TypeCasting

Bummer! I expected the String value I passed in to be returned and it wasn't. Received '' I need help!!! What is really wrong here?

com/example/BlogPost.java
package com.example;

import java.util.Date;

public class BlogPost {
    private String mAuthor;
    private String mTitle;
    private String mBody;
    private String mCategory;
    private Date mCreationDate;

    public BlogPost(String author, String title, String body, String category, Date creationDate) {
      mAuthor = author;
      mTitle = title;
      mBody = body;
      mCategory = category;
      mCreationDate = creationDate;
    }

    public String getAuthor() {
      return mAuthor;
    }

    public String getTitle() {
      return mTitle;
    }

    public String getBody() {
      return mBody;
    }

    public String getCategory() {
      return mCategory;
    }

    public Date getCreationDate() {
      return mCreationDate;
    }
  public static String getTitleFromObject(Object obj) {
    String result = "";
    if (obj instanceof String) {
      result = (String) obj;
    } else if (obj instanceof BlogPost) {
      result = ((BlogPost) obj).getTitle();
    }
     return result;
    }
}
TypeCastChecker.java
import com.example.BlogPost;

public class TypeCastChecker {
  /***************

  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.
    String result = "";
    return result;
  }
}

You wrote the getTitleFromObject method in the wrong file. You wrote it in BlogPost but it is already provided in the other file TypeCastChecker. Try moving your method there.
