服务器端package com.robert.view; import java.io.BufferedInputStream; import java.io.DataInputStream; import java.io.IOException; import java.io.InputStream; import java.net.ServerSocket; import java.net.Socket; public class ServerClient { public static void main(String[] args) { ServerSocket server = null; Socket socket = null; InputStream inputStream = null; BufferedInputStream bis = null; DataInputStream dis = null; try { server = new ServerSocket(10000); socket = server.accept(); inputStream = socket.getInputStream(); bis = new BufferedInputStream(inputStream); dis = new DataInputStream(bis); System.out.println(dis.readUTF()); } catch (IOException e) { e.printStackTrace(); }finally { try { inputStream.close(); } catch (IOException e) { e.printStackTrace(); } } } }

客户端

package com.robert.view; import java.io.BufferedOutputStream; import java.io.DataOutputStream; import java.io.IOException; import java.io.OutputStream; import java.net.Socket; import java.net.UnknownHostException; public class CustomerClient { public static void main(String[] args) { OutputStream outputStream = null; BufferedOutputStream bos = null; DataOutputStream dos = null; try { Socket socket = new Socket("localhost",10000); outputStream = socket.getOutputStream(); bos = new BufferedOutputStream(outputStream); dos = new DataOutputStream(bos); dos.writeUTF("hello world"); dos.flush(); } catch (UnknownHostException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); }finally { try { outputStream.close(); } catch (IOException e) { e.printStackTrace(); } } } }
