Interfaces are a way of imposing a type of functionality on all other java classes that are created using it. It is kind of a template that all child classes using this template must follow. All methods that are declared in an interface must be implemented by the child classes and hence the functionality offered by these classes can be controlled using them.

Interfaces are a powerful tool that java provides to achieve multiple inheritance.
