Java Code in a paper

Question

I am writing a paper and would like to include some of my "real-world" Java code. What is the best way to accomplish this? I would like to see two templates:

1. My explanation to the right of my Java Code in a column fashion
2. All of my Java code pasted in one block and then a description afterwards

I think 2 is probably the best way to go for simplicity.

Answer 1

You can use the listings package like this sample:

\documentclass{article}

\usepackage{filecontents}
\begin{filecontents*}{_myperl.pl}
#!/usr/bin/perl
while (<@ARGV>)
  { $sum += 1/($_*$_); }
print sqrt(1/$sum), "\n";
\end{filecontents*}

\usepackage{listings}
\begin{document}
\section{listings}
\lstset{language=Perl}
\lstinputlisting{_myperl.pl}
\end{document}

Here I have included the sample java code in the document, but you will probably want to keep it in a separate file.
