What does "exclamation mark" (!) mean on xubuntu eviroment? Eclipse program. [message #1727488] Wed, 23 March 2016 06:58 Go to next message

Hi fellows.

I wanted to know what does the exclamation mark mean?

For example:

while(!try(second)) ..

Does it refer to any previous used information on my code?

Thanks.

In the absence of any context information I can only suspect that it refers to the boolean NOT operator, which turns
true into false and false into true.

This has nothing to do with XUbuntu. It's a language construct in C/C++
and Java (you give no context). You're learning to write code using
Eclipse? Such language-oriented question are better posted in forums
like javaranch.com and stackoverflow.com. Ask questions here about how
to download, install, set up and use Eclipse.

Best of luck!
