Are this:

tail.next = newNode;
tail = newNode;

and this

tail.next = tail = newNode;

the same thing?

[Reeling]

why not put that in to an IDE and test it?

[therealyacek]

I will test it once I finish all my methods in my class since my class implements an interface and I can't compile it right now until I have all the classes done...
was just wondering before hand so I could clean up my code some.

[Reeling]

create a new file and compile it.

[pbrockway2]

No, they're not the same thing.

Proof: (without compiler) The first is a couple of straight forward assignments. It is clear what it does.

The second isn't clear. It even makes the author stop and wonder.

Therefore they aren't the same.

---

Of course, they may (or may not) do exactly the same thing. They may (or may not) be functionally equivalent and generate the same byte code. To figure that one out, Reeling has the right idea.

Bad approach, and expecially so for a beginner. Make the habit of compiling every time you add a few lines. That way you don't end up with an overwhelming amount of compiler errors, and for the one or two you might experience, you know exactly where to look: the code you've just written.

If your problem is that an interface is yet to be implemented, you have some options to allow you to compile:
-- add an empty implementation, or one that throws UnsupportedOperationException
-- temporarily declare the class abstract
-- temporarily comment out the implements clause
