Get Method (Accessor)

Definition

A get method, also known as an accessor, is a method used to retrieve the value of an object's private instance variable. It provides read-only access to the data stored in the object.

Analogy

Think of a get method as a vending machine that dispenses information instead of snacks. Just like how you insert money into a vending machine and it gives you the desired item, a get method allows you to "insert" an object and receive its private data in return.
