Definitions:

Exception Object

An object that represents an error or irregularity that occurs during the execution of a program. In many languages, exception objects can be caught and handled by exception handling mechanisms.

Instance Variable

A variable defined in a class for which each instantiated object of the class has its own copy, representing the object's state.

Unchecked Exceptions

In programming, especially Java, these are the exceptions that are not checked at compile-time but at runtime.

Catch Or Declare Rule

The catch or declare rule in programming mandates that a method must either catch an exception with a try-catch block or declare it in its throws clause.
