title: The method *****is undefined for the type***** in Java
body: <p>I'm trying to call a method from an abstract class Sprite in another package, but I got "The method getSymbol() is undefined for the type Sprite"</p>
  
  <p>Here's the code.</p>
  
  <p>And here is the code from another package sprites</p>
  
  <p>I guess the problem is that the method from an abstract class cannot be instantiated.</p>
  
  <p>But I don't know how to fix it.</p>
