$2.$ Consider the definition of LinkedBag$$s add method that appears in Segment $3\mathrm{.}12.$ Interchange the second and third statements in the method$$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$()$;

Object$[]$ entries $=$ myBag.toArray$()$;

for $($int index $=0$; index $<$ numberOfEntries; index$++)$

System.out.print$($entries$[$index$]+"")$;
