I tried this and it didn't work actually...

  public static String getTitleFromObject(Object obj){
    String result = " ";
    if (obj instanceof String) {
     return (String) obj; 
    } else {
      return ((BlogPost) obj).getTitle(); 
    }
  }

Hi Jennifer,

Have a look through this post to see if that helps you out.

Let me know how you get on.

I just pasted your code in and it worked fine - what error are you getting and does clicking Preview give you any clues?

Have you added your code in the TypeCastChecker.java file?

Steve.

And have you set both HINT values back to false?
