@title Themes and styles

@content listings does not provide any themes by default, but can be configured extensively.

\begin{lstlisting}[
    language=Java,
    basicstyle=\footnotesize\ttfamily,
    breaklines=true,
    keywordstyle=\color{ForestGreen},
    commentstyle=\color{DarkGray},
    literate={ö}{{\"o}}1
]
% …
\end{lstlisting}

Have a look at the \lstset command for creating your own themes.

• Enable special characters via the literate option.
• Activate syntax highlighting by stating the programming language Java.
• Number the code lines.
• Set the basicstyle to a proper mono-spaced font (\ttfamily \small)
