After getting introduced to Design Patterns we have so far examined the following patterns:

• Adapter Pattern
• Facade pattern
• Composite Pattern
• Bridge Pattern
• Singleton Pattern
• Observer Pattern
• Proxy Pattern
• Chain of Responsibility Pattern
• Flyweight Pattern

Now, we will now get to know the Builder Design Pattern.

The intent of the Builder Pattern is to separate the construction of a complex object from its representation, so that the same construction process can create different representations. This type of separation reduces the object size. The design turns out to be more modular with each implementation contained in a different builder object. Adding a new implementation (i.e., adding a new builder) becomes easier.

Via a real life example, you will learn how and when the Builder design pattern should be used and how to structure your code in order to implement it. You will see how it can lead to elegant solutions to code problems.
