Consider the following Country class. Write a comparator that defines an ordering on Country objects. Use lexicographic ordering on (name, area). That is it first compares names. If they are the same (ignoring case), then compare the area. API is on the last page. class Country {private String name; private int area; public Country (String n, int a) {name = n; area = a;} public string getName {} {return name;} public int getArea {} {return area;} public String costring {} {return name + " " + area;}} public class CountryTester {public static void main (String args) {Comparator comp =//your work goes here. ArrayList countries = new ArrayList(); countries.add(new Country ("a", 30)); countries.add(new Country ("b", 10)); countries.add(new Country ("a", 20)); Collections.sort(countries, comp); System.out.printin(countries);//prints [a 20, a 30, b 10]}}
