The Java Collections class is part of the java.util package and provides static utility methods to operate on or return collections. It is not a framework but a helper class designed to simplify common collection operations like sorting, searching, and manipulation. Key methods include:
- sort(List): Sorts a list in natural or custom order.
- binarySearch(List, key): Searches for an element in a sorted list.
- reverse(List): Reverses the order of elements in a list.
- shuffle(List): Randomly permutes elements in a list.
- unmodifiableCollection(Collection): Returns an unmodifiable version of the collection.
This class enhances the usability of Java’s collection framework by offering efficient and reusable solutions for routine tasks.
