Data Structures in Java

Data structures in Java are essential components for managing and organizing data efficiently. They provide structured ways to store, access, and manipulate information, which is vital for building scalable and optimized applications. Since Java is an object-oriented programming language, it offers both built-in data structures and collections through the Java Collections Framework (JCF).
At the most basic level, Java supports primitive data structures such as integers, characters, and booleans. More advanced non-primitive data structures include arrays, classes, and interfaces. Arrays are one of the simplest forms, storing elements of the same type in contiguous memory locations, making them useful for fast indexing. However, arrays are static in size, which limits flexibility.
To overcome such limitations, Java provides dynamic data structures like Linked Lists, where elements are connected through pointers. Linked lists make insertion and deletion efficient compared to arrays. Similarly, Stacks and Queues are widely used. A stack follows the Last In, First Out (LIFO) principle, making it suitable for function calls and undo mechanisms, while a queue uses the First In, First Out (FIFO) method, ideal for scheduling tasks.
