();
        p.setLayout(new BorderLayout());
        p.add(textField, "Center");
        p.add(send, "East");
        f.add(textArea, "Center");
        f.add(p, "South");
        f.addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent e) {
                System.exit(0);
            }
        });
        f.setSize(400, 400);
        f.setLocation(600, 0);
        f.setVisible(true);
        connect();
}
	/*
	 * 连接服务端并且不断从服务端读取数据
	 */
	
	public void connect() throws IOException {
		dataInputStream = new DataInputStream(socket.getInputStream());
		dataOutputStream = new DataOutputStream(socket.getOutputStream());
		while(true) {
			String string = dataInputStream.readUTF();
			textArea.append("服务>>"+string+"\n");
		}
	}
	/*
	 * 添加点击事件
	 */
	@Override
	public void actionPerformed(ActionEvent e) {
		Object source = e.getSource();
		if (source==send) {
			toServer=textField.getText();
			try {
				textArea.append("客户>>"+toServer+"\n");
				dataOutputStream.writeUTF(toServer);
				dataOutputStream.flush();
			} catch (IOException e1) {
				// TODO Auto-generated catch block
				e1.printStackTrace();
			}
		}
	}
	public static void main(String[] args) throws IOException {
		Socket socket = new Socket("localhost", 5551);
		RoomClient01 roomClient01 = new RoomClient01(socket);
		roomClient01.createUI();
	}

}

服务端

public class RoomServer01 implements ActionListener{
	 static  TextArea textArea;
	 static TextField textField;
	 static String fromclient;
	 static Button send;
	 static DataInputStream dataInputStream;
	 static DataOutputStream dataOutputStream;
	 ServerSocket serverSocket;
	 /*
	  * 创建GUI面板
	  */
	 	public void createUI () throws IOException {
			Frame f = new Frame("服务端");
			textArea = new TextArea();
	         textField = new TextField();
	         send = new Button("send");
	         send.addActionListener(this);
	        Panel p = new Panel();
	        p.setLayout(new BorderLayout());
	        p.add(textField, "Center");
	        p.add(send, "East");
	        f.add(textArea, "Center");
	        f.add(p, "South");
	        f.addWindowListener(new WindowAdapter() {
	            public void windowClosing(WindowEvent e) {
	                System.exit(0);
	            }
	        });
	        f.setSize(400, 400);
	        f.setLocation(600, 0);
	        f.setVisible(true);
	        connect();
	}
	 	public RoomServer01(ServerSocket serverSocket) {
			// TODO Auto-generated constructor stub
	 		this.serverSocket = serverSocket;
		}
	 	/*
	 	 *添加点击事件 
	 	 */
	@Override
	public void actionPerformed(ActionEvent e) {
		Object source = e.getSource();
		if (source==send) {
			String toclient = textField.getText();
			textArea.append("服务>>"+toclient);
					try {
						dataOutputStream.writeUTF(toclient);
						dataOutputStream.flush();
					} catch (IOException e1) {
						// TODO Auto-generated catch block
						e1.printStackTrace();
					}
		}
	}
	/*
	 * 连接客户端并且不断从客户端读取数据
	 */
	public  void connect() throws IOException{
		Socket socket = serverSocket.accept();
		dataInputStream = new DataInputStream(socket.getInputStream());
		dataOutputStream = new DataOutputStream(socket.getOutputStream());
		while(true) {
			String string = dataInputStream.readUTF();

		}
	}
	
	public static void main(String[] args) throws IOException {
		ServerSocket serverSocket = new ServerSocket(5551);
		RoomServer01 roomServer01 = new RoomServer01(serverSocket);
		roomServer01.createUI();
	}
