Introduction
In Java, URL validation is commonly required in web applications and data processing. The java.util.regex package in Java provides the functionality for regex-based URL validation.
URL Regex
Java regex for URL validation typically includes the protocol, domain, and optional path.
The URL Regex Pattern
Pattern:
https?://(?:www\\.)?[a-zA-Z0-9./]+This regex pattern supports HTTP and HTTPS and optional 'www.'.
How to Validate URLs in Java?
To perform URL validation in Java:
import java.util.regex.*;
public class URLValidator {
public static boolean isValidURL(String url) {
String regex = "https?://(?:www\\.)?[a-zA-Z0-9./]+";
Pattern pattern = Pattern.compile(regex);
Matcher matcher = pattern.matcher(url);
return matcher.matches();
}
public static void main(String[] args) {
String url = "https://www.example.com";
System.out.println("Is URL valid? " + isValidURL(url));
}
}Uses of URL Regex Validation
Web Applications: Validating URLs in user input, such as form submissions or URL parameters.
Data Validation: Ensuring the correctness of URLs in datasets, crucial for data integrity.
