Jade, hope this helps:

"Add a new method named getWords that returns the words from the body of the blog post. Since we don't need to worry about special characters, let's just use the regular expression pattern \s+ (or any one or more white space character) for the parameter to the split method. (Remember to escape the backslash in your Java code.)"

  public String[] getWords() {  //new method named getWords
    String words[] = mBody.split("\\s+");  //create array, split mBody on white space and puts words in array
    return words;  //return array
  }
