Write a Java class called Date that includes three fields year, month and day.
This class stores information about a single date (year, month and day). Your class should have constructor(s), accessors and mutators and it should implement the Comparable interface.
Years take precedence over months, which take precedence over days.
For example, Feb 19, 2016 comes after Nov 20, 2015.
The following class DateTest can be used to test the Date class that you wrote.
It creates a list of the birthdays of the first 5 U.S. presidents in random order and puts them into sorted order.
(Note: you can use Collections.sort() to sort your ArrayList after you implement the compareTo() method).
import java.util.*;
public class DateTest {
public static void main(String[] args) {
ArrayList<Date> dates = new ArrayList<Date>();
dates.add(newDate(4,13,1743)); //Jefferson
dates.add(newDate(2,22,1732)); //Washington
dates.add(newDate(3,16,1751)); //Madison
dates.add(new Date(10, 30, 1735)); // Adams
dates.add(newDate(4,28,1758)); //Monroe
System.out.println("birthdays = " + dates);
Collections.sort(dates);
System.out.println("birthdays = " + dates);
}
}
When you execute the following code it should print:
birthdays = [4/13/1743, 2/22/1732, 3/16/1751, 10/30/1735, 4/28/1758]
birthdays = [2/22/1732, 10/30/1735, 4/13/1743, 3/16/1751, 4/28/1758]
