Question

Write a Java program using using WHILE loop to find the sum of all integers between 200 to 250 which are divisible by 7.

Sample Output:

Numbers between 200 and 250, divisible by 7:

203 210 217 224 231 238 245

The sum is: 1568

Typed Code:

public class Main
{
   public static void main(String[] args) {
   //initializing i as 200 and sum as 0
       int i = 200,sum = 0;
       System.out.println("Numbers between 200 and 250, divisible by 7:");
       //while loop will iterate till "i" value become bigger than 250
       while(i <= 250)
       {
       //if i value is divisible by 7
       if(i%7==0)
       {
       //printing the number
       System.out.print(i+"\t");
       //adding the number to sum
       sum = sum + i;
       }
       //increment i value
       i++;
       }
       System.out.println();
       //printing the sum
       System.out.print("The sum is "+sum);
   }
}
//code ended here
