Sum of numbers not divisible by 3

Where is my wrong?)

package en.codegym.task.pro.task04.task0407; /* Sum of numbers not divisible by 3 */ public class Solution { public static void main(String[] args) { int number = 1; int sum = 0; while(number <= 100){ sum += number++; if((sum % 3) == 0){ continue; } System.out.println(sum); } } }

sorry,the code should be like this: while (number <=100){ if(number%3==0){ continue; } sum +=number; } the reason your code is not working is beacuse: firstly,if the "number" is divisable by 3 it needs to be avoided,but your code was checking if the "sum" was divisable by 3. secondly,you used "sum += number" before the "continue" statement.So your code calculates the "sum" before reaching the "continue" statement.

as a fun fact... you even won't need if conditions and modulus if you use a double counter variable like

int sum = 0;
for (double i = 1; i <= 100; i += 1.5) {
    sum += (int) i;
}

However I wouldn't code it this way as double isn't really precise enough and this approach also is slightly slower. I'd code it similar as you showed us here just with a for loop and without continue statement.

it should be (number%3==0) in the if condition.
