We create a custom Node class which can take values of generic type T, so that we can create linked lists of different types using the same implementation class.We also create a LinkedList class which will hold the actual linked list of nodes. In the above example, we have created a LinkedList named languages. How can i extract files in the directory where they're located with the find command? We provide programming data of 20 most popular languages, hope to help you! The data can be of int, String, or float and prev and next are of the Node type. Since the LinkedList class also implements the Queue and the Deque interface, it can implement methods of these interfaces as well. * * synchronized externally.
