have I missed a lesson or is the "length" keyword just a new concept ?

[tidus]

Great example of overriding, It's way clearer now :)

[TheGazanews]

once again you saved my day thank you so much but one quick question is developper use polymorphisme only in polymorphic array ?

[bongchi_]

I have a question, What makes a class "Super" class or "Sub" class or is it just a naming thing or is it when you extend a class, it makes that class a super class?

So does the object beetle become basically a subclass of Insect?

[sirburos]

Great video.  One thing, though, spiders aren't insects.  They're arachnids.

[physicsimpossible]

Nice video! But why NetBeans? Eclipse is better imo

[stephenwisniewski]

Hahahaha can't believe it is this simple

[vndosapp]

public class Beatle {
void perform(int index) {
String instrument[] = {"Riff Guitar", "Drums", "Bass", "Solo Guitar"};
System.out.println("Playing the "+instrument[index]);
}
}

[MrAirPork]

Hi i've a couple of questions
How does the Insect beatleObj = new Beatle() work? How different is it from Insect beatleObj2 = new Insect();

What does the allInsects.length do? How does it work

Lastly how does the overriding work? Does overriding always take priority over superclass's method?
