Scanner for long integer, Exception in thread “main” java.util.InputMismatchException

Question

I am at the last step to finalize my program, however whenever I enter my integer (long) I get a input mismatch:

Compiler message: \"Exception in thread \"ma         


        

Answer 1

The maximum Integer value is 2147483647. Instead, use long:

long credNumber = kbd.nextLong();

or better use String for credit card number:

String credNumber = kbd.nextLine();
