列表自定义计数器

我一直想创建具有自己的计数器的自定义列表样式。我现在遇到的问题是计数器不是增加 1，而是增加 2。

这是一个例子：输出：第一个列表计数器是 2，第二个列表计数器是 4。

\documentclass{article}

\usepackage{listings}

\usepackage{xcolor}
\usepackage{caption}

% Colors
\definecolor{captioncolor}{cmyk/RGB/HTML}{0,0,0,.4/181,181,181/B5B5B5}
\definecolor{backgroundcolor}{rgb}{0.95, 0.95, 0.92}
\definecolor{commentcolor}{rgb}{0.55, 0.55, 0.55}
\definecolor{identifiercolor}{rgb}{0, 0, 0}
\definecolor{keywordcolor}{rgb}{0, 0, 0.5}
\definecolor{numbercolor}{rgb}{0, 0, 0}
\definecolor{stringrcolor}{rgb}{0, 0.5, 0}

\newcounter{javacounter}
\stepcounter{javacounter}

\DeclareCaptionFont{white}{\color{white}}

\DeclareCaptionFormat{listing}{\colorbox{captioncolor}{\parbox{\dimexpr\linewidth-2\fboxsep\relax}{#1#2#3}}}
\captionsetup[lstlisting]{
    format = listing,
    labelfont = white,
    textfont = white
    }
    
\lstdefinestyle{Java}{
    basicstyle = \linespread{1.1}\mdseries,
    backgroundcolor =  \color{backgroundcolor},
    breaklines = true,
    commentstyle = \color{commentcolor},
    identifierstyle = \color{identifiercolor},    
    keywordstyle = \color{keywordcolor},
    language = Java,
    literate =
        {\_}{}{0\discretionary{\_}{}{\_}}
        {Ä}{{\"A}}1
        {Ö}{{\"O}}1
        {Ü}{{\"U}}1
           {ä}{{\"a}}1
           {ö}{{\"o}}1
        {ü}{{\"u}}1
        {ß}{{\ss}}1,
    morekeywords = {assert},
    numbers = left,
    numbersep = 5pt,
    numberstyle=\color{numbercolor},
    showspaces = false,
    showstringspaces = false,
    showtabs = false,
    stringstyle=\color{stringrcolor},
    tabsize = 4,
    title = Java~(\thejavacounter):~\lst@@caption\stepcounter{javacounter},
    xleftmargin = \parindent
    }
\begin{document}
\begin{lstlisting}[style = Java]
public static void main(String[] args) {
}
\end{lstlisting}
\begin{lstlisting}[style = Java]
public static void main(String[] args) {
}
\end{lstlisting}
\end{document}

提前致谢！

这将创建一个java移动\stepcounter外部的环境lstlisting。请参阅手册第 43 页。

\definecolor{numbercolor}{rgb}{0, 0, 0}
\definecolor{stringrcolor}{rgb}{0, 0.5, 0}

\newcounter{javacounter}

\lstnewenvironment{java}{\stepcounter{javacounter}%
  \lstset{style=Java}}{}

\DeclareCaptionFont{white}{\color{white}}

\DeclareCaptionFormat{listing}{\colorbox{captioncolor}{\parbox{\dimexpr\linewidth-2\fboxsep\relax}{#1#2#3}}}
\captionsetup[lstlisting]{

    tabsize = 4,
    title = Java~(\thejavacounter):~,

\begin{document}

\begin{java}
public static void main(String[] args) {
