The abstract factory pattern is similar to the factory pattern and is a factory of factories. If you are familiar with the factory design pattern in Java, you will notice that we have a single factory class that returns the different subclasses based on the input provided and the factory clas...

Factory Method Design Pattern: Coding ExampleIn factory method design pattern mainly three classes/interfaces are involved, first, the factory class that creates an object from a given class hierarchy, second, an interface which is implemented by the concrete classes; objects of those classes will ...
It’s similar to the factory and can contain many factories in it; we can design many factories and relations with the design pattern in java. Simple factory class and many subclasses based on the input provided and switch statements to achieve as per project requirements. It helps in improvin...
Let’s understand this pattern with an example, suppose we want to provide an algorithm to build a house. The steps need to be performed to build a house are – building foundation, building pillars, building walls and windows. The important point is that the we can’t change the order ...

If we look into bridge design pattern with example, it will be easy to understand. Lets say we have an interface hierarchy in both interfaces and implementations like below image. Now we will use bridge design pattern to decouple the interfaces from implementation. UML diagram for the classes ...

the Objects are getting sorted in different ways. For our example, we will try to implement a simple Shopping Cart where we have two payment strategies - using Credit Card or using PayPal. First of all we will create the interface for our strategy pattern example, in our case to pay the...
