This means that every single class implementing Collection in any form is part of the Java Collections Framework.\ The Collections Framework is Java's native implementation of data structure classes (with implementation specific properties) which represent a group of objects which are somehow related to each other and thus can be called a collection.\ **Collections** is merely an utility method class for doing certain operations, for example adding thread safety to your ArrayList instance by doing this:\ List list = Collections.synchronizedList(new Arraylist());The main difference in my opinion is that Collection is base interface which you may use in your code as a type for object (although I wouldn't directly recommend that) while Collections just provides useful operations for handling the collections. --- Original Source: https://www.mindstick.com/forum/23381/differentiate-between-collection-and-collections Copyright © MindStick Software Pvt.
