For all files and paths, use the Files and Paths APIs from the java.nio.file package when possible.

B The following private fields:

$1$ A static constant path for the base directories, which are db sub tables relative to the project directory.

$2$ A path for the flat file, which is the table file structure in CSV format.

$3$ No fields for the degree, size, fingerprint, or any other fields $($unlike in previous modules$).$

C A $2-$ary constructor which takes a name parameter $($string$)$ and a columns parameter $($list of strings$).$

$1$ Create the base directories, if needed.

$2$ Initialize the path field by resolving the given name plus the $.$csv extension relative to the base directories.

$3$ If the flat file doesn$$t exist at the path field, create it$.$

$4$ Join the columns parameter into a header record $($line$)$ using commas $(,).$ Don$$t use quotation marks.

$5$ Create a list of records $($list of lines$)$ with the header as its only record.

$6$ Write the list of records to the flat file.

D A $1-$ary constructor which takes a name parameter $($string$)$ only.

$1$ Initialize the path field by resolving the given name plus the $.$csv extension relative to the base directories.

$2$ If the flat file doesn$$t exist at the path field, throw an illegal argument exception.

E A public clear method.

$1$ Read all records $($lines$)$ from the flat file into a list of records.

$2$ Clear all records from the list of records, retaining only the header.

$3$ Write the modified list of records to the flat file.

F Public methods for the following properties:

$1$ The name method which returns the name of the flat file, excluding the base directories and the $.$csv extension.

$2$ The columns method which returns the columns stored in the header of the flat file split using commas $(,).$

$3$ The degree method which returns the size of the list of columns which is returned by the columns method.

$4$ The size method which returns the number of records $($lines$)$ in the flat file, excluding the header.

$5$ The equals method which returns true if the parameter is any table with the same fingerprint $($as in previous modules$).$

$6$ Don$$t implement capacity or loadFactor, because this is a FileTable, not a DataTable.
