simpleserver.java

java开发的网络方面的原代码例子

  //SimpleServer.java
  import java.net.*;
  import java.io.*; 
  
  public class SimpleServer { 
  public static void main(String args[]) { 
  ServerSocket s = null; 
  Socket s1; 
  String sendString = "Hello Net World!"; 
  OutputStream s1out; 
  DataOutputStream dos; 
  
  // 在5432端口启动服务 
  try { 
  s = new ServerSocket(5432); 
  } catch (IOException e) { } 
  
  //循环监听连接
  while (true) { 
  try { 
  // 等待连接
  s1=s.accept(); 
  
  // 得到通讯的数据流
  s1out = s1.getOutputStream(); 
  dos = new DataOutputStream (s1out); 
  
  // 发送数据 
  dos.writeUTF(sendString); 
  
  // 关闭连接
  s1out.close(); 
  s1.close(); 
  } catch (IOException e) { } 
  } 
  } 
  }
