    public static List getFilePath(String folderPath) {
        File folder = new File(folderPath);
        List filePathList = new ArrayList<>();
        String rootPath;
        if (folder.exists()) {
            String[] fileNameList = folder.list();
            if (null != fileNameList && fileNameList.length > 0) {
                if (folder.getPath().endsWith(File.separator)) {
                    rootPath = folder.getPath();
                } else {
                    rootPath = folder.getPath() + File.separator;
                }
                for (String fileName : fileNameList) {
                    filePathList.add(rootPath + fileName);
                }
            }
        }
        return filePathList;
    }
