Suppose there’s a

LinkedList

of

Customer

elements as described in Exercise 7. This time, suppose another variable called

lineCrasher

refers to a new

Customer

object. Write a code fragment that inserts the

lineCrasher

object into the linked list just before the

customer

object. [Hint: If you are careful about the sequence, and you use some chaining, you can do this with no additional variable declarations and just four statements.]
