Make a function which will not return null instead return an empty array you can go through below code to understand.

    public static String[] getJavaFileNameList(File inputDir) {

        @Override
        public boolean accept(File current, String name) {
            return new File(current, name).isFile() && (name.endsWith("java"));
        }
    });

    return files == null ? new String[0] : files;
}
