Core Java Programming Course- Error vs. Exception

The video tutorial explains the difference between errors and exceptions. Errors are issues that applications should not try to recover from, such as out of memory or stack overflow errors, typically thrown by the JVM. Exceptions, on the other hand, are recoverable situations that applications should handle, like file not found or SQL exceptions. Both errors and exceptions are subclasses of the Throwable class. Exceptions are further classified into checked and unchecked types, which will be discussed in the next session.

What is the main difference between an error and an exception?

• Errors are problems that should not be caught, while exceptions can be caught and handled.

• Errors can be caught and handled, while exceptions cannot.

• Errors are specific to syntax issues, while exceptions are not.

• Errors are less severe than exceptions.

Which of the following is an example of an error that cannot be recovered at runtime?

• Out of memory error

• Null pointer exception

• SQL exception

• File not found exception

What should a reasonable application do when it encounters an exception?

• Ignore it and continue execution

• Convert it into an error

• Terminate the program immediately

• Catch it and provide steps to recover

What is the superclass for both errors and exceptions?

• Error

• Throwable

• RuntimeException

• Exception

Which type of exception will be discussed in the next session?

• Logical exceptions

• Syntax exceptions

• Checked and unchecked exceptions

• Runtime exceptions
