Question

True or False: A class that implements an interface may only implement a few of that interface's method declarations

Answer 1

Answer:

False

Explanation:

Whenever a class implements an interface, it has to define all the functions which are declared in the interface because in the interfaces, methods are only declared and not defined, so, if a method is left undefined, it leads to compilation error, that is why, all methods of an interface has to be defined by the class which is implemented that method.
