    Question How to develop a class MonthDate to print out the following output ?

    How to develop a class MonthDate to print out the following output ? I know one of the method is to use toString, but how?


    Code:

    import java.util.Arrays;
    public class SortMonthDate {
    public static void main(String[] args) {
    MonthDate[] mdates = new MonthDate[5];
    mdates[0] = new MonthDate(22, 7);
    mdates[1] = new MonthDate(25, 8);
    mdates[2] = new MonthDate(25, 6);
    mdates[3] = new MonthDate(28, 9);
    mdates[4] = new MonthDate(5, 9);
    print(mdates);
    Arrays.sort(mdates);
    print(mdates);
    }

    static <T> void print(T[] a) { // generic method
    for (T t : a) {
    System.out.printf("%s ", t);
    }
    System.out.println();
    }
    }


    Expected Output:
    22/7 25/8 25/6 28/9 5/9
    28/9 5/9 25/8 22/7 25/6

    What is the current output?

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    Here is what I have tried :

    public class MonthDate {

    public String toString() {
    return String.format("%02d/%02d", this.day, this.month);
    }
    }

    And I have no idea to continue

    Here is what I have tried
    Can you copy and post here what is printed out when the code executes so we can see it?
    Add comments explaining what is wrong with it.
