The LinkedList class defines the following methods for manipulating lists. These are as follows:
- void addFirst(E obj): This method inserts an element at the beginning of the list.
- void addLast(E obj): This method inserts an element at the end of a list
- E getFirst(): This method is used to retrieve the first element from the list.
