Hi, im confused. IN the video Craig makes another applyGuess method that is this time a boolean. But he already defined another one. Now i know that this one is unique because of the argument and type and all, but he only changes a little bit in the prompter class. So both methods interact with it because of the name ?

The only difference in the method signatures are the parameters they take, because the method needs to execute completely different code if it received a String or a char. Overloading allows the JVM to decide which version of the method to use based on what parameter the client is sending.
