add a method and call it multiple3or7(num) that gets an int number and returns true if the number is a multiple of 3 or 7.

Then, use that method inside your loop to count how many numbers are a multiple of 3 or 7. Match the formatting below.

>run Lab09 Enter a number: 10 2 -3 6 -7 10 -11 14 -15 18 -19 10: 6 multiple of 3 or 7
