I am making a game and have have several LinkedLists with different objects that I want to .draw()

I would like them all to belong to a class that i call Drawable but even as I use: ~Class Monster Extends Drawable.
I still cant assign it to (Drawable). When I do it says expected (Drawable) but found Monster.

What am I doing wrong? :-/

Without seeing the code, it's hard to say, but extends should be lowercase.

After your answers I made some new objects with the Extends and it solved the problem, never knowing what the original issue was. Thanks

Mhm, sounds wired.

You use extends for classes, e.g.
1  
2  
3  
4  
5  
6  
7  
8  
9  
10  
11  
public class Animal {
  public void doIt() {
      System.out.println("Animal.doIt");
  }
}

public class Dog extends Animal {
  public void woof() {
    System.out.println("Dog.woof()");
  }
}

In general, each class should be in it's own file which is is called ClassName.java ( here Animal.java and Dog.java ).

Interfaces are used for describing general behaviour, for example a Plug-In architecture.
