L37: Exceptions in java | try-catch, custom exceptions, finally & robust code

Welcome to Lecture 37 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 takes a closer look at exception handling in Java, exploring its hierarchy and practical use in building reliable applications. We distinguish between Errors, RuntimeExceptions, and checked Exceptions, explaining when and why each type arises. The lecture demonstrates how to write effective try-catch blocks, create custom exception classes, and chain exceptions to capture detailed information about errors. We also study the finally block, showing how it ensures critical code executes regardless of whether an exception occurs. By the end, you will understand how mastering exception handling leads to stronger, more maintainable, and robust Java programs.
