How do you use Collections utility class with a simple code example?

The Collections utility class in Java provides various methods for performing operations on collections, such as sorting, searching, and modifying. It is part of the java.util package and offers a range of static methods to manipulate collections.

Here’s a simple example demonstrating how to use the Collections.sort() method to sort a list of strings:

import java.util.ArrayList; import java.util.Collections; import java.util.List; public class CollectionsExample { public static void main(String[] args) { List fruits = new ArrayList<>(); fruits.add("Banana"); fruits.add("Apple"); fruits.add("Orange"); // Sorting the list of fruits Collections.sort(fruits); // Displaying the sorted list System.out.println("Sorted fruits: " + fruits); } }
