For declaring Functional Interfaces annotation is optional to use. Due to which it is also known as the Single Abstract Method (SAM) interface. It is known as a functional interface because it wraps a function as an interface or in other words a function is represented by a single abstract method of the interface.įunctional interfaces can have any number of default, static, and overridden methods. What are functional or SAM interfaces?įunctional Interfaces are an interface with only one abstract method. ![]() This improves the garbage collection, auto-tuning, and de-allocation of metadata. It is not a contiguous Heap Memory and hence can be grown dynamically which helps to overcome the size constraints.

The film's core technical crew includes cinematographer Saran Velayudhan, editor Nishad Yusuf and music composer Paali Francis.
