Accessor Methods

Definition

Accessor methods, also known as getter methods, are a type of method in object-oriented programming that allows the retrieval of the value of an object's private data member. They provide read-only access to the internal state of an object.

Analogy

Think of accessor methods like a vending machine. You can't directly access the snacks inside the machine, but you can use the buttons on the outside to retrieve information about what snacks are available and their prices.
