Introduction Design patterns are recurring solutions to software design problems you find again and again in real-world application development. Patterns are about design and interaction of objects, as well as providing a communication platform concerning elegant, reusable solutions to commonly encountered programming challenges. The Gang of Four GoF patterns are generally considered the foundation for all other patterns. A total of 23 GoF patterns exist. They are categorized in three groups: Creational, Structural, and Behavioral.

It seems this conflicts with the statement that "Factory Methods return abstract classes or interface" when it this says "Factory Methods are abstract and return class types".
