$//$ Step $2$b: For each token $($word$)$ that you extract from

$//$ the input sentences, build a StringBuilder object. We

$//$ learned in lecture that the StringBuilder Class has

$//$ many useful methods used to manipulate a String.

$//$ Perform a web search for "Java $8$ API", and access the

$//$ oracle webpage. Click on the StringBuilder class

$//$ name in the navigation box on the left of the

$//$ screen, and look for a method that will reverse the

$//$ String field in the StringBuilder object that you've

$//$ created.
