    Google the terms and tell us what you think...

    I did not get proper information. Different posts provide contradictory information about same concept.

    An IoC instances the object that is kept in an IoC container so that you don't have to use the 'new' keyword to instance the object gluing your code to the object's implementation, which promotes loose coupling.




    DIP is about the abstraction  between high level and low level object.

    These are patterns to achieve loose coupling in java programming

    DI(Dependency Injection):
    Dependency injection is a pattern used to create instances of objects that other objects rely upon without knowing at compile time which class will be used to provide that functionality or simply the way of injecting properties to an object is called dependency injection.

    We have three types of Dependency injection

    1. Constructor Injection
    2. Setter/Getter Injection
    3. Interface Injection

    Most Web Dev framework support only Constructor Injection and Setter/Getter Injection.

    IOC(Inversion Of Control):
    Giving control to the container to create and inject instances of objects that your application depend upon, means instead of you are creating an object using the new operator, let the container do that for you. Inversion of control relies on dependency injection because a mechanism is needed in order to activate the components providing the specific functionality

    The two concepts work together in this way to allow for much more flexible, reusable, and encapsulated code to be written. As such, they are important concepts in designing object-oriented solutions.

    IoC (Inversion of Control) is a generic term meaning rather than having the application call the methods in a framework; the framework calls implementations provided by the application.

    DI (Dependency Injection) is a form of IoC, where implementations get passed into an object through constructors/setters/service-lookups, which the object will depend on to behave correctly.
