These are by far the best tutorials i have found on the web, even though they start out pretty slow, that's a good thing, it keeps you from missing anything. Keep up the good work Travis!

[SecTechie]

Thanks. Now I actually understand what polymorphism is. Nobody really explained it. This is straight forward. Thanks.

Etymology of the term *polymorph*:

_It comes from the greek roots "poly" (many) and "morphe" (form)._

[jamiemarcum]

My brain is exploding with all this knowledge! 

[cuberwillima]

You have some great tutorials, keep it up man! What are you planning to cover up in the future?

[mybringback]

@simran55901 what database are you trying to connect to?

[emikohikari]

Thanks! :) You made it so simple to understand! Haha

[seangSTM]

Awesome tutorials!

One slightly non-JAVA related question - what program are you using to take your screen capture videos?

[simrandotdev]

@mybringback MySQL . I just meant that there are no tutorials on JDBC, its a really important topic to consider in swing applications .

[Bnks]

will this only work if the type class is absract or will a normal class work too?

[simrandotdev]

Hey @Travis plzzz do JDBC too in Java . Its the only missing topic that no one covers in Video tutorials ..

If the declaration type is Car and the construction method is Toyota(), but the Toyota class has a method that Car doesn't, can you call that method.
ex: Car c4 = new Toyota;
c4.dontStop(); //Method from Toyota, but not car

[IsraelCohen]

Stop cut the Video all the time. its Annoying
But you still huge. :)
Thank you Because of you I learned a lot

[vladandrei]

What's the difference between an interface and an abstract class? Besides the fact that you can extend only 1 class and implement multiple interfaces?

What happens if you call .speak() on a Ford object, if you do Ford c3 = new Ford() instead of Car c3 = new Ford()?

[Minddrops]

i use Netbeans but it seems that eclipse is better

[AttacksOnYaks]

while i was doing this tutorial, i seen honda, toyota, and ford commercials

[bboyhope]

no, i don't know what you mean by "peeps".

[Gasert_The_Great]

I believe you can't. Don't quote me on this, but I think you can retype your 'c4' - you can do "(Toyota)c4.dontStop();" That way your c4 becomes Toyota instead of Car, and you can use it, but it's awful when you want it in an ArrayList.

[shashwatkhanna]

Dude, Toyata is a Car .

Not Toyota is somewhat of a car
