编辑：整个方法是：

        public static String[] singlemultiplet(String filename, int numofzeros) throws IOException {//isolate notes between brackets
    Scanner inputmeasure = new Scanner(new DataInputStream(new FileInputStream(filename)));
        InputStream is = new BufferedInputStream(new FileInputStream(filename));
            BufferedReader bReader = new BufferedReader(new InputStreamReader(is));
            StringBuffer sbfFileContents = new StringBuffer();
            String line = null;
            int lineCount = 0;
    int j = 0;
        int[] cmn = new int[countbrackets(filename)];
        String[] numbers = new String[40];
        String[][] matrix = new String[20][120];
        String[][] matrix2 = new String[20][120];
        String[][] matrix3 = new String[20][120];
            line = inputmeasure.useDelimiter("\n").next();
            Scanner s = new Scanner(line).useDelimiter("U");
            matrix[0][0] = s.useDelimiter("\r").next();
            String ubar = "U|";
            matrix2[0][0] = matrix[0][0].replace("\\),","U").replaceAll("\\)","U").replace(ubar,"U");
            matrix3[0][0] = matrix2[0][0].replace("|","U");
            Scanner s2 = new Scanner(matrix3[0][0]).useDelimiter("U");
            String brack = "(";
            String[] multiplet = new String[countmultipletsandmeasures(filename) + numofzeros];
            String[] multiplet2 = new String[countmultipletsandmeasures(filename) + numofzeros];
            Arrays.fill(multiplet, "");
            int cmampluszeros = countmultipletsandmeasures(filename) + numofzeros;
             for (int i = 0; i < cmampluszeros; i++)
             {
              matrix3[0][0] = s2.useDelimiter("U").next();
              multiplet[i] = matrix3[0][0];

             }
             lineCount++;
                    sbfFileContents.append(line);

            String strContent = sbfFileContents.toString();
    try {
        return multiplet;
    } finally {
        is.close();
    }
}

程序给出了块

multiplet[i]

作为

这是正确的。但当我试着读入时： A、 A，A，B，B，C，B，B，C，Bb，Bb，Cb | A，B，C，D，E，F，G，|，A，，，，，，，，，，，，，，，，，，我得到了一个非接触式的例外。正确的输出是：

multiplet: (A#,A#,A#
multiplet: ,(B#,B#,C#
multiplet: ,(B#,B#,C#
multiplet: ,(Bb,Bb,Cb
multiplet: A#,B#,C#,D#, E#,F#,G#,  
multiplet:   ,A,  , ,   ,  ,  ,  ,  ,  ,  , ,   ,  ,  ,

有人知道我为什么以及我应该做什么来获得正确的输出吗

调试将提供以下堆栈跟踪：

断点命中：thread=main，IOguitar.singlemultiplet，line=2769 bci=306 2769 matrix3[0][0]=s2.useDelimiterU.next

主[1]步骤

步骤完成：thread=main，IOguitar.singlemultiplet，line=2770 bci=322 2770多重态[i]=matrix3[0][0]
