What is exception handling and how does it work?
A core programming concept question regarding error management and program stability in software development.
Why Interviewers Ask This
Robust code must handle errors gracefully. Interviewers want to ensure you know how to prevent crashes and provide meaningful feedback during runtime failures.
How to Answer This Question
Define exception handling as managing runtime errors. Explain try-catch blocks, finally block usage, and throwing exceptions. Differentiate between checked and unchecked exceptions if applicable to the language discussed.
Key Points to Cover
- Try-catch mechanism
- Error prevention
- Resource cleanup
- Program stability
Sample Answer
Exception handling allows programs to catch and manage runtime errors without crashing. It uses try blocks to wrap risky code and catch blocks to handle specific errors. The finally block executes cleanup code regardless of whether an exception occurred. This ensures resource release and stable execution.
Common Mistakes to Avoid
- Swallowing exceptions silently
- Using broad catch types
- Forgetting finally blocks
