In continuation of my posts on Creational design patterns, I will be discussing about the Singleton pattern in this post. You can read about the other patterns from the following links.

1. Prototype Pattern
2. Factory Method Pattern

You can read about Structural Patterns from here.

Singleton pattern deals with ensuring that there is only one instance of a class and providing a single global access point to that object. It also ensures that the object is not created until its actually needed.

In continuation of my posts on Creational design patterns, I will be discussing about the Factory Method pattern in this post. You can read about the other patterns from the following links.

1. Prototype Pattern

You can read about Structural Patterns from here.

The Factory Method pattern deals with creation of objects in which the subclasses decide which class's object has to be created. Various subclasses may implement the same interface, but the Factory Method creates the appropriate object based on some supplied information.

Continuing with the series on Design patterns, I will take up Creational Patterns from today. I have written about Structural Patterns in my previous posts. You can get all the links for them here.

Creational Patterns

Creational patterns deals with separation of a system in terms of how their objects are created, what they are made of and how they must be represented. There are 5 types of creational patterns as observed by the GOF. I will write about the Prototype pattern today.

The Prototype

In the previous few posts I have been writing about design patterns and for now I have completed the structural patterns as described by the GOF. Below are the links to all the structural patterns.

This is the continuing post in a series of post on Design patterns. Presently we are going through the structural patterns. I will be writing about the Façade pattern today. This would be the last structural pattern.

This is the continuing post in a series of post on Design patterns. Presently we are going through the structural patterns. I will be writing about the composite pattern today.

You can read about the other patterns from the following links

1. Decorator Pattern
2. Proxy Pattern
3. Bridge Pattern

Composite pattern deals with providing a structure such that a single object ( component ) or a group of objects ( composite ) can be treated in the same way. This saves the caller of this composite from knowing the objects individually. Lets see an example.
