Re: Java Variable Question

Thanks Thorbjoern!
I figured it was something like that, but I just wasn't sure so I thought I
would ask.

Yes, the color coding really does help. It's very helpful in a constructor
when you try to initialize a variable but you forgot the this. prefix. You
have to love the modern IDE.

That is rather strange. You would THINK it shouldn't matter, but I will file
that away in my mind.

Hello All,
I've searched but did not find an answer to this question. What does an _
(underscore) prefix on a Java variable signify?

The compiler doesn't care. It is a convention - some use it to signify
local variables (as opposed to fields which are "global" inside the
class). This helps the reader to know the scope of the variable.

Eclipse knows enough about your program to be able to color code the
two kinds differently which is very helpful. It is subtle but still
extremely helpful.

Actually I have looked at some code and found it strange in some way,
and after a while I found that a constant had been named like a field in
CamelCase instead of THE_USUAL_CONSTANT_SYNTAX. Fixing it made the
strangeness go away :)
