How can I turn an object into a string?

In this problem, the method getTitleFromObject gets called and passed an object. I'm supposed to take that object and somehow convert it into a string for the method to be returned. Any ideas as to how I could do this?

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;
    }
}
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.
    obj.toString();
    String result = "";

    return result;
  }
}

hi Kaytlynn Ransom , remember to use the hints to solve this challenge

/*************** 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.
     String result = "";
    if (obj instanceof String) {
      return (String) obj;
    }
    return result;
  }
}
