they didnt even teach some of these questions in previous lessons

I thought it was scanner.BufferedReader ?

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

i doubt this 5/2 gives 2.5 or does it, is it 2 or something

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

very nice java in the dance floor

% 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)

i didnt read anything about 5%2
