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...

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 ...
Java+ Design Pattern Regression testing is very important to ensure that new code doesn't break the existing functionality.
