To define an interface. Other times the name may omit the word interface but still indicates a contract. If we combine multiple Web APIs then we can create a composite API which is a collection of data or service Application Programming Interface.

Or the commonly used application program interfaces APIs and command-line interfaces CLIs. It is used to achieve multiple inheritance. What is an interface in Java.
