Explanation

To declare a class that implements an interface, you include an implements clause in the classdeclaration. By convention, the implements clause follows the extends clause, if there is one. Here are the some point that must be considered while implementing an interface (or interfaces) into a A class implementing an interface must either implement all the methods of that interface otherwise known asthe abstract class. A class in java may extend at most one superclass because java does not allow multiple inheritance, by it mayimplement more than one interface. Multiple inheritance in java is achieved through the interfaces. When aclass implements more than one interface then implement statement requires a comma- separated list ofinterfaces to be implement by that class.
