Using Java programming language create a linked list named Cars with four elements: "SUV cars", "Pickup cars", "Sport cars", and "Sedan cars". Apply the following activities on the code you've created and provide screen shot of each result: 1- Add a new element "Classic car" at the beginning of the linked list using iterator. 2- Add a new element "Economic cars" after the element "Sedan Cars" using iterator. 3- Print the LinkedList backward from the last element to the first element using hasPrevious()
