This one is kind’a geeky, but I have to show it to you. I’m reading chapter three of my SCJP-book (Sun Certified Java Programmer) where I found this example (which won’t compile…it’s not meant to, it’s just an example 🙂 ) Read through the code, and pay special attention to the comments, I really like the last one
interface Sporty() {
void beSporty();
}
class Ferrari extends Car implements Sporty {
public void beSporty() {
// implements cool sporty method
// in a Ferrari-specific way
}
}
class RacingFlats extends AthleticShoe implements Sporty {
public void beSporty {
// implements cool sporty mehtod
// in a RacingShoe-specific way
}
class GolfClub { }
class TestSportyThings {
public static void main (String[] args) {
Sporty[] sportyThings = new Sporty[3];
sportyThings[0] = new Ferrari();
// Ok, Ferrari implements Sporty
sportyThings[1] = new RacingFlats();
// Ok, RacingFlats implements Sporty
sportyThings[2] = new GolfClub();
// Not ok, GolfClub does not implement Sporty
// I don't care what anyone says!!
}
}
As some of you might know, I have a saying that goes like this “Never coffee, never golf”. I’m starting to like this book
