Answer 2

In a Linked List you have depending ob implementation 2 classes:
-LinkedList
-LinkedListNode

the LinkedList is used to make changes and access the list.
the LinedListNodes are the actual structure.

Inside the LinkedList we have a LinkedList-start which in the beginning holds null, because the list is empty.

when we add an element (to the end) we test if the start is null, if it is we set it to a new LinkedListNode containing the element to be added, if it isn't null, we call it's function to add.
The LinkedListNode has 2 attributes, content and next, they are self explainatory.
Now when the method add of an LinkedListNode is called it tests if next is null, if it's not we call the function add of next if it is we set it to a new LinedListNode containing zhe content.

There are many diffrent implementations, like adding 2 more classes for faster and easier recursion calls...

hope this helps!
happy coding! 😄

Anton Böhler Thanks you for your clear explanation , and yea i saw too much of code of linkedlist and differently implementations of those make me confused.that would be awesome if got a video plus step by step ,well btw thanks a lot
