charAt?

I know that I'm probably giving this question too late. I understand that charAt shows the location of a char in a String, but why exactly do we need to know that for our code?

Hi Dinu. The charAt(int i) method actually returns the letter in a String at a given index i. In the video and that Hangman exercise, we need to call charAt(0) because of the Scanner.

A Scanner in Java does not parse char. So we have to use a String, and then call charAt(0) on that String to get its first and only letter.

I hope this helps :)
