LinkedList in Java

Question

Can you explain me LinkedList(java) in simple way as possible? Where it used? Why it used? Benifits of it.

Answer 1

You can think of LinkedList as small chunks of memory. In contradiction to Array, array is contiguous memory allocation but LinkedList can be discrete allocation.
LinkedList is a set of nodes that are connected by a link.
Node of a LinkedList contains two things. First- It contains the data or value.
Second- It contains the address/pointer of Next node.
First node of a LinkedList is called head node and last node is tail. Address of head is contained in another variable. A LinkedList is accessed by it's head node.
