Interface (Provided)
An interface (provided) specifies a set of abstract operations. The operations are the external view of the classifier and do not reveal to the client the way that the operations are implemented by the classifier. An interface is conceptually an abstract classifier without attributes. A classifier is said to "implement an interface" if it provides the implementation of all or some of the operations declared by the interface. This relationship is shown by a realization drawn from the classifier with the arrow pointing to the interface. An interface cannot have instances.
Explanation
An interface is a set of operations that define the services offered by classifiers that realize the interface. It can be thought of as a specification or a contract for behavior. The interface itself does not carry out the work, but rather the classifiers that are said to realize the interface actually perform the operations.
