Error: Task 1 is no longer passing but after going back to Task 1 it's actually passing wtf?!

Question

And in that case I don't have any preview to the console where I would expect to see compilation errors.

Could anyone take a look at my code and tell me what did I do wrong?

com/example/BlogPost.java

package com.example;

import java.util.Date;

public class BlogPost implements Comparable {
  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;
  }

  @Override
  public int compareTo(Object obj){
    if(((BlogPost)obj).equals(obj)){
      return 0;
    }
    return 1;
  }
}

Hi there... You need to cast the obj first.

 @Override
  public int compareTo(Object obj){
    if(((BlogPost)obj).equals(obj)){//<-- this is not how you cast an Object and sure is not how equals work
      return 0;
    }
    return 1;
  }

This is the revision version of your code:

@Override
  public int compareTo(Object obj) {
    BlogPost blogPost = (BlogPost) obj;//<-- this is casting
    if(equals(obj)){//<-- this is how to use equals
      return 0;
    }
    return 1;
  }

please try it and I hope it will work. I hope this helps a little.
