In Bitcoin Whitepaper ( https://bitcoin.org/bitcoin.pdf ) on page 7, there is a C code snippet. The style, font and the size is very neat and proper. How can I apply this kind of style for my java code in TexStudio ( I am using TexLive)?

This is my java code:

import java.math.*;

public class successAttackerProbability {

public double calculateSuccessProbability(double q, int z) {
    int i, k;
    double p = 1.0 - q;
    double lambda = z * (q / p);
    double sum = 1.0;
    for (k = 0; k <= z; k++) {
        double poisson = Math.pow(Math.E, -lambda);

        for (i = 1; i <= k; i++)
            poisson *= lambda / i;
        sum -= poisson * (1 - Math.pow(q / p, z - k));

    }
    System.out.println(sum);
    return sum;

}

public static void main(String[] args) {
    successAttackerProbability successAttackerProbability = new successAttackerProbability();
    successAttackerProbability.calculateSuccessProbability(0.1, 1); // q =0.1 and z = 1
    successAttackerProbability.calculateSuccessProbability(0.1, 2);
    // ..
    successAttackerProbability.calculateSuccessProbability(0.1, 10);

}

}

    Why not? Could you add some code and descripe your problem with it? A small minimal working example (MWE), that illustrates your problem would be great.

  • Well, I just did it with $ \lstinputlisting{successAttackerProbability.java} $ , that's it, but I want the style like in the whitepaper.

    (*describe. ). - Does \lstset{basicstyle=\ttfamily} see daleifs answer solves your style problem? - Question without working code are harder to solve... compilable minimal code, starting with \documentclass and ending with \end{document}, helps a lot.

  • It solves my problem regarding to font color. Now, I have to change the font. Do you have any examples? If not, I will google :)

    ttfamily is the font or i'm wrong? - RelatedSetting up specific font for use in listings

That looks like plain verbatim, or the listings package with the basicstyle set to contain \ttfamily.

Example

\documentclass[a4paper]{article}
\usepackage[margin=3cm]{geometry}
\usepackage{listings}
\lstset{
  language=JAVA,
  basicstyle=\ttfamily\small,
%  columns=flexible,
  breaklines,
  breakatwhitespace,
}
\begin{document}

\begin{lstlisting}
import java.math.*;

public class successAttackerProbability {

public double calculateSuccessProbability(double q, int z) {
    int i, k;
    double p = 1.0 - q;
    double lambda = z * (q / p);
    double sum = 1.0;
    for (k = 0; k <= z; k++) {
        double poisson = Math.pow(Math.E, -lambda);

        for (i = 1; i <= k; i++)
            poisson *= lambda / i;
        sum -= poisson * (1 - Math.pow(q / p, z - k));

    }
    System.out.println(sum);
    return sum;

}

public static void main(String[] args) {
    successAttackerProbability successAttackerProbability = new successAttackerProbability();
    successAttackerProbability.calculateSuccessProbability(0.1, 1); // q =0.1 and z = 1
    successAttackerProbability.calculateSuccessProbability(0.1, 2);
    // ..
    successAttackerProbability.calculateSuccessProbability(0.1, 10);

}
\end{lstlisting}

\end{document}

See the listings package manual for details.
