Core Java Programming Course- Checked and Unchecked Exceptions

The video tutorial explains the difference between checked and unchecked exceptions in Java. Checked exceptions are verified at compile time and must be handled using try-catch or throws. Unchecked exceptions occur at runtime, often due to incorrect input, and are not caught by the compiler. The tutorial emphasizes handling checked exceptions as a standard practice, while unchecked exceptions should be allowed to terminate the program. The video also outlines the methods to handle exceptions and the rationale behind these practices.

What is a characteristic of checked exceptions?

• They occur due to incorrect input data.

• They are ignored by the compiler.

• They are verified at runtime.

• They must be handled in the code.

Which of the following is an example of an unchecked exception?

• FileNotFoundException

• SQLException

• IOException

• ArithmeticException

Unchecked exceptions are primarily caused by:

• Compiler errors

• Incorrect input data

• Syntax errors

• Network failures

What is the recommended practice for handling exceptions in Java?

• Handle only unchecked exceptions

• Handle only checked exceptions

• Ignore all exceptions

• Handle both checked and unchecked exceptions

According to Java developers, what should be done with unchecked exceptions?

• They should be ignored.

• They should be handled using try-catch.

• They should be thrown and let the program terminate.

• They should be converted to checked exceptions.
