Mastering Java: Advanced Topics in Java Collections Framework
Welcome back to our Java series! In this article, we’ll delve deeper into advanced topics of the Java Collections Framework (JCF), exploring more complex data structures, algorithms, and techniques for efficient data management.
1. Working with Collection Interfaces
Java provides several core interfaces that define different types of collections:
- List: Ordered collection (e.g., ArrayList, LinkedList).
- Set: Unordered collection of unique elements (e.g., HashSet, TreeSet).
- Queue: Ordered collection for holding elements prior to processing (e.g., LinkedList, PriorityQueue).
- Map: Key-value pairs where each key is unique (e.g., HashMap, TreeMap).
Each interface has specific methods for manipulating and accessing elements.
2. Understanding Iterators and Iterable Interface
Iterators provide a way to traverse collections. The Iterable
interface enables objects to be used with the enhanced for loop.
Example:
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
public class IteratorExample {
public static void…
