Question

Which statements are correct about 'unchecked exceptions'?

a) Exceptions inherit from 'Exception'
b) Exceptions inherit from 'Error'
c) Exceptions inherit from 'RuntimeException' class
d) All of the above

Answer 1

Unchecked exceptions in Java inherit from the 'RuntimeException' class, which means that option c) is the correct statement.

Step-by-step explanation:

In regards to the correct statements about 'unchecked exceptions' in Java:

• Exceptions inherit from 'Exception': This is partially true. All exceptions in Java are subclasses of java.lang.Exception, but this is not specific enough for unchecked exceptions.
• Exceptions inherit from 'Error': This is incorrect. Errors are a separate category under java.lang.Throwable. They represent serious problems that a reasonable application should not try to catch.
• Exceptions inherit from 'RuntimeException' class: This is correct. Unchecked exceptions are those that extend java.lang.RuntimeException and do not need to be declared in a throws clause or surrounded in a try-catch block.

Therefore, the correct statement regarding 'unchecked exceptions' is c) Exceptions inherit from 'RuntimeException' class.
