??? When an object `equals` another, the compareTo method should return 0. Current method returned 1. ??? Current error

This exercise is very confusing and I'm getting now answers and can't move on.

Here's my source code:

package com.example;

import java.util.Date;

public class BlogPost implements Comparable //just make the class implement Comparable interface, { 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[] getWords() { return mBody.split("\s+"); }

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; }

//Let's allow our BlogPost to be sorted. In this first step, //and produce a compareTo method that accepts an object as a parameter. public int compareTo(Object obj) { //In this step, cast the Object passed to the compareTo method to a com.example.BlogPost. //Check for equality first, if they are equal return 0. BlogPost post = null;

if(post == obj){
  post = (BlogPost) obj;
}
return 1;//Leave the default return of 1 in place for this step.

} //Have it always return 1 for this first step, we'll do more in the next step. }

As you can see by the comments in the code, I'm following the instructions to the T and getting no where. I can't have two separate returns yet neither a return of 1 or 0 will work for this exercise.

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[] getWords() {
    return mBody.split("\\s+");
  }

  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;
  }
}
