char conversion to uppercase

[PsychoNaut]

Hello all I am new to java and am having a problem with a particular part of my code :

//Constructor

public CarRental (String initialCustomerName, String initialMake, char initialRatingKey) {


customerName=initialCustomerName;
make=initialMake;
ratingKey=initialRatingKey;


switch(initialRatingKey)

{

case 's': initialRatingKey=initialRatingKey.toUpperCase();
case 'c': initialRatingKey=initialRatingKey.toUpperCase();
case 'u': initialRatingKey=initialRatingKey.toUpperCase();
case 't': initialRatingKey=initialRatingKey.toUpperCase();
case 'b': initialRatingKey=initialRatingKey.toUpperCase();


}


}

What I am trying to do is to convert a char entry to uppercase if a lowercase letter is typed in. Apparently initialRatingKey.toUpperCase() is not legal. I would appreciate any help thanks!

Why do the to upper case in the Switch? Why not just call toUpperCase on all char input. If it already is upper case then no changes are made. Oh and toUpperCase is a static method of the Character class meaning it should be called on the Character class itself and it must take a parameter. Please look up the Character API for more details.
