Answer / nashiinformaticssolutions
• An Unchecked exception inherits from RuntimeException (which extends from exception). The JVM treats RuntimeException differently as there is no requirement for the application code to deal with them explicitly.
• A checked exception inherits from the exception class. The client code has to handle the checked exceptions either in a try-catch clause or has to be thrown for the super-class to catch the same. A checked exception thrown by a lower class (sub-class) enforces a contract on the invoking class (super-class) to catch or throw it.
• Errors (members of the error family) usually appear for more serious problems, such as OutOfMemoryError (OOM), that may not be so easy to handle.
