    Default RainFall Programming

    I have written program for rainfall that will store and give total, average, least and most. The program stores the input of rainfall for each month. However at the end it suppose to print out the month with the least and most rainfall. I am getting this on the print for
    The month with the most rainfall: [Ljava.lang.String;@79a7bd3b
    and for
    The month with the least rainfall: [D@7378aae2[Ljava.lang.String;@79a7bd3b
    . What have i done wrong?

    The String in the printout: [Ljava.lang.String;@79a7bd3b is the String returned by a String array's default toString() method. The compiler generates a call to the toString() method when an array is concatenated to a String.
    [D@7378aae2 is from the default toString() method for an array of doubles.

    There normally is no reason to print the full contents of an array, except for when debugging.
    Did you intend to index into the arrays to extract an element to show?
    If you don't understand my answer, don't ignore it, ask a question.

    If the data you want to show is an element in an array, the code needs to index into the array to get it:
    theArray[theIndex]
