Can you explain what is meant by collections in programming?

In programming, collections are data structures that allow storing and managing groups of objects.

In Java, collections are represented in the java.util package and include various types:

• List — an ordered list of elements, allowing duplicates (e.g., ArrayList, LinkedList).
• Set — a collection of unique elements, without a specific order (e.g., HashSet, TreeSet).
• Map — a key-value mapping, where keys are unique (e.g., HashMap, TreeMap).

Collections facilitate working with data by providing methods for adding, removing, searching, and iterating over elements.

Example of using List:

List<String> fruits = new ArrayList<>();
fruits.add("Apple");
fruits.add("Banana");
for (String fruit : fruits) {
    System.out.println(fruit);
}

Collections are a fundamental part of Java and help manage data sets efficiently.
