First Assignment - RegEx

Enough of algorithms! Let's dive into a practical development tool called RegEx (Regular Expressions).

What is RegEx?

RegEx is short for Regular Expressions. It is used to detect or validate specific patterns within a string, helping us find substrings that match a desired format.

Imagine developing a website and designing a sign-up page. You’ll want to check whether the email entered by the user is valid. What about the password? Or perhaps you need to scan all incoming traffic to detect profanity or sensitive information?

With RegEx, all of this becomes easy and efficient! It saves developers time and improves performance by eliminating unnecessary conditional checks.

Getting Started

Now that you know the power of RegEx, let's begin!

Follow the same structured approach as in the previous assignments:

1. Research and learn about regular expressions, their syntax, and formats.
2. Complete the code by following the provided descriptions.
3. Pass all tests in the test/java folder.
4. Add your mentor as a collaborator to your repo so they can review your work.

Notes

• Each method in Exercises.java has a different return type, so be mindful of your implementation.
• RegEx syntax can vary across different engines—make sure to learn how Java's RegEx works specifically.
