Question 1: Modify the class LinkedList by adding to it the following methods. The appropriate error message should be generated if an invalid condition occurs.

Part b: int length(): create this function to determine the number of items in the list (accessor function).
Part c: void clear(): create this function to remove all of the items from the list. After this operation is completed, the length of the list is zero.
Part d: void insertEnd(int item): create this function to insert item at the end of the list.

Part f: int get(int location): create a function that returns the element at the positionlocation.
Question 2 :-. Using the class LinkedList, write a program to store 50 random numbers.
Suppose that each of these random numbers is an integer in the interval [10, 99]. There must be no duplicate numbers in the list.
You need to implement the link list using java programming concepts.
