Answer from AI

In Java, the Collection data structure is a basic interface from the java.util package that unites various groups of objects called elements. It serves as the foundation for more specialized interfaces such as List, Set, and Queue.

Main characteristics of Collection:

  • Allows storing and managing a set of objects.
  • Defines basic methods for adding, removing, checking for the presence of elements, and iteration.

Example of usage:

import java.util.ArrayList;
import java.util.Collection;

public class Example {
    public static void main(String[] args) {
        Collection<String> collection = new ArrayList<>();
        collection.add("Java");
        collection.add("Collection");

        for (String item : collection) {
            System.out.println(item);
        }
    }
}

Here, ArrayList implements the Collection interface, providing a dynamic array for storing elements.
