Prefix Sums-CountDiv

Here is another codility problem solution from the codility lessons (CountDiv-Compute number of integers divisible by k in range [a..b].) due to the copy rights I can't copy the content of the problem here so to view the problem description click here.

class Solution {
	public int solution(int A, int B, int K) {
		// write your code in Java SE 8
		int count = 0;
		int div1 = 0;
		int div2 = 0;

		div1 = A / K;
		div2 = B / K;
		count = div2 - div1;
		if (A % K == 0) count++;

		return count;
	}
}
