Main data structures in Java.

## Main Data Structures

- Array

  - Array (fixed size array)

- List

  - ArrayList (dynamic size list)

  - LinkedList (linked nodes list)

- Map

  - HashMap (key-value pairs)

  - TreeMap (key-value pairs, sorted keys)

- Table

  - Hashtable (key-value pairs, no null key/value)

- Stack

  - Stack (LIFO)

- Queue

  - Queue (FIFO)

  - PriorityQueue (FIFO, sorted values)

- Set

  - HashSet (no repeating values, O(1) time)

  - TreeSet (no repeating values, sorted order, O(n) time)

  - LinkedHashSet (no repeating values, insertion order, O(1) time)

- Tree

  - BinaryTree (in-order, pre-order, post-order, level-order)

  - BinarySearchTree (left child < root < right child)

- Heap

  - MaxHeap (value of node > value of children)

  - MinHeap (value of node < value of children)

- Graph

  - AdjacencyListGraph (directed, undirected, weighted, unweighted)

  - AdjacencyMatrixGraph (2D array, directed, undirected, weighted, unweighted)
