Can someone explain this lesson to me?

I understand that this video was about fixing the "no letter" bug, but why did Craig have to create a new method? Couldn't he have just modified the old applyGuess method to accept a string and throw an exception?

Hi Stephanie Fu. Craig create a new method because he wants to have two method with two responsibility, one of them works with strings and the other one works with characters. Best

Hi Stephanie, as per Sina. You are correct the applyGuess method could've just been modified to accept a string, but by using method overloading (two methods with the same name that accept different inputs) the application is able to accept both a string or a char which your solution wouldn't do.
