利用Java获取本地IP地址

package new_world1;
import java.io.;
import java.net.;
//获取IP地址
public class spurs_ping145 {
public static void main(String[] args) throws IOException {
// TODO Auto-generated method stub
if(args.length>0)
{
String host=args[0];
InetAddress[] address=InetAddress.getAllByName(host);
for(InetAddress a : address)
{
System.out.println(a);
}
}
else
{
InetAddress localHostAddress=InetAddress.getLocalHost();
System.out.println(localHostAddress);
}
}
}
