Expected 11 words, but received 12

Created String[] getWords() to return the words from the body of the blog post. When I check my code I get the error "Bummer! Expected 11 words, but received 12". Not sure what I'm doing wrong. Thanks!

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;
  }

  public String[] getWords() {
    return mBody.toLowerCase().split(" ");
  }

}

In the instructions at the top of the problem, it's asking you to use the regular expression "\s+ " to split the strings on. If you use that instead of " ", it should fix the problem.

Hey, thanks for that. Also, in case you want more info on that, Craig glosses over it, but here's a cheat sheet to make any kind of expression you want: http://regexlib.com/CheatSheet.aspx?AspxAutoDetectCookieSupport=1

Thanks! "\s+" did the trick.

I tried \s+ previously, but I had put a whitespace after the plus: ("\s+ ") and I got the same error.

Thanks for your help.

Glad it worked for you! Hey, if that helped you out, would you mind making that best answer so I can get the points for it? I trying to work my way through this program. Thanks!
