Putting an object as an member variable of another object(say domain object) for providing more functionality or for business purpose is called wrapping an object. Example: wrapper classes that wraps primitive types such that primitive type values can be treated as objects

It provides wrapper classes to manipulate primitive data elements as objects, such data elements are wrapping an object. Primitive data types wil be boolean, int ,float, double, char, Wrapper class will be Boolean, Integer, Float, Double, Character.
As we know that Java is not fully (100%) object oriented programming
language, because we use some predefined instance like int, float, et al. so we
use wrapping class to change this thing into object.
