An interface is best used for providing services that bring together objects of otherwise unrelated classes. Interfaces are used to achieve multiple inheritance in Java since a class can implement multiple interfaces. They are used to define a set of methods that a class must implement, thereby providing a way to achieve polymorphism in Java. Abstract classes, on the other hand, provide a way to define a base class that can be extended by concrete classes. Concrete classes are used to create objects that can be instantiated, whereas abstract classes cannot be instantiated.
