URL Parsing

Instructions

Create a class UrlParser that provides a method to parse and validate URLs using regex. The method should extract and return url components the protocol, domain, port, path and query parameters. The URL is always correct.

give back in the map just the existing component.

Expected Class

public class UrlParser {
    public Map<String, String> parseURL(String url) {
        // Implementation to parse and validate URLs using regex
    }
}

Usage

Here is a possible ExerciseRunner.java to test your class:

import java.util.Map;

public class ExerciseRunner {
    public static void main(String[] args) {
        UrlParser parser = new UrlParser();

        // Test case 1
        String url1 = "https://www.example.com:8080/path?name=value";
        Map<String, String> components1 = parser.parseURL(url1);
        System.out.println("Components of URL 1: " + components1);

        // Test case 2
        String url2 = "http://example.com/";
        Map<String, String> components2 = parser.parseURL(url2);
        System.out.println("Components of URL 2: " + components2);

    }
}

Expected Output

$ javac *.java -d build
$ java -cp build ExerciseRunner
Components of URL 1: {protocol=https, domain=www.example.com, port=8080, path=/path, query=name=value}
Components of URL 2: {protocol=http, domain=example.com, path=/}
