What is LinkedList in Java? 👉 LinkedList is a linear data structure implementation in Java that stores elements as nodes connected using pointers (links). Instead of an array, it uses: Node structure Each node has: data reference to next node reference to previous node 🔹 Key features ✔ 1. Dynamic size Grows and shrinks automatically No fixed capacity like arrays ✔ 2. Fast insert/delete No shifting required Just change links Example: Insert B between A and C → just update pointers ✔ 3. Slow random access list.get(5); 👉 Must traverse node-by-node → O(n) time 🔹 Constructors in LinkedList ✔ Default: LinkedList < String > list = new LinkedList <>(); Enter fullscreen mode Exit fullscreen mode ✔ From collection: LinkedList < String > list = new LinkedList <>( otherList ); Enter fullscreen mode Exit fullscreen mode Important interfaces it implements LinkedList implements: List Deque Queue So it can act like: List Stack Queue 🔹 1.…
