Showing two listings in a table side-by-side

Question

I wonder is there any possibility to show two different listings in one table side by side? Here is my code that only show one listening but how can I embed it in a table and another one?

EDIT: Even I have tried the mentioned links on below, I get a few errors while compiling the file. I also post my edited LaTeX code.

\begin{lstlisting}[
basicstyle={\scriptsize\ttfamily},

class PrintHelloThread ext Thread {
    void run(Dummy x) {
        out.println("Hello world")
    }
}

class X ext ProxifiedObject {
    PrintHelloThread thread

    void main(X x) {
        x.thread := new PrintHelloThread;
        x.thread.start(0);
        x.thread.join(0);
    }
}
\end{lstlisting}
\end{minipage}

Answer 1

As David said to do. In this case, I placed the result in a tabular. I also made the listings in \tiny, so as to make two side-by-side listings fit in the margin width.

In my case, I also placed them in boxes beforehand, so that my tabular code would look nice:

\begin{tabular}{|c|c|}
\hline
\stackinset{l}{-5pt}{t}{13\llength}{$\bullet$}{\listingA} &
\stackinset{l}{-5pt}{t}{ 7\llength}{$\bullet$}{\listingB} \\
\hline
\end{tabular}

EDITED to add little black circle to each listing. In this case, I superimposed them on the listing box with a \stackinset, defining the length of \llength to correspond to one line spacing in the tiny listing. Thus, a command like

\stackinset{l}{-5pt}{t}{13\llength}{$\bullet$}{\listingA}

indicated to place the bullet 13 lines down on the first listing.

Answer 2

Your example generated errors because color was not loaded, but other than that it basically worked. You don't need the tabular just two `minipages are sufficient. Some of your lines are too ong to fit side by side, but that's a separate issue.
