What are checked and unchecked exceptions in Java?

Can you explain the difference between checked and unchecked exceptions in Java?

Sure! In Java, checked exceptions are exceptions that must be either caught or declared in the method signature. Unchecked exceptions, on the other hand, do not require this and are usually a result of programming errors.

Can you give me examples of each type?

Absolutely! An example of a checked exception is IOException, which must be handled. An example of an unchecked exception is NullPointerException, which occurs when you try to use an object reference that has not been initialized.

Why is it important to handle checked exceptions?

Handling checked exceptions is important because it forces developers to consider potential error conditions and handle them appropriately, leading to more robust and error-resistant code.

What happens if I don't handle a checked exception?

If you don't handle a checked exception, your code will not compile unless you declare the exception in the method signature, which ensures that the exception is addressed.
