Does Map interface extend or implement some other interface or class?

Question

We know that Map interface does not implement Collection interface. Then what does Map implement or extend? Does it extend Object class directly?

Generally best to read the [Java Tutorials](https://docs.oracle.com/javase/tutorial/java/concepts/index.html) by Oracle before posting on basic topics. — Basil Bourque, Aug 02 '20 at 06:11

Map does not extend any interfaces; it is defined as its own interface.

In Java, interfaces don't extend classes, only other interfaces. Technically, all objects in Java extend Object, so any object implementing an interface is an Object.
