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 ...
In this article, we investigate both questions, using the strategy pattern as an example. Our main contribution is that we show how to reason about different implementations, using both the description of a design pattern and design principles as guidance....
Interpreter (recognizeable by behavioral methods returning a structurally different instance/type of the given instance/type; note that parsing/formatting is not part of the pattern, determining the pattern and how to apply it is) java.util.Pattern java.text.Normalizer All subclasses of java.text....
