net.java

这是一个用java编写的关于WEB应用编程的简单的聊天系统的样例

package intnet;

import java.net.*;
public class Net {
public static void main (String args[])  {
    InetAddress myIP = null; //声明IP地址对象变量
    try	{
        myIP = InetAddress.getLocalHost(); //获得本级IP地址
        //下面的语句显示了获得指定主机名的IP地址的方法
        //myIP = InetAddress.getByName("java.sun.com"); 
        System.out.println("HostAddress is "+myIP.getHostAddress());
        System.out.println("HostName is "+myIP.getHostName());
     }catch(UnknownHostException e){
             //忽略异常
     }
}
}
