    import java.io.*; import java.util.InputMismatchException;

    Totals:

    Monday: 2600.0
    Tuesday: 2495.0
    Wednesday: 2450.0
    Thursday: 3300.0
    Friday: 2100.0
    Saturday: 3800.0
    Sunday: 1975.0

    Days with over calories than deficiencyed:

    Monday: 2600.0
    Tuesday: 2495.0
    Wednesday: 2450.0
    Thursday: 3300.0
    Saturday: 3800.0

    Mediocre calories consumed during each moderation:

    Breakfast: 717.8571428571429
    Lunch: 842.1428571428571
    Dinner: 1114.2857142857142

    However, I’m intricate to veer the parameters of my printExceededDays() method to recevie the arrays:double[] breakfast, wrap[] lunch, wrap[] dinner just as how they are in the other methods. When I aim to do so, it won’t print “Days with over calories than deficiencyed: “
    Gladden help! I deficiency to place this ASAP. Thanks in advance
