HELP: Sorted, Unsorted, & Indexed list

[Debonairj]

So I have two list (List1 & list2). Each has 4 add statements and one remove statements. Then 4 println statements (SOrted, list1, unsorted, list2).

UnsortedListInterface list1 = new RefUnsortedList();
SortedListInterface list2 = new RefSortedList();

Example:
list1.add("apple")
list1.add("pear")
list1.add("peach")
list1.add("orange")
list1.remove("peach")
and same thing for list2

But I'm not sure about the result...For unsorted, would it be thefoloowing and vice versa in a sense for list2 sorted.
apple
orange
pear

What is expected when I see the "Ref" appended to the newlist expected

Not sure what you are asking.
Do you have a problem with the code you posted? Do you get compiler errors?
Please copy and paste them here.

Norm, sorry for the confusion. This is two separate issues/questions I have posted....

On this particular thread, I'm trying to determine what is the expected result? Though it appears straight forward, the "REF" in front and attach to sorted or unsorted has thrown me through for a loop on the expected result..

Example: "Ref" - I'm not change what this does ot the expected result?
UnsortedListInterface list1 = new RefUnsortedlist();
list.add("apple");
list.add("pear");
list.add("peach");
list.add("orange");
list.remove("peach");

[Norm]

determine what is the expected result

Why not write a program and find out the actual result?

What you posted looks something like java code but it's hard to tell.
Where are the classes: UnsortedListInterface and RefUnsortedlist defined?
