Definitions:

Private Instance Variable

A variable defined in a class that cannot be accessed directly from outside the class, providing a level of data encapsulation.

Wrapper Class

A class that encapsulates primitive data types into objects, allowing primitives to be used as objects.

Primitive Type

Basic data types provided by a programming language as building blocks, such as int, char, and float in Java.

Unboxing

The automatic conversion of an object of a wrapper class (like Integer or Boolean) back into its corresponding primitive type.
