What is the difference between Collection and Collection's in java
Hi, team,
I’m a B.Tech 3rd-year student, and I’ve recently started learning Core Java.
I’ve almost completed the basics. One of my seniors asked me, "What is the difference between Collection and Collections?
To be honest, I know what a Collection is, but I don't really understand the difference between Collection and Collections.
Can someone please tell me if this is an important interview question? Also, how should I answer it if someone asks me again?
I would really appreciate it if someone could provide the correct answer

First of all, this is a very important question. Whether you are a fresher or experienced, you must know the Collection Framework, as it is one of the most crucial topics in Java. Everyone should have a solid understanding of it.
Now, apart from your main question, let me clarify the difference between Collection and Collections:
- Collection is an interface, while Collections is a utility class.
- Collection is the root interface in the Collection Framework (after the Iterable interface) that provides the basic structure for working with groups of objects. On the other hand, Collections is a class that provides utility methods, such as sorting, searching, and synchronization, for working with collections.
