L39: Assertions in java | debugging, validation & runtime checks

Welcome to Lecture 39 of the course "Programming Concepts using Java" by Prof. Madhavan Mukund. Full Course: https://study.iitm.ac.in/ds/course_pages/BSCS2005.html Video Overview This lecture explores the role of assertions in Java as a tool for debugging and validation. We discuss how assertions differ from exceptions, emphasizing that they are intended for internal checks during development rather than for handling user-facing errors. The lecture explains how to enable or disable assertions at runtime, balancing performance with safety, and introduces the idea of system assertions for consistent validation across programs. By the end, you’ll understand how assertions can help improve code quality, catch logical errors early, and complement other error-handling mechanisms in Java.
