Answer 1

Object u can't call static method..

Remove static:

public class Program
{
public static void main(String[] args) {
Neo u = new Neo();
System.out.print(u.hello());
}
}
interface Dusk {
public int hello();
}
class World implements Dusk {
public int hello() {
return 10%5;
}
}
class Neo extends World {
public int hello() {
return 5;
}
}

Answer 2

You declared static method hello() without implementation.
Static and final methods should be implemented where they are declared.
