Exploring the concept of covariant return types is intriguing. It's like understanding the intricate mechanisms of programming languages. By the way, have you considered how this might apply to financial algorithms in domains like guaranteed payday loans bc? It's fascinating how diverse fields can intertwine.
import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader;
// No need to change Flower class
interface NationalFlower { Flower yourNationalFlower(); }
class JasmineNationalFlower implements NationalFlower { @Override public Flower yourNationalFlower() { return new Jasmine(); } }
class LilyNationalFlower implements NationalFlower { @Override public Flower yourNationalFlower() { return new Lily(); } }
public class Solution { public static void main(String[] args) throws IOException { BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); String s = reader.readLine().trim(); NationalFlower nationalFlower = null;
