what the shit. you don't know how to code but you're dicking around with reflection?

could still use help with this. atm im trying to figure out 1. why i'm getting errors:

Code

res = Reflection.filterMethods(this, getDeclaredMethods0(publicOnly));
if ((res = searchMethods(privateGetDeclaredMethods(true),
Method method = getMethod0(name, parameterTypes);

and 2. about abstract classes : I have an abstract class Game, and a class called BlackJack. BlackJack extends Game. in my GameConsole class, I have Game blackjack = new BlackJack(); how do i call methods from the BlackJack class?

or if i try:

Code

BlackJack test = new BlackJack();
test.playGame();

i get error:
Exception in thread "main" java.lang.NoSuchMethodError: BlackJack.playGame()V

if "playGame()" doesn't exist, this shouldn't even compile. so why do you have a runtime exception? make sure it's defined in class Game

I have playGame() in my BlackJack class. The whole point of it is (sry but just explaining it so I get my thoughts written down): the Game class is abstract, that abstract class has - abstract instructions, abstract welcome message, and abstract playGame. That means that every time i extend the Game class, i.e. my BlackJack class extends Game class, it will need to define these methods. So playGame has to be different with every game created.

it is defined in class Game as :

Code

public abstract void playGame();

then in my BlackJack class as:

Code

@Override
public void playGame() {

...code...
}
