Bro you skipped over interfaces,I was expectiong you to cover that!!
-
I do that before to see the next tutorial.
public class DogList {
private Animal[] theList = new Animal[5];
private int i = 0;public void add(Animal d) {
if(i < theList.length) {
theList[i] = d;
System.out.println("Animal added at index "+i);
i++;
}
}
}I know it can have more stuff but i did that in 30 second more or less (its just change Dog for Animal)

i'm i the only one having this bad habit of liking thnewboston videos even before it starts?
-
YOU DON'T TELL ME WHAT TO DO, BOSS!
-
And with that last few seconds, bucky diverted me. Again!
-
Bucky, you are a big help. I am new this and JAVA is kicking my butt. Thank man. Please keep the video's coming…
-
guyz ..How do you know that u need to increment like this " +x" or like this x+ ??
-
Do people who work with programming ever use this??
-
What 500 videos is he talking abt?
-
Knock Knock XD
-
Can anyone explain this line : theList[i]=d;
-
and in the 59th tutorial, we started using uppercase naming conventions for classes! HOORAY!
-
hey guys is there any difference in the program using [ ] as shown in below? or does it have the same effect?
i mean using [ ] before "thelist"
private Dog thelist [ ] = new Dog [5];and using [ ] after "thelist"
private Dog [ ] thelist = new Dog [5]; -
Hmm… Dog objects array holding objects with the same object identifiers?
-
What's up with not using the default package and/or why does Bucky use it? What does that even mean?
-
Knocking on the door was perfectly timed as a ' Boss ' – situation, well done bucky 🙂
-
What if iI put the variable i as Static ??
-
can we get rid of thelist array ? is it necessary to put?
-
thanks a lot！love your tutorials

"we'll name it d. Short and sweet" – bucky 2009
-
Thank you, bucky for making these videos. They are awsome! After I watched your Javal tutorial 59, you said your 500 videos would come up. Could you tell me where they are? Thank you a lot!
-
Does the 'if' statement work like a 'while' loop?
-
Hey bucky.. Your vdos are great.. Thanks man!
Can you pls tell me in which video have u taught about Interfaces?? Also can you explain in a video with an example difference between interface/inheritance/abstract.. it is kinna confusing as in case of abstract class we need to implement its methods and also in case of interfaces.. Please correct me if i am wrong.. I wanna understand this badly and never get confused.. 😐
Thanks in advance..
-
Hi Bucky may I know your email Id please?
-
"We'll name is D for now… short and sweet." I'm really just curious as to whether that pun was intended. I guess we'll never know. LOL
-
Why does everyone say polymorphism is confusing? I'm 14 and I understand it just fine.

Hey, Bucky, would you publish some Objective C tutorial course? would be awesome!
-
Wait, dog and fish! Those are still food types! You have not escaped the food!
-
RIP tuna 🙁
-
Thank you, this was very helpful.

Dude I know this is beginner stuff – but no reason to teach bad coding standards… Like.. You wouldn't create a "DogList" .. you would create an interface for a List that is generic. You then make the actual list Implementing that interface. The list will then (if it is array-based) have to have an Object array; Object[] array = new Object[10]; That list will then be able to hold any kind of Object.. aaaaand you can make multiple different Lists that implement the same Interface (but instead might be referenced-based) and the two List would be of the same type since they implement the same interface.

How do i make the stuff that i coded ".exe"
-
Finally, you got rid of those stupid classes. They smelled like fish. Even though the "Fish" class still smells like fish
-
im watching 15 tuts/day. bucky, YOU ARE THE BEST, YOU SHOULD BE A TEACHER
-
i am looking forward for the file read and write tuts to start the register / first image page of my game 😉
-
FREAKING JAVA VEHICLE IS MAKING ME CRAZY!! haha
-
It is good if you make "i" a static variabile ?for more safety?
-
Link to 500th Video? :/
-
you make an array from "Dog.class", why that ?
-
you did not show as what is interface,would you please.
-
this is not even tutorial. This is hint.
I found that his tutorials are always tutorials and he don't actually shows real hints like this. 🙂
-
Hey Bucky, really love your videos, nobody explains these things as clear as you do. But there's one problem, you should teach people to respect Java naming conventions. By this I mean naming classes with capital letters, each new word in a variable name with capital letter and so on and so forth.

No…
