Insert Bash code with coloration into my latex report

Question

I am writing a long report and I need to include some codes I programed. I would like present my code with coloration, as we can have in some text editor (and not using verbatim).

I need the coloration mode for two kind of languages (coloration given can be totally different, no problem with that):

• Bash language
• (Java language)<= Already have it, thanks!

Thank you in advance for your help.

*concerning the coloration itself, we can consider as simple example linux text editor.

Answer 1

Not contradicting anything in JoG's answer:

\documentclass{article}
\usepackage{xcolor}
\usepackage{listings}
\lstset{basicstyle=\ttfamily,
  showstringspaces=false,
  commentstyle=\color{red},
  keywordstyle=\color{blue}
}

\begin{document}

\begin{lstlisting}[language=Java,caption={Java version}]
public class HelloWorld {
   // Here's the main class
   public static void main(String[] args) {
       System.out.println("Hello, world!");
   }
}
\end{lstlisting}

\begin{lstlisting}[language=bash,caption={bash version}]
#!/bin/bash
echo "Hello, world!"
\end{lstlisting}

\end{document}

Answer 2

for java i use the listings package with following style:

\definecolor{javakeyword}{rgb}{0,0,0.5}
\definecolor{javastring}{rgb}{0,0.5,0}
\definecolor{javacomment}{rgb}{0.5,0.5,0.5}
\lstdefinestyle{java}{
   language=Java,
   showspaces=false,
   showstringspaces=false,
   basicstyle=\ttfamily,
   columns=flexible,
   stringstyle=\color{javastring},
   keywordstyle=\color{javakeyword}\ttfamily\textbf,
   commentstyle=\color{javacomment}\ttfamily\textit
 }

which i then use like

\begin{lstlisting}[float,style=Java,caption={Correct Logging example},label=lst:logging]
  private static final Log log = LogFactory.getLog(MyClass.class);

  public void doSomeStuff(Stuff stuff) throws StuffException {
      checkNotNull(stuff,"stuff should not be null");
  }
\end{listlisting}
