Public class ClassName extends SuperclassName implements FirstInterface ,Īll objects of a class that implement multiple interfaces have the is-a relationship with each implemented interface type.Ĭlass Invoice implements the one method in interface Payable. To implement more than one interface, use a comma-separated list of interface names after keyword implements in the class declaration, as in: In fact, a class can implement as many interfaces as it needs, in addition to extending another class. Java does not allow subclasses to inherit from more than one superclass, but it does allow a class to inherit from a superclass and implement more than one interface.
