I'm trying to create a LaTeX document with several blocks of source code included. Between these blocks of code I want to add in a few lines of whitespace. I have tried using \\ however this didn't work.
Here is what I have at the moment...
\lstset{language=Java, caption=ClassA.java}
\begin{lstlisting}
% My code
\end{lstlisting}
\\ % This is where I want to make some whitespace
\lstset{language=Java, caption=ClassB.java}
\begin{lstlisting}
% My code
\end{lstlisting}
\vspace{2cm} is usually good for these sorts of things; it will insert 2cm of vertical space. In certain situations (I forget exactly when) you need to use the starred version, \vspace*{2cm}. Obviously, adjust the length as necessary.
Try either \smallskip, \medskip or \bigskip. Or use \vspace.
\\ ends a line. If there is no line preceding it, you cannot end it either.
A simple hack for this (in situations where you cannot use \vspace, is to print one space character and then the new line: \ \\.
If you have an line Ending \\ you can type the wanted distance in brackets.
So \\[4cm] will produce a whitespace of 4 cm.
At the beginning of a section \vspace* is a better solution. You can only use a line ending there by putting something in front (like ~\\) but this will probably cause an underfull hbox warning.
