public class repetition
{
   public static void main(String[] args)
   {
       int result = 0;  
      
       for(int i=7; i<=77; i = i+7)
       {
  
           result = result + i;
       }

       System.out.println("sum is= " + result);
  
       System.out.println("\nsum from for method call = " + sum (77));
       System.out.println("\nsum from while method call = " + sum_while (77));
       System.out.println("\nsum from do-while method call = " + sum_doWhile (77));
   }
  
   public static int sum (int n)
   {
       int sum = 0;
      
           for(int i=7; i<=n; i = i+7)
           {
               sum = sum + i;
           }
           return sum;
   }
  
  
   public static int sum_while (int n)
   {
       int sum_while = 0;
       int j = 7;
      
       while(j<=n)
       {
           sum_while = sum_while + j;
           j = j+7;
       }
           return sum_while;
   }
  
  
   public static int sum_doWhile (int n)
   {
       int sum_doWhile = 0;
       int k = 7;
      
       do{

           k = k+7;
       }while(k<=n);
       return sum_doWhile;
