Definitions:

Implements

A keyword in Java used by classes to specify that they will provide implementations for the methods defined in an interface.

Interface

In programming, an interface is a reference type that defines a set of abstract methods that a class must implement.

Concrete Class

A class that has an implementation for all of its methods, as opposed to abstract classes which can contain unimplemented methods.

Abstract Class

A class that cannot be instantiated and is designed to be subclassed, often containing one or more abstract methods which must be implemented by subclasses.
