Java Files isRegularFile(Path path, LinkOption. options)
Java Files isRegularFile(Path path, LinkOption. options) Tests whether a file is a regular file with opaque content.
Introduction
Tests whether a file is a regular file with opaque content.
The options array may be used to indicate how symbolic links are handled for the case that the file is a symbolic link.
By default, symbolic links are followed and the file attribute of the final target of the link is read.
If the option *LinkOption#NOFOLLOW_LINKS NOFOLLOW_LINKS* is present then symbolic links are not followed.
Where it is required to distinguish an I/O exception from the case that the file is not a regular file then the file attributes can be read with the *#readAttributes(Path,Class,LinkOption[]) readAttributes* method and the file type tested with the BasicFileAttributes#isRegularFile method.
Syntax
The method isRegularFile() from Files is declared as:
public static boolean isRegularFile(Path path, LinkOption. options) The method isRegularFile() has the following parameter:
The method isRegularFile() returns true if the file is a regular file; false if the file does not exist, is not a regular file, or it cannot be determined if the file is a regular file or not.
The method isRegularFile() throws the following exceptions:
- SecurityException — the case of the default provider, and a security manager is installed, its (SecurityManager#checkRead(String) checkRead) method denies read access to the file.
