Factory Design Pattern:
It falls under
Creational Design Pattern
.
Factory pattern says that object creation will be handled by another class using the input type.
Advantages:
It allows loose-coupling.
When to use Factory Design Pattern?
Factory design pattern is used when we have a superclass with multiple sub-classes and based on the input, we need to return one of the sub-class.
Example: If a Restaurant serves Veg food, Non-Veg food, and Italian food.
Treat VegFood, NonVegFood, and ItalianFood as three classes whose superclass is Food.
If a customer asks "Veg" then Factory method would return the "VegFood" class.
