Question

ok my getBreadInfo code is

public static String[] getBreadInfo()  
{   
    ArrayList<String> breadsList = new ArrayList<>();

        try (BufferedReader in =
                new BufferedReader(
                new FileReader("bread.txt")))
        {
            String line = in.readLine();
            while (line != null)
            {
                String[] elems = line.split("~");
                breadsList.add(elems[0]+ " $" + elems[1]);
                line = in.readLine();
            }

        }
        catch(IOException e)
        {
            System.out.println(e);
            return null;
        }
    String[] breadInfo = breadsList.toArray(new String[]{});
    return breadInfo;
}

and in my main app to display this array is as

public static void displayBreadMenu()  
{  
    System.out.println("=== Select Sandwich Bread ===");

   String[] breadInfo = SandwichDB.getBreadInfo();
   for (String breads : breadInfo)
   {
       System.out.println(breads);
   }
}

it prints on console as

=== Select Sandwich Bread ===
White bread 1.50
Wheat bread 1.80
French bread 2.00
Organic bread 2.30

How would I add an integer value to associate with each array? like
1 White bread
2 Wheat bread
3 French bread
4 Organic bread

i’m told my getBread() is similar to getBreadInfo, except it only contains the
bread name, and return another array bread[] for SandwichApp to figure
out which bread the user selected because user type in a number
associate with the bread (index+1), rather than bread name.

Do i write the integer value in my getbread() or is the getBread just to check which bread the user selected?

Answer 1

how about having an counter and appending it while adding to the list.

int count=1;
 while (line != null)
            {
                String[] elems = line.split("~");
                breadsList.add(count+" " +elems[0]+ " $" + elems[1]);
                line = in.readLine();
                 count++;
            }
