Question

1)Your program will get numbers (int) from the user. Do this in a while loop so that you keep getting more numbers.
If the number is a multiple of 3 or 5, do nothing (use the "continue" command for this)
If the number is -99 then exit the loop
All other numbers should be added to the total (yes, you're making a total of all of the numbers)
After you exit the while loop print out the total

my code

package postMarchBreak;
import java.util.Scanner;

public class While99 {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

System.out.println("pick a few numbers and type -99 to stop");

while (true){
int num = sc.nextInt();
int sum = 0;

if (num==-99)
break;

if(num%3 == 0 || num%5 == 0){
continue;








}
sc.close();
}
}

}

how can I add up all the numbers that aren't multiples of 3 or 5

Answer 1

if(num%3 == 0 || num%5 == 0){
continue;
} else {
sum += num
}

Answer 2

i need to add the sum of all the numbers but what you suggested is just printing what I typed

Answer 3

clearly you do not know what the += operator does. It means sum = sum + num. That is, it adds up all the numbers that failed the divisibility test.

At the end of the loop, just print the value of sum.
