Confused by Kotlin exceptions? In this video you’ll learn how to handle, throw, and prevent errors like NullPointerException, IllegalArgumentException, and IOException—plus how to read stack traces and design custom exceptions (including sealed hierarchies) the right way.

What you’ll learn
• try/catch/finally (when each makes sense)
• throw vs returning Result/Either
• Common exceptions: NPE, IllegalArg, IllegalState, IO
• Custom exceptions + sealed error models
• Best practices: fail fast, meaningful messages, wrapping causes, logging
• Bonus: avoiding exceptions with null-safety, require, check, and runCatching
