Why does this CCSprite subclass code throw an exception?

Question

I have one problem in inheriting CCSprites in Java. Here is part of my code:

public class Block extends CCSprite
{
  static Block temp=null;
  static Block newBlock(tetrominoTypes blockType)
  {
    temp = (Block) Block.sprite(filename); // class cast exception here
    return temp;
  }
}

A class cast exception occurs at run time on the indicated line, how can I resolve it?

Answer 1

The documentation for Java's cast exception indicates that it is thrown when there is an attempt "to cast an object to a subclass of which it is not an instance."

In your case, whatever Block.sprite() returns is not something you can cast to a Block object. Since "sprite" appears to be a static member function of the Block class which you have not posted, there's not a whole lot more we are going to be able to do for you.
