Want cleaner, safer Java code? Master error handling.

1. Understand Exceptions:
Checked exceptions must be handled or declared — unchecked don’t require it but can still break your app.

2. Use try-catch wisely:
Catch only what you can handle. Avoid catch(Exception e) unless absolutely necessary.

3. finally matters:
Use finally for cleanup — closing files, releasing resources, or ending database connections.

4. Throw custom exceptions:
Make errors more descriptive by creating your own exception classes.

5. Don’t swallow errors:
If you log it, act on it — otherwise, debugging becomes a nightmare.

Handle errors with intention, and your Java code becomes both robust and reliable.
