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 ...
Besides a much simpler interface, there’s one more benefit of using this design pattern. It decouples a client implementation from the complex subsystem. Thanks to this, we can make changes to the existing subsystem and don’t affect a client. Let’s see the facade in action. 3. Examp...
Singleton design pattern is used in core Java classes also (for example,java.lang.Runtime,java.awt.Desktop). Java Singleton Pattern Implementation To implement a singleton pattern, we have different approaches, but all of them have the following common concepts. ...

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 ...
