    Design patterns are mainly of three types
    Creational
    Structural
    Behavioral

    Creational patterns are ones that create objects for you,
    rather than having you instantiate objects directly. This
    gives your program more flexibility in deciding which
    objects need to be created for a given case.

    Structural patterns help you compose groups of objects into
    larger structures, such as complex user interfaces or
    accounting data.

    Behavioral patterns help you define the communication
    between objects in your system and how the flow is
    controlled in a complex program
