Create a menu-driven DigitExtractor application that prompts the user for an integer and then displays the ones, tens, or hundreds digit of the number. This program must have two classes: DigitExtractor and Num. The DigitExtractor class should contain the main() method. The main() method should prompt the user for an integer and this number should be passed to the constructor in the Num class. The Num class should contain the constructor, the wholeNum() method which should return the whole number to the main() method, the onesPlace() method which should return the ones digit to the main() method, the tensPlace() method which should return the tens digit to the main() method, and the hundredsPlace() method which should return the hundreds digit to the main() method.. This means that the DigitExtractor class should include a Num object to call the methods in the Num class.

Sample I/O:

Enter an integer: 56789

(W) hole number.

(O) nes place number.

(T) ens place number.

(H) undreds place number.

The hundreds place digit is:7

(W) hole number.

(O) nes place number.

(T) ens place number.

(H) undreds place number.

The whole number is: 56789

(W) hole number.

(O) nes place number.
