System.out.println(myLinkedList); 

// Print the value at list index 2:
System.out.println(myLinkedList.get(2));

// Empty the list

// Print the newly emptied list: []

// Adds a node with data="Sixth" to back of the (empty) list

//The above code produces the following output:
[Third, First, Fifth, Second, Fourth]
Fifth

[Sixth]
