Question
Hi i need help to expand my candy machine java project I already did the best selling and worst selling and half of the timestats however the timestats doesnt work good and i also need to have the totalsales of all products and searchtransaction here is the description of the assignment that i need to complete i need help with timeStats totalSales and searchTransaction the other answer was wrong and it did not function correctly how can I test the three methods.
public static void adminMenu()
{
System.out.println(" *** Admin Menu ***");
System.out.println("Selections ");
System.out.println("1 Print all transactions");
System.out.println("2 Show Best Selling Item");
System.out.println("3 Show Worst Selling Item");
System.out.println("4 Show statistics by Time");
System.out.println("5 Show total $ amount of sales");
System.out.println("6 Search Sales");
System.out.println("9 to exit");
}//end showSelection
Together in class we made option 1 functional
Create methods that will make the other options functional:
bestSelling(...) -- This should show the best selling item and the number sold.
worstSelling(...) -- This should show the WORST selling item and the number sold.
timeStats(...) -- Give the user the option to search by full time (H:M:S) or individually Hour, Minute or Second.
Prompt the user by allowing he/she to choose a range (i.e. "starting from"..."Ending at")
then print any transactions that have occur during that range.
totalSales(...) -- Just simply let this one show the grand total ($) of all sales (No breakdown necessary)
searchTransactions(...) -- Allow the user to search for any transactions by name (allow wildcards --- see below) or price range.
NOTE: Wildcards means the user could just type in 1 or a few letters of the named item without having to type in the full name and still see results. For example if the user typed in just the letter "c" in their search, then it should show results for anything starting with "c" (i.e. "candy"..."chips") For this you will have to investigate the rich selection of methods that the "String" class provides.
and here is the code
