What are the three different patterns?

Number Patterns. A list of numbers that follow a certain sequence is known as patterns or number patterns. The different types of number patterns are algebraic or arithmetic pattern, geometric pattern, Fibonacci pattern and so on. Now, let us take a look at the three different patterns here.

As per the design pattern reference book Design Patterns – Elements of Reusable Object-Oriented Software , there are 23 design patterns which can be classified in three categories: Creational, Structural and Behavioral patterns .

The Creational pattern focuses on object creation; the Structural pattern relies on the relationship between objects, and Behavioural builds its communication between objects .
