I am having a problem with my code it seems to endlessly loop with user input of two temps never ending. As I am a newbie at this could someone take a look at what I've got so far and fix what's wrong here are my two classes This is my third week of class, I'd like to know how am I doing? [/TEX]

Take a second look at where your loop ends, and what you need to include in the loop to get the desired 'output'.

[TEX]I'm sorry but I don't get what you are talking about I've been at this for a week now I'm getting fustrated.[/TEX]

Yes I wrote it with help form text book I said I'm learning and this is an on-line class as well so not much input from instructor. Is it that bad?

No it doesn't appear bad just want to make sure you understand what you coded here. Do you know much about do/while loops? Do you see where your loop is incorporated into the main method here?

If your still having trouble here, i'll compile the code when i get off work today and take a closer look at it. As for the problem you are experiencing above, take a closer look at the main method(the first method in the code) and look at the loops you have incorporated. Try to find what might be causing user input to loop infinitely.

Thanks any pointers you can give me would be greatly appreciated

I'm getting a few different compilation errors, Do you have any IDE or some sort of compiler for java? If not i would recommend NetBeans. It's free, and pretty easy to use once you get the hang of it.
