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; } }

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