String instead of char?

The video has this line of code;

String guessInput = scanner.nextLine();
char guess = guessInput.charAt(0);
return game.applyGuess(guess);

Would this not be better? if not why?

char guessInput = scanner.nextLine();
return game.applyGuess(guessInput);

this method scanner.nextLine() returns a String, hence, this value can't be assigned to guessInput if guessInput is a char. This has to do with the fact that Java is a strongly typed language, if a variable is assigned a new value, that new value needs to be of the same type w/ the variable, otherwise it's syntax error.
