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...

The facade pattern doesn’t force us to unwanted tradeoffs, because it only adds additional layers of abstraction. Sometimes the pattern can be overused in simple scenarios, which will lead to redundant implementations. 5. Conclusion In this article, we’ve explained the facade pattern and demonstr...
It is on the inputs from clients we create or has a superclass with multiple sub-classes. This is the most widely used java design pattern because this pattern takes responsibility for instantiating a class from the client program to the functional class. This pattern is flexible in applying ...
