When should I use checked exceptions in Java?

When should I use checked exceptions in Java?

Checked exceptions are used when the caller is expected to handle the exception, ensuring robust error handling.

Can you give me an example of a checked exception?

Sure! An example of a checked exception is IOException, which must be handled or declared in the method signature.

What about unchecked exceptions? When should I use those?

Unchecked exceptions, like NullPointerException, indicate programming errors and don't require explicit handling.

Is it a good practice to use checked exceptions for all errors?

Not necessarily. Use checked exceptions for recoverable conditions and unchecked for programming errors to keep code clean.
