  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 result variable to be the correct string.
    if(obj instanceof String){

      BlogPost x = new BlogPost("1","2","3","4",new Date());
      obj = x.getTitle();
      return obj.toString();


    String result = "";
    return result;

This is just a general suggestion but I have run into some challenges where task 2 is failing but task 1 is being reported as the one with the error.

I would recommend to look at your current task in more detail before ensuring that task 1 is in fact at fault.

For example in an instance task 1 was only to declare a variable while step 2 was the use of a variable along with a method. Task 2 had a misspell on the method used but task 1 was listed as not longer passing. I knew for a fact that was not the case and was able to figure out this bug.
