Sort list of threeMyDate(year,month,day) objects.
2. Steps to do

- Override compare(object1: T, object2: T) method and:
+ return zero if object1 is equal object2
+ a negative number if object1 is less than object2
+ a positive number if object1 is greater than object2

package com.javasampleapproach.objcomparatordata class MyDate (val year: Int, val month: Int, val day: Int) {
