The expression needs to be extremely precise. Make sure you are matching the split expression EXACTLY as it appears in the question. It should look something like this

public String[] getWords() {
   return getBody().split("xxx"); \\xxx should be replaced with the correct expression
}

I hope this helps! Happy coding!
