My issues: 1) I know I'm suppose to loop through each element of fahr[i] & compare each element to get: 1. above avg, 2. equal to avg, 3. below avg, but I a) don't know if my loop is correct  b) what to put in the ( ) of System.out.printf(what do I put here?, variable) relevant java code to 1): System.out.println("Above Average:"); int above = 0; //count above avg int below = 0;//count below avg for (i = 0; i < fahr.length; i++) if (fahr[i] > sumF) above++; if (fahr[i] < sumF) below++; } System.out.printf(       , above); System.out.println(); System.out.println("Equal to Average:"); System.out.printf(    , above);  System.out.println("Below Average:");  System.out.printf(     , below);  System.out.println(); 2) All output needs to be right-justified & aligned by decimal point.
