in the prompter class what is the use of the below code in PromptForGuess method: char guess = guessInput.charAt(0); As I got confused on that line because why are we asking to get the first letter of the word.

if the confusion is related to the use of 0 in this like
char guess = guessInput.charAt(0);
Then this is because java is zero(0) based index language ... same a s C and C#,
therefore, if I have an array of 3 elements ,,, le cally myArry[3]. the the array contents are:
myArry[0]. myArry[1], myArry[2]
you can think of a string a an arry of Char. Therefore is a have a string "this is my string" and I wan to get the first char in this string, then I would
char myChar= "this is my string".charAt(0);
myChar will hold the letter 't'
Hope this helps clarifies
Thanks
