Java program that prints out numbers that are divisible by other numbers

Question

I have a program that reads two real numbers and then it prints out all the numbers between these two, that are divisible by 2 or 3 or 5. The program works fine, but when a use

Answer 1

Not really an answer, but with my low reputation score I am not permitted to post a comment.

If a number is divisible by 2, or 3, or 5 does not change if you add or subtract 30 (= 2* 3* 5) from that number. So you can count the matching numbers from 1 to 30, then compute how many blocks of 30 numbers are in your range, and then count the matching numbers that are not covered by those blocks.
