I'm stuck on this

Can't figure it out!!

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 = true;

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

Hi there,

You're nearly there but you need to check if the obj is a String before casting it as one.

Use instanceof to create a boolean result for an if conditional statement. You want to see if obj is an instanceof a String.

If it is, cast obj to be a String and return that object. (Use one line for this!)

Make sense?

Steve.
