Hello,

It looks like there is a missing a curly brace at the end of TypeCastChecker.java:

import com.example.BlogPost;

public class TypeCastChecker {
  /***************
  I have provided 2 hints for this challenge.
  Change `false` to `true` in one line below, then click the "Check work" button to see the hint.
  NOTE: You must set all the hints to false to complete the exercise.
  ****************/
  public static boolean HINT_1_ENABLED = false;
  public static boolean HINT_2_ENABLED = false;

  public static String getTitleFromObject(Object obj) {
    // Fix this return statement to be the correct string.

    String title = "bad type";
      if(obj instanceof BlogPost) {
          BlogPost post = (BlogPost) obj;
         title = post.getTitle();

          }
      if(obj instanceof String) {
          title = (String) obj;

          }

      return title;

  }
} //add a curly brace here

Notice the addition of a curly brace at the bottom. Everything else looks good!

Hope this helps!
