Creating a Strong Password Checker | JAVA INTERVIEW QUESTIONS

In this in-depth tutorial, we tackle a commonly encountered Java technical interview question: creating a strong password validator. This video guides you through the process of writing a program that determines whether a given password is strong or not, based on a set of predefined requirements.

These requirements include the password being at least eight characters long, containing at least one uppercase letter, one lowercase letter, a digit, and a special character, all while ensuring that there are no white spaces. If a password does not meet these requirements, it is categorized as weak or invalid.

Throughout the video, we break down each step of the task, beginning with checking for white spaces and invalid characters. Then, we shift our focus towards checking whether the password meets the 'strong' criteria. The video provides a thorough walkthrough of the coding process, with a clear explanation of each line of code and its role in the overall program.

This tutorial is perfect for those preparing for a Java programming interview, or those who simply want to improve their understanding and abilities in Java. By following along, you'll gain a better understanding of how to validate user input in a real-world context.

Remember to test the program with different passwords to ensure its reliability.
