In Java, you can get the length of the string "hello" with this statement: ??

5/2 = 2 // 2 fits twice in 5
5%2 = 1 // remainder - whole number after division
5 = 2*2 + 1
--------------
2/5 = 0 // 5 fits zero times in 2
2%5 = 2 // remainder - whole number after division
2 = 0 +2

5%2 question is either bugged or I'm seriously misunderstanding what a modulo does when I get the answer 5 :D If 2 were the right answer it should be 2%5, no? :D

% here, stands for modulo, which returns the remainder of the division of two numbers
so for example
the result of 6 modulo 2 would be 0 (there is nothing left over from 6/2)
7%2 = 1 (you can divide 7 by 2 three times and there would be 1 left over)

My question was "what is the evaluation of 5%2" and the answers were 1, 2, 2.5, 3 :D I mean, 5 but what the heck :D

the answer would be 1 because that will be the remainder when we divide 5 by 2.
and modulo operator gives us the same.
