Design Patten is the pattern of problem solving solution where the problem can be found very often for the complex systems.
There are three group of design pattern such as Creation Patterns, Structural Patterns and Behavioral Patterns.
Creation Patterns
Factory Pattern: In order to create the objects that use the same interface with different implementation.
Abstract Factory Pattern: When we need to decide which class to instantiate from a set of different implementation. This patten can decide from a group of different implementation.
Singleton Pattern: Very useful patten when we want to have only one single instance of the class for the whole process.
Builder Pattern: To build the complex objects by combination of simple objects step by step.
Prototype Pattern: Use the existing object instead of creating new one. This is not very popular since it would affect the performance.
