A small Java project with custom implementations of core data structures.

Implemented Structures

Linked List

Generic singly linked list implementation with:

• add element to the end
• insert element at a specific index
• get element by index
• remove element by index
• size tracking
• custom string representation

Doubly Linked List

Generic doubly linked list implementation with:

• head and tail references
• add element to the end
• insert element at a specific index
• get element by index
• remove element by index
• forward and reverse string representation
• optimized node search from both directions

Queue

Generic queue implementation built on top of the doubly linked list with:

• enqueue
