What are some examples of Java collections?

Java collections are frameworks that provide a way to store and manipulate groups of objects. Examples include List, Set, and Map.

Can you explain the difference between List and Set?

Sure! A List allows duplicate elements and maintains the order of insertion, while a Set does not allow duplicates and does not guarantee order.

What about the Map interface?

A Map is a collection that maps keys to values. It does not allow duplicate keys, but values can be duplicated.

Can you give me a code example of using a List?

Certainly! Here's a simple example:

import java.util.ArrayList;

public class Example {
    public static void main(String[] args) {
        List<String> fruits = new ArrayList<>();
        fruits.add("Apple");
        fruits.add("Banana");
        System.out.println(fruits);
    }
}
