  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 Object getTitle(Object obj) {
    // Fix this result variable to be the correct string.

    BlogPost result = null;
    if(obj instanceof BlogPost)
      result = (BlogPost)obj;
    return result;

  public static String getTitleFromObject(Object obj) {
    // Fix this result variable to be the correct string.
    String result = "";
    if(obj instanceof String)
      result = (String)obj;
    return result;

its not working exercise question.

Here is the questions for Task 1 and Task 2:

Challenge Task 1 of 2

The method getTitleFromObject will be called and passed a String and/or a com.example.BlogPost. For this first task, return the object obj type casted as a String if it is in fact a String.

I've included BlogPost.java for your reference only.

Challenge Task 2 of 2

Now make sure that if a com.example.BlogPost is passed in for obj that you then cast it to a BlogPost. Return the results of the getTitle method on the newly type-casted BlogPost instance.

I also copied my code that passed the challenge if you need help with that as well.
