JAVA获取文件名

    public static ArrayList<String> getFiles(String filePath) {
        ArrayList<String> la = new ArrayList<String>();
        File root = new File(filePath);
        File[] files = root.listFiles();
        for (File file : files) {
            if (file.isDirectory()) {
                getFiles(file.getAbsolutePath());
            } else {
                la.add(file.getAbsolutePath());
            }
        }

        return la;
    }
}
