java for loop sum and average of range -

i have calculated sum of loop range, not know how count , average solution. must done without ifs. loop:

//defining variables         // constants & variables here int i; int numstart; int numend; double sum = 0; double average=0; double loopcount=0; system.out.print("enter start number: "); // keep print line open numstart = console.nextint();  system.out.print("enter end number: "); numend = console.nextint();          //enter thevalue         (i = numstart; <= numend; i++ )         {             sum = sum + i;             loopcount = numend - numstart;             average = sum+1 / i;           }         system.out.println();         system.out.println( "sum is: " + sum);         system.out.println();         system.out.println( "average is: " + average);         system.out.println(); 

    (i = numstart; <= numend; i++ )     {         sum = sum + i;         loopcount++;     }     average = sum / loopcount;
