Consider the following Country class: public class Country{ String name; Integer population; Rewrite this class so that (i) it has a constructor that takes TWO inputs (a string and a number) and sets the object's state accordingly, (ii) it implements the Comparable interface so that two Country objects can be compared, and (ii) once the name is set it is never allowed to be changed again. Here is how Country objects should be compared. Let c1 and c2 be two Country objects. c1 < c2 when c1's population is less than c2's population; if they have the same population, then c1 < c2 when c1's name is alphabetically less than c2's name. Finally, c1 is equal to c2 when they have the same population and the same name.

Consider the following Country class:
public class Country{
String name;
Integer population;
Rewrite this class so that (i) it has a constructor that takes TWO inputs (a string and a
number) and sets the object's state accordingly, (ii) it implements the
Comparable interface so that two Country objects can be compared, and (iii) once
the name is set it is never allowed to be changed again.
Here is how Country objects should be compared. Let c1 and c2 be two Country
objects. c1 < c2 when c1's population is less than c2's population; if they have the
same population, then c1 < c2 when c1's name is alphabetically less than c2's name.
Finally, c1 is equal to c2 when they have the same population and the same name.
