On this document we will be showing a java example on how to use the isFile() method of File Class. This method tests whether the file denoted by this abstract pathname is a normal file. A file is normal if it is not a directory and, in addition, satisfies other system-dependent criteria. Any non-directory file created by a Java application is guaranteed to be a normal file.

Where it is required to distinguish an I/O exception from the case that the file is not a normal file, or where several attributes of the same file are required at the same time, then the Files.readAttributes method may be used.


SecurityException – If a security manager exists and its SecurityManager.checkRead(java.lang.String) method denies read access to the file.
