对于循环，获得数字的总和

Question

我制作了一个for循环，生成一个从300到200的数字列表，其数量为11或13倍。我的问题是，我怎样才能得到这些数字的总和？

package Week3.Yedkois;

public class Project1 {

    public static void main(String[] args){


        for (int i = 300; i > 200; i-= 1){ // countdown from 300 to 200

            boolean num = (i % 11 == 0 || i % 13 == 0) && !(i % 11 == 0 && i % 13 == 0); // multiples of 11 and 13 but not booth.

            if (num == true)

            System.out.printf("%-5s", i );

        }   
   }



    }

public static void main(String[] args){

        int sum = 0; // variable to store sum

        for (int i = 300; i > 200; i--){ // countdown from 300 to 200

            boolean num = (i % 11 == 0 || i % 13 == 0) && !(i % 11 == 0 && i % 13 == 0); // multiples of 11 and 13 but not booth.

            if (num == true) {

               System.out.printf("%-5s", i );
               sum += i; // Calculate sum for every matched number
            }
        }   
        System.out.printf("Sum = %-5s", sum);
   }
