Question

Select the correct statement(s):

1)Exceptions are compiler errors

2) Exceptions can be thrown from a method. The caller of the method can catch and handle the exception.

3) The Throwable class is not the root of exception classes.

4) RuntimeException, Error, and their subclasses are known as unchecked exceptions.

Answer 1

Hi There,

Below is my answer:

Options 2 and 4 are correct answers.

Below are the explanations:

Option 2 is correct. We can use the keyword 'throws' which indicates that this method could throw the exception. The caller of these methods can handle this exception by using a "try-catch block".

Option 4 is correct. The class RuntimeException and its subclasses, and the class Error and its subclasses are unchecked exceptions classes. Because the compiler doesn’t forces them to be declared in the throws clause.

Why 1 and 3 are incorrect:

The event that disrupt to the normal flow during execution is called as an Exception. Exception can be of two types checked and unchecked exception. Checked exceptions occur during compile time and unchecked exceptions occur during run-time.

As exception is not just compiler errors (but also run-time), option 1 is incorrect.

The Throwable class is the superclass of all errors and exceptions. Hence, option 3 is incorrect.

Thanks!!Cheers!!Happy Chegging!!
