顯示IP

通過JAVA API顯示本機IP地址和網絡上任何一臺可以訪問到的服務器的IP地址

  

import java.io.IOException;

import java.net.InetAddress;

import java.net.UnknownHostException;

public class GetIP {

    private InetAddress LocalIP=null;

    private InetAddress ServerIP=null;

   

    public static void main(String args[]){

        GetIP mytest=new GetIP();

        System.out.println("LocalHost IP is :" + mytest.catchLocalIP() );

        System.out.println("Server IP is :" + mytest.catchServerIP() );

    }

    //取得本機IP地址

    public InetAddress catchLocalIP(){

        try{

            LocalIP=InetAddress.getLocalHost();

        }

        catch(UnknownHostException e){

        }

        return LocalIP;

    }

   

    //取得服務器網絡地址

    public InetAddress catchServerIP(){

        try{

            ServerIP=InetAddress.getByName("www.baidu.com");//取得IP 地址

        }

        catch(UnknownHostException e){

            return ServerIP;

        }

        return ServerIP;

    }

}

 輸出：

LocalHost IP is :SCOM2987/10.120.0.54
Server IP is :www.baidu.com/220.181.6.175
