How to Get URL Properties in Java

In this example, we will obtain many ways to get properties of a URL object, such as getProtocol(), getHost(), getPort(), getQuery(), getRef(), and so on.

Source Code

package com.beginner.examples;

import java.net.URL;

public class GetURLProperties {

	public static void main(String[] args) {

		//Indicates a URL reference
		URL url = null;
		try {
			//Assign a value to this reference
			url = new URL("http://www.google.cn:80?query=ok#header");
		} catch (Exception e) {

			e.printStackTrace();
		}

		//Get some properties of the URL
		String protocol = url.getProtocol();

		String host = url.getHost();

		int port = url.getPort();

		String query = url.getQuery();

		String reference = url.getRef();

		System.out.println("Protocol: " + protocol +
							"nHost: " + host + 
							"nPort: " + port + 
							"nQuery: " + query +
							"nReference: " + reference);
	}

}

Output:

Protocol: http
Host: www.google.cn
Port: 80
Query: query=ok
Reference: header
