public static void create() { in = new Scanner(System.in); dateAndTime = getDateAndTime(); shopLocation = getShopLocationFromUser(); staffName = getFromUser("your first name"); staffName = capitalise(staffName);

//end of code

Note that in the create() method the class invokes a method written to make sure that the name entered by the user is capitalised appropriately: staffName = capitalise(staffName);. The capitalise(String) method takes a String parameter and returns a String. The method makes sure that the name entered by the user starts with a capital letter, with the rest of the name in lower case. Note that the capitalise(String) method uses String methods, such as substring() and toUpperCase() that you will find documented in the String API.

There is a TODO comment in the create() method that reads: //TODO client wants the item description in title case Different authorities have slightly different rules for title case, but title case means, in general, that every word is capitalised (meaning the word starts with a capital letter, but the rest of the word is in lower case), except for articles (a, an, the), prepositions (e.g. in, on) and conjunctions (e.g. and, or). In this case the client wants every word capitalised except for the words: a; an; and; the; of; with. This means that if the user were to type: REPLACE BATTTERY WITH A NEW BATTERY for the item description, what would be printed on the receipt would be: Replace Battery with a New Battery
