nettool.java

用java写的可以提取你的主机名和ip地址和MAC地址

import java.net.*; 
public class NetTool{ 
InetAddress myIPaddress=null; 
InetAddress myServer=null; 
InetAddress myHostname=null;

public static void main( String args[]){ 

NetTool mytool; 
mytool=new NetTool(); 
/*try {
	String   serverName   =   java.net.InetAddress.getLocalHost().getHostName();
} catch (UnknownHostException e) {
	// TODO Auto-generated catch block
	e.printStackTrace();
}  */ 
System.out.println("Your host IP is: " + mytool.getMyIP()); 
//System.out.println("The Server IP is :" +mytool.getServerIP()); 
try {
	System.out.println("Your host Name is: " + java.net.InetAddress.getLocalHost().getHostName());
} catch (UnknownHostException e) {
	// TODO Auto-generated catch block
	e.printStackTrace();
} 
} 

//取得LOCALHOST的IP地址 
public InetAddress getMyIP() { 
try { myIPaddress=InetAddress.getLocalHost();} 
catch (UnknownHostException e) {} 
return (myIPaddress); 
} 
//取得 www.abc.com 的IP地址 
/*public InetAddress getServerIP(){ 
try {myServer=InetAddress.getByName("www.abc.com");} 
catch (UnknownHostException e) {} 
return (myServer); 
} */
