In this episode, we break down one of the most common and frustrating errors in Java—NullPointerException (NPE). Learn what it is, why it occurs, and how to prevent it using best practices like proper null checks, the Optional class, defensive programming, and modern Java features. We’ll also cover real-world debugging tips and explain how to design code that avoids null-related bugs. Whether you're new to Java or preparing for interviews, this episode will help you write safer and more reliable code.
