code: private String[] Tokenizer2StringArray(String sourceStr, String strDot) {
      StringTokenizer st = new StringTokenizer(sourceStr, strDot);
      int size = st.countTokens();
      String[] strArray = new String[size];
      for (int i = 0; i < size; i++) {
        strArray[i] = st.nextToken();
      }
      return strArray;
    }
docs: 将StringTokenizer类型数据转化生成字符串数�?
  
  @param sourceStr 解析","间隔的字符串，变成字符串数组
  @param strDot
