Parsing a URL in Java is straightforward with the URL class provided in the java.net package. Here's a step-by-step guide on how to do it:

1. Importing the URL Class

import java.net.URL;

2. Creating a URL Object

URL url = new URL("https://example.com/path?name=value#hash");

3. Accessing URL Components

System.out.println(url.getProtocol());  // Output: https
System.out.println(url.getHost());      // Output: example.com
System.out.println(url.getPath());      // Output: /path
System.out.println(url.getQuery());     // Output: name=value
System.out.println(url.getRef());       // Output: hash

4. Working with URL Parameters

import java.util.Map;
import java.util.Scanner;

// Split the query string into a map of parameters
String query = url.getQuery();
Map<String, String> params = new Scanner(query.replace("&", "\n")).useDelimiter("=").tokens()
    .collect(Collectors.toMap(token -> token, token -> new Scanner(token).next()));

System.out.println(params);  // Output: {name=value}

5. Modifying and Reconstructing URLs

import java.net.URI;

// Create a new URI with modified components
URI newUri = new URI(url.getProtocol(), null, url.getHost(), url.getPort(), "/newpath", url.getQuery(), url.getRef());
URL newUrl = newUri.toURL();

System.out.println(newUrl);  // Output: https://example.com/newpath?name=value#hash

With the URL and URI classes, parsing a URL in Java is simple, allowing you to access, analyze, and modify URLs with ease.
