1、1、服务器程序代码如下：import java.io.*;import .*;import java.awt.*;import java.awt.event.*;public class aaa extends Frame implements ActionListener Label label = new Label(交谈内容); Panel panel = new Panel(); TextField tf = new TextField(10); TextArea ta = new TextArea(); ServerSocket server; Socket client; Inpu
2、tStream in; OutputStream out; public aaa() super(服务器); setSize(80, 80); panel.add(label); panel.add(tf); tf.addActionListener(this); add(West, panel); add(Center, ta); addWindowListener(new WindowAdapter() public void windowClosing(WindowEvent e) System.exit(0); ); show(); try server = new ServerSoc
3、ket(4000); client = server.accept(); ta.append(客户机端： + client.getInetAddress().getHostName() + nn); in =client.getInputStream(); out= client.getOutputStream(); catch (IOException ioe) while (true) try byte buf = new byte256; in.read(buf); String str = new String(buf); ta.append(服务器端： + str + nn); ca
4、tch (IOException e) public void actionPerformed(ActionEvent e) try String str = tf.getText(); byte buf = str.getBytes(); tf.setText(null); out.write(buf); ta.append(： + str + n); catch (IOException ioe) public static void main(String args) new aaa(); 运行结果：2、客户端程序代码如下：import java.io.*;import .*;impor
5、t java.awt.*;import java.awt.event.*;public class client extends Frame implements ActionListener Label label = new Label(交谈内容); Panel panel = new Panel(); TextField tf = new TextField(10); TextArea ta = new TextArea(); Socket client; InputStream in; OutputStream out; public client() super(客户端); setS
6、ize(250, 250); panel.add(label); panel.add(tf); tf.addActionListener(this); add(West, panel); add(Center, ta); addWindowListener(new WindowAdapter() public void windowClosing(WindowEvent e) System.exit(0); ); show(); try client = new Socket(InetAddress.getLocalHost(), 4000); ta.append(您服务器是： + clien
7、t.getInetAddress().getHostName() + nn); in = client.getInputStream(); out = client.getOutputStream(); catch (IOException ioe) while (true) try byte buf = new byte256; in.read(buf); String str = new String(buf); ta.append(服务器端： + str + n); catch (IOException e) public void actionPerformed(ActionEvent e) try String str = tf.getText(); byte buf = str.getBytes(); tf.setText(null); out.write(buf); ta.append(客户端： + str + n); catch (IOException iOE) public static void main(String args) new client(); 运行结果：最后输入信息，如：你好吗？
