用JAVA写一个客户端和服务端可以连接，客户端和服务端都具有页面组件，如文本域，流动条，面板，文本框,俩个按钮b1,b2.b1可以分别在客户端和服务端发信息聊天，b2可以发送图片

好的，我会给出一个简单的示例代码，帮助您实现这个功能。 首先是服务端的代码： ```java import java.io.*; import java.net.*; import javax.swing.*; import java.awt.*; import java.awt.event.*; public class Server extends JFrame implements ActionListener { private JTextField textField; private JTextArea textArea; private JButton button1, button2; private ServerSocket serverSocket; private Socket clientSocket; private PrintWriter out; private BufferedReader in; public Server() { super("Server"); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setSize(400, 400); textField = new JTextField(20); button1 = new JButton("Send"); button2 = new JButton("Send Image"); button1.addActionListener(this); button2.addActionListener(this); JPanel panel = new JPanel(); panel.setLayout(new FlowLayout()); panel.add(textField); panel.add(button1); panel.add(button2); textArea = new JTextArea(); textArea.setEditable(false); JScrollPane scrollPane = new JScrollPane(textArea); getContentPane().add(scrollPane, BorderLayout.CENTER); getContentPane().add(panel, BorderLayout.SOUTH); setVisible(true); try { serverSocket = new ServerSocket(12345); textArea.append("Server started.\n"); clientSocket = serverSocket.accept(); textArea.append("Client connected.\n"); out = new PrintWriter(clientSocket.getOutputStream(), true); in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream())); String inputLine; while ((inputLine = in.readLine()) != null) { textArea.append("Client: " + inputLine + "\n"); } in.close(); out.close(); clientSocket.close(); serverSocket.close(); } catch (IOException e) { System.out.println("Exception caught when trying to listen on port or listening for a connection"); System.out.println(e.getMessage()); } } public void actionPerformed(ActionEvent e) { if (e.getSource() == button1) { String message = textField.getText(); out.println(message); textArea.append("Server: " + message + "\n"); textField.setText(""); } else if (e.getSource() == button2) { // TODO: send image } } public static void main(String[] args) { new Server(); } } ``` 然后是客户端的代码： ```java import java.io.*; import java.net.*; import javax.swing.*; import java.awt.*; import java.awt.event.*; public class Client extends JFrame implements ActionListener { private JTextField textField; private JTextArea textArea; private JButton button1, button2; private Socket socket; private PrintWriter out; private BufferedReader in; public Client() { super("Client"); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setSize(400, 400); textField = new JTextField(20); button1 = new JButton("Send"); button2 = new JButton("Send Image"); button1.addActionListener(this); button2.addActionListener(this); JPanel panel = new JPanel(); panel.setLayout(new FlowLayout()); panel.add(textField); panel.add(button1); panel.add(button2); textArea = new JTextArea(); textArea.setEditable(false); JScrollPane scrollPane = new JScrollPane(textArea); getContentPane().add(scrollPane, BorderLayout.CENTER); getContentPane().add(panel, BorderLayout.SOUTH); setVisible(true); try { socket = new Socket("localhost", 12345); out = new PrintWriter(socket.getOutputStream(), true); in = new BufferedReader(new InputStreamReader(socket.getInputStream())); String inputLine; while ((inputLine = in.readLine()) != null) { textArea.append("Server: " + inputLine + "\n"); } in.close(); out.close(); socket.close(); } catch (IOException e) { System.out.println("Exception caught when trying to connect to the server"); System.out.println(e.getMessage()); } } public void actionPerformed(ActionEvent e) { if (e.getSource() == button1) { String message = textField.getText(); out.println(message); textArea.append("Client: " + message + "\n"); textField.setText(""); } else if (e.getSource() == button2) { // TODO: send image } } public static void main(String[] args) { new Client(); } } ``` 这里还没有实现发送图片的功能，您可以参考Java的ImageIO类来实现。希望这个示例代码对您有所帮助！
