Define a class called Country. A Country has populationSize, area, capital, currency, and abbreviation (2-3 letters taken from the country name). Define at least two constructors, at least two getter methods, at least two setter methods, and Override the toString() and the equals() methods. The equals() method must return true if the two countries have the same name and same populationSize and false otherwise. The abbreviation is the first letter and the second letter of the country name and must be generated automatically (e.g. if the country name is Palestine the abbreviation is PA, if the country name is Jordan the abbreviation is JO.) Write a main method, define an array of country objects, read countries data from the user, if two countries have the same abbreviation add the last letter from the country name to the abbreviation of the country inserted last. Display countries whose area is greater than 10000 km2.
