Java Collections Framework: A Beginner’s Guide

The Java Collections Framework is a powerful set of classes and interfaces that help you store and manipulate groups of objects. Whether you’re working with lists, sets, or maps, the Collections Framework has you covered.

In this blog, we’ll explore:

• Common interfaces like List, Set, and Map.
• Popular implementations like ArrayList, HashSet, and HashMap.
• How to iterate through collections using loops and iterators.

Here’s an example of using an ArrayList:

import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        ArrayList<String> fruits = new ArrayList<>();
        fruits.add("Apple");
        fruits.add("Banana");
        fruits.add("Cherry");

        for (String fruit : fruits) {
            System.out.println(fruit);
        }
    }
}

The Collections Framework is a must-know for any Java developer. Start using it to make your code more efficient and organized!
