Write Cleaner Code by Mastering Exception Handling | DeepRoot with Krish

This is an edited recording of a live training session on Exception Handling in Java. In this session, we cover exception handling in detail. We explore not just the syntax, but also the reasons and best practices behind it. You’ll learn: 🔹 Introduction to Exceptions What exceptions are and why they exist. Exception hierarchy: Throwable, Error, and Exception. The difference between checked and unchecked exceptions. 🔹 Core Exception Handling Mechanisms Using try, catch, and finally blocks effectively. The bubble-up behavior of exceptions in the call stack. Resource cleanup with finally and why it matters. Creating meaningful custom exception classes. 🔹 Checked vs Unchecked Exceptions How Java treats them differently. When to use checked or unchecked exceptions in real projects. Practical examples showing how exceptions propagate and how to handle them. 🔹 Best Practices & Pitfalls Catch the most specific exception possible. Don’t use exceptions for flow control. Avoid empty catch blocks and swallowing exceptions. Why you should never throw exceptions from finally blocks. Logging versus throwing – avoid duplicate logs. Principles like Throw Early, Catch Late. Writing meaningful names for exceptions and custom hierarchies. By the end of this session, you’ll understand how Java exceptions work and how to use them in enterprise-grade applications without creating fragile or hard-to-debug code.
