/*****************************************************************************

 * Write class to validate credit card number using LUHN Formula(Mod 10)

 * Algorithm to validate check digits:

 * 1 - Beginning at the rightmost digit, moving right to left, sum the digits.

 * 2 - For every 2nd digit(from right), double value first, then sum

 * the value of each digit in the doubled number.e.g 6 -> 12, add 1 + 2

 * 3 - Sum for all digits

 * 4 - Take Sum modulo 10, if equal 0, then return true, else false.

 * Ex. "6314", Right->Left digits: 4, (2*1), 3, (2*6), so

 * Sum = (4) + (0+2) + (3) + (1+2) = 12, MOD10(12) = 2, so false

as they used while(true)... it goes to infinity

 

no it will struct in between as there is a sync used which will have lock and deadlock may occur process will for each other on same obj.

yep... in-proper output vasthundhi...

 

sometimes blocking with few values...

 

created a new project and tested it

 * Write class to validate credit card number using LUHN Formula(Mod 10)

 * 1 - Beginning at the rightmost digit, moving right to left, sum the digits.

 * 2 - For every 2nd digit(from right), double value first, then sum

 * the value of each digit in the doubled number.e.g 6 -> 12, add 1 + 2

 * 3 - Sum for all digits

 * 4 - Take Sum modulo 10, if equal 0, then return true, else false.

 * Ex. "6314", Right->Left digits: 4, (2*1), 3, (2*6), so
