@Override error?!

...method does not override or implement a method from a supertype

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

  @Override
  public int compareTo(Object obj) {
    return 1; 
  }

  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;
  }
}

Soooo you have an @Override in your code. That shouldn't be there. BUT you also need to implement comparable in the class.

If you remove the override but keep the compareTo method. Then implement Comparable.

It will all work like magic. Let me know if that solves your issue.

I solved this like I wrote implementing comparable, no problem ;-)
