    Builder pattern could be used when:
    • Creation algorithms of complexed objects are not dependent upon parts that compose the objects.
    • System allows the representation of many different objects.


    Vehicle Manufacturer

    Consider an example of vehicle manufacture that creates bicycle, a car, a scooter and a motorcycle. In such case, builder would be the Vehicle Builder. Interface is being specified to build any kind of vehicle in the above list by using similar ...

    Factory builder pattern is used by the builder design patter so that to make a decision which concrete class for initiation to build the desired object type.

    In this pattern, the participant classes are:
    • An abstract interface is specified by the builder class to create the product object parts.
    • ConcreteBuilder creates and puts the product parts together by doing the implementation of the builder interface. It also keeps the proper representation track that has been created

  3. Builder Pattern

    Complexity of the objects as well as classes increases along with the complexity of an application. Complex objects basically are manufactured of those parts that are produced by the various other objects which require special attention while building. A proper mechanism is needed by the application to build the complex objects, independent of those that build object. If you are also facing the same problems then try to use the Builder design pattern.

    Such patterns permit the client ...
