How To Get URL Properties in Java


Description:

The URL class provides utility methods that let you query URL objects. You can get the protocol, authority, host name, port number, path, query, filename, and reference from a URL using these accessor methods:

getProtocol() method returns the protocol identifier of the URL.
getAuthority() method returns the authority of the URL.
getHost() method returns the host name of the URL.
getPort() method returns the port number of the URL. If the port is not set, then it returns -1.
getPath() method returns the path of this URL.
getQuery() method returns the query of this URL.
getFile() method returns the filename of the URL.
getRef() method returns the reference of the URL.


Code:
package com.myjava.url;

import java.net.MalformedURLException;
import java.net.URL;

public class MyUrlProperties {

    public static void main(String a[]){
    
        try {
            String url =
		"http://www.java2novice.com:80/java_constructor_examples/?query=ok#header";
            URL myUrl = new URL(url);
            System.out.println("Protocol: "+myUrl.getProtocol());
            System.out.println("Host: "+myUrl.getHost());
            System.out.println("Port: "+myUrl.getPort());
            System.out.println("Athority of the URL: "+myUrl.getAuthority());
            System.out.println("Query: "+myUrl.getQuery());
            System.out.println("Reference: "+myUrl.getRef());
        } catch (MalformedURLException ex) {
            ex.printStackTrace();
        }
    }
}

Example Output

Protocol: http
Host: www.java2novice.com
Port: 80
Athority of the URL: www.java2novice.com:80
Query: query=ok
Reference: header

What is adapter class?
An adapter class provides the default implementation of all methods in an event listener interface. Adapter classes are very useful when you want to process only few of the events that are handled by a particular event listener interface. You can define a new class by extending one of the adapter classes and implement only those events relevant to you.
Famous Quotations
The pessimist complains about the wind; the optimist expects it to change; the realist adjusts the sails.
