Consider the definition of LinkedBag’s add method that appears in Segment 3.12. Interchange the second and third statements in the method’s body, as follows:

firstNode = newNode;newNode.next = firstNode;

a. What is displayed by the following statements in a client of the modified LinkedBag?

BagInterface myBag = new LinkedBag();myBag.add("30");myBag.add("40");myBag.add("50");myBag.add("10");myBag.add("60");myBag.add("20");int numberOfEntries = myBag.getCurrentSize();String[] entries = myBag.toArray();for (int index = 0; index
b. What methods, if any, in LinkedBag could be affected by the change to the method add when they execute? Why?
