Implementation

The use case here is to build a pizza based on customer specification. PizzaBuilder is an abstract class that dictates the steps to build pizza and also orchestrates the pizza making steps. VeggiePizzaBuilder, PizzaPepperoniBizzaBuilder and ChickenPizzaBuildera extends PizzaBuilderClass. The only method they override is addToppings() method. VeggiePizzaBuilder adds topics like tomato, green pepper and onions. PeopporoniPizzaBuilder adds pepperoni slices. ChickenPizzaBuilder adds grilled checkin toppings. Rest of the methods remain same for all three types of pizzas. Director class determines which PizzaBuilder class it should invoke based on PizzaType specification from customer. Client class represents customer who is placing the order. This relationship is explained in picture below. Note that ‘+’ prefix in front of method denote public methods whereas ‘#’ prefix denotes protected methods
