override

Question

There's a compiler error that says there's nothing to override, but I'm overriding the compareTo method.

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+");
  }

  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) {
    return 1; 
  }
}

Your code is fine, but you are getting this error because you have not implemented the Comparable interface. If you add implements Comparable to the class it will work.
