How to retrieve URL information
Here we are going to explain a method for retrieve all
the network information for a given URL. In the given below example we use the
URL class and make a object. After creating a object we assign a new URL to it.
Then we just call a getProtocol() method to retrieve the protocol, getPort()
method for retrieve the port number of the URL, getHost to get the host name of
that URL. Apart from all of this we can also find out the file name if we pass
any file name with URL by getFile() and by toExternalForm() method is use to
retreive the full name of the URL.
The given example shows all the above method in proper
manner. The code of the example is as under
Here is the Code of the Example :
URLDemo.java
import java.net.*;
public class URLDemo{
public static void main(String args[])throws MalformedURLException{
URL hp = new URL("http://www.javajazzup.com");
System.out.println("Protocal:" + hp.getProtocol());
System.out.println("Port:" + hp.getPort());
System.out.println("Host:" + hp.getHost());
System.out.println("File:" + hp.getFile());
System.out.println("Ext:" + hp.toExternalForm());
}
