Resource
If this abstract pathname does not denote a directory, then this
method returns null
. Otherwise an array of strings is
returned, one for each file or directory in the directory. Names
denoting the directory itself and the directory's parent directory are
not included in the result. Each string is a file name rather than a
complete path.
There is no guarantee that the name strings in the resulting array will appear in any specific order; they are not, in particular, guaranteed to appear in alphabetical order.

Resource
If this abstract pathname does not denote a directory, then this
method returns null
. Otherwise an array of
File
objects is returned, one for each file or directory in
the directory. Therefore if this pathname
is absolute then each resulting pathname is absolute; if this pathname
is relative then each resulting pathname will be relative to the same
directory.
There is no guarantee that the name strings in the resulting array will appear in any specific order; they are not, in particular, guaranteed to appear in alphabetical order.

Resource
All platforms support file-modification times to the nearest second,
but some provide more precision. The argument will be truncated to fit
the supported precision. If the operation succeeds and no intervening
operations on the file take place, then the next invocation of the
method will return the (possibly
truncated) Resource.lastModified()
time
argument that was passed to this method.
