In Java, implement the following program

Input: A non-negative integer via the command line

Output: The sum of all integers x in the range of [1, INPUT] such that x is divisible by 7

-- You should use FOR loop in your code

Example:

INPUT: 20 => RESULT = 21 (7 + 14)

INPUT: 21 => RESULT = 42 (7 + 14 + 21)
