JAVA編寫(xiě)服務(wù)器和客戶端.docx

1、服務(wù)器程序代碼如下：import java.io.*;import .*;import java.awt.*;import java.awt.event.*;public class aaa extends Frame implements ActionListener Label label = new Label(交談內(nèi)容); Panel panel = new Panel(); TextField tf = new TextField(10); TextArea ta = new TextArea(); ServerSocket server; Socket client; InputStream in; OutputStream out; public aaa() super(服務(wù)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 ServerSocket(4000); client = server.accept(); ta.append(客戶機(jī)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(服務(wù)器端： + str + nn); 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(： + str + n); catch (IOException ioe) public static void main(String args) new aaa(); 運(yùn)行結(jié)果：2、客戶端程序代碼如下：import java.io.*;import .*;import java.awt.*;import java.awt.event.*;public class client extends Frame implements ActionListener Label label = new Label(交談內(nèi)容); Panel panel = new Panel(); TextField tf = new TextField(10); TextArea ta = new TextArea(); Socket client; InputStream in; OutputStream out; public client() super(客戶端); setSize(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(您服務(wù)器是： + 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(服務(wù)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.a
