Whats wrong with getBody?

I am using the following for the getWords method:

public String [] getWords(){ return getBody.toLowerCase().split("\s+"); }

But I keep getting the following error:

./com/example/BlogPost.java:41: error: cannot find symbol return getBody.toLowerCase().split("\s+"); ^ symbol: variable getBody location: class BlogPost 1 error

Any suggestions??

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 getBody.toLowerCase().split("\\s+");
  }
  ./com/example/BlogPost.java:41: error: cannot find symbol
    return getBody.toLowerCase().split("\\s+");
           ^
  symbol:   variable getBody
  location: class BlogPost
1 error
}

I think you want to use mBody not getBody.

OK, you can use getBody but it is a method so you need the brackets for it before you chain .split() against it.

So you have two options:

public String[] getWords(){
  return getBody().split("\\s+");
}

// OR

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

I hope that makes sense.
