### Question:
FileHelper { public static boolean createFile(String path) { if (path != null && path.length() > 0) { try { File file = new File(path); if (!file.getParentFile().exists()) { file.getParentFile().mkdirs(); } file.createNewFile(); return true; } catch (Exception e) { logger.error("create file exception :" + path + ",Exception" + e.getMessage()); e.printStackTrace(); } } return false; }  static void handlerWithLine(File file, String encoding, ObjectHandler<String> handler); static void processWithLine(File file, String encoding, Collection<E> result, ObjectProcess<String, E> process); static int lineCounts(File file); static List<String> readLines(File file); static List<String> readLines(File file, String encoding); static String readContents(File file); final static boolean createFiles(File file); final static boolean createFiles(File file, boolean isReNew); static boolean write(File file, String str); static boolean write(File file, String str, String encoding); static boolean addWrite(File file, String str); static boolean addWrite(File file, String str, String encoding); static boolean copy(File resource, File target); static boolean copyFile(File file, File targetFile); static boolean cleanFile(File file); static boolean delete(File file); static List<File> listFile(File path); static List<File> listFileSuffix(File dirPath, String postfixs); static List<File> listFileName(File dirPath, String fileName); static List<File> listFileNameIgnoreCase(File dirPath, String fileName); static List<File> listFileFilter(File path, ObjectFilter filter); static List<File> listFileNameReg(File dirPath, Pattern pattern); static List<File> listFileWithHandler(File path, ObjectProcess<File, File> handler); static boolean createFile(String path); static String suffix(File file); static String fileHash(File file, String HashTyle); static String simpleEncoding(File file); static boolean zipDeCompress(File file, String zipFile); static boolean zipUnCompress(File zipFile, String path);  }### Answer:
@Test public void testCreateFile() { String basePath = TestUtil.path + "/temp"; FileHelper.createFile(basePath + "/temp1/test.dat"); FileHelper.createFile(basePath + "/temp1/temp2/temp3/test.dat"); }
