Does the Map interface extend the Collection interface in Java?

The Map interface in Java does not inherit from the Collection interface. This is because Map represents a data structure that stores key-value pairs, whereas Collection is an interface for collections of elements, where each element is a separate object.

Map and Collection are at the same level in the hierarchy of the Java Collections Framework, but Map is not a subtype of Collection. Instead, Map has its own methods for working with keys and values.

If you need to get a collection of values or keys from a Map, you can use the values() and keySet() methods, which return objects that implement the Collection interface.
