I need this class completed in Java

Create a class named Time that contains integer fields for hours and minutes. Store the hours in military time, that is, 0 through 23. Add a function that displays the fields, using a colon to separate hours and minutes. (Make sure the minutes display as two digits. For example, 3 oclock should display as 3:00, not 3:0.) Add another function that takes an argument that represents minutes to add to the time. The function updates the time based on the number of minutes added. For example, 12:30 plus 15 is 12:45, 14:50 plus 20 is 15:10, and 23:59 plus 2 is 0:01. The Time constructor requires an argument for hours. The argument for minutes is optional; the value defaults to 0 if no argument is supplied. The constructor ensures that the hours field is not greater than 23 and that the minutes field is not greater than 59; default to these maximum values if the arguments to the constructor are out of range. Create a main() function that instantiates an array of at least four Time objects and demonstrates that they display correctly both before and after varying amounts of time have been added to them. Save the file as Time.java.
