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

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
