Java for Beginners 25 - Linked List data structure

[codenameFourtySeven]

You've got really nice way of explaining without going over the board ! Keep it up

Very cool your explanation of LinkedList, very interesting the way explains in your video lessons, I liked the approach showing the inner workings adding and removing list elements. On your next video I think it could have more examples in code, eg.

When we have problems with multiple threads accessing the LinkedList(concurrency) because the implementation is not synchronized.

Talk about the exceptions that can be for example when you remove an element from a queue and the same is empty.

Talk about the generalized and the problems that we will have when we removed objects from the collection.

private List<Object> objects = new LInkedList<Object>();

Use of generics, avoid the cast objects...
 private List<User> users = new LinkedList<user>();

Parameterization
private List<T> objects = new LinkedList<T>();

more examples and use of the pool in the Queue implementation.

Talk about interfaces in the colletions.

thanks for the lessons, hugs.

A stupid interview question that would prove you are very smart but in practice just proves you memorized a trick is "how to remove a node from a singly-linked list provided it isn't the last node in the list, given only a pointer to that one node (not even the head of the list)." The trick is to impersonate the guy who comes after you by altering your own value, then deleting them. This reminds me of creepy bad guys in spy and crime shows that kill someone and attempt to take over their lives. Not too relevant except I was very much reminded of it ~3:33 and maybe like scrum it is something prevalent but maybe not so great.

when to use use absract class and when to use interface?
please give me short and quick answer?
