Java linked list visualizer

A linked list is a chain of objects, each holding a reference to the next. Step through it and the visualizer draws every node as an object, with arrows for the references between them.

What to watch

  • Each new Node becomes its own object, and next starts out as null.
  • head.next.next follows two references to reach the third node.
  • In the loop, current moves along the chain one reference at a time until it reaches null.

Try changing it

  • Insert a new node between the first and second nodes.
  • Write a method that returns the length of the list.
