Question :

Write a Java program that asks the user for a EAN13 and validates it as either correct or incorrect (display a message accordingly).

Your program should continue to run, to validate multiple EAN13 numbers, until the user decides to exit the program, by entering 'Q' or 'Quit'.

Comment your code and use procedural decomposition problem solving techniques.

If EAN13 is 4006381333931 the check code is computed as follows:

Calculation
First 12 digits of the barcode	4	0	0	6	3	8	1	3	3	3	9	3
Weights	1	3	1	3	1	3	1	3	1	3	1	3
Multiplied by weight	4	0	0	18	3	24	1	9	3	9	9	9
Sum												89

The nearest multiple of 10 that is equal or higher than the sum, is 90. Subtract them: 90 - 89 = 1, this is the last digit of the barcode.
