Hi Griffin

You just missing an escaping character to your regular expression. It is should be "\s+" rather than "\s +". This is how the code supposed to be:

public String[] getWords() {
  //return mBody.split("\s +");<--the regex writing is wrong 
//because the Java needs escaping character ('\') to ensure it reads \s+ without it Java will only read s+ 
//oh also it is \s+ (meaning one or more white spaces as splitter) not \s +
    return mBody.split("\\s+");//<--this is how you need to write your regular expression
  }

I hope this can help a little.
