    Your content is great man, but clean up your style a little!
    Class Apples {
    public static void main( String[] args ) {
    Food bucky = new Food[2];
    bucky[ 0 ] = new Tuna();
    bucky[ 1 ] = new PotPie();
    for ( int i = 0; i < buck.length; ++i ) {
    buck[ i ].eat();

    does the toString method over power the override method when you call class them in the main class what should execute first ??

    Sorry to disagree with @Bob The Zealot, but the valuable part that explains polymorphism is from 4:38 to 7:02

    eat() isn't a proper food method. That belongs to the Animal and Person classes

    Polymorphism is one of the key concepts of advanced programming concepts

    from where can I copy/paste theses classes and superclass? I would like to run it on compiler and that makes me understand better

  24. Storystein Avatar

    Both my teacher and my classmates couldn't explain this properly to me. Now, I feel like I fully understand it. THANKS! Your explanation couldn't be any clearer.

    Good day Mr Bucky. Thank you very much for your tutorials on youtube about java programming. you have really help me a lot. I really appreciate your work. God Bless

    I hate to say this but EVERYONE sucks fucking balls at explaining polymorphism, I'm sorry but it NEVER gets explained properly why would we do food f = new tuna(); to print the tuna method? when we could just do tuna t = new tuna(); no one explains this!

  27. justin lopes Avatar

    Not sure, why ++x was used…Because meaning ++x means….add 1 before the first use of the "x" , which means it will start at array bucky[1] instead of array bucky[0]..Not sure how this loop worked. In earlier tutorials, about the math operators, this was explained…Not sure, why ++x was used instead of x++

    It seemed to me like Inheritance then why it's called Polymorphism?? Umm may be it's a bull-shit, stupid, dumb-ass (whatever you like to say) question but please someone help me.

  40. Kaysar777 Avatar

    I think, you can also use polymorphism if the classes you're referring to implement the same interface.
