java 代码，练习ip,主机名的获取方法。InetAddress类

package clientFrame;
import java.io.IOException;
import java.net.*;

public class tai {
public static void main(String[] args) throws UnknownHostException  {
InetAddress ia;
ia=InetAddress.getByName("www.sina.com");			//搞笑吧
System.out.println("新浪主机ip是"+ia.getHostAddress());//因为我没联网所以无法获取网址的主机，ip
System.out.println("新浪主机的机名；"+ia.getHostName());
ia=InetAddress.getByName("www.soso.com");
System.out.println("so的ip："+ia.getHostAddress());
System.out.println("so的主机名"+ia.getHostName());

}
}
