Converting an integer to a string

[Varsteil]

I'm working on a program that lists coins as integers, then converts them to their values in dollars as a string, for example, 1 quarter and 1 dime (the inputs being 1 and 1) outputs as a string "$0.35"

code:

import java.util.Scanner; public class AddCoins {   static int penny, nickel, dime, quarter;   String total;     public static void main(String[] args) {     Scanner input = new Scanner(System.in);     System.out.println("Enter the amount of pennies you have");     penny = input.nextInt();     System.out.println("Enter the amount of nickels you have");     nickel = input.nextInt();     System.out.println("Enter the amount of dimes you have");     dime = input.nextInt();     System.out.println("Enter the amount of quarters you have");     quarter = input.nextInt();     total = "Total: $" + (penny * 0.01) + (nickel * 0.05) + (dime * 0.1) + (quarter + * 0.25); //Illegal start of type error   } }

You need to convert the sum integer to a string. Add them all up inside a pair of parentheses, and call toString() on the result of that.

code:

total = "Total: $" + ((penny * 0.01) + (nickel * 0.05) + (dime * 0.1) + (quarter + * 0.25)).toString();

I'm getting an "illegal start of expression" error, also, apparently, I'm only supposed to use 4 integers, so I don't think I can have another integer for the sum.

Oh, woops. total needs to be declared static. Also you have an extra '+' in that last line. Forget everything I said in my first post.

EDIT: Also, I recommend you multiply all your coin values by 100 when you add them (ie 1 penny = 1, not 0.01) and then divide the total by 100, or you'll get floating point errors (which basically means half your answers will be off by one penny).

The static methods Integer.toString(int), Double.toString(double), etc is used to apply the Boxed/Wrapper like methods that come with the Object version of the data type on the primitive data types.
Eg: Integer.toString(14);

Which might be what Insectoid was getting at if the wrapping ().toString() auto-boxes the value inside the brackets. However, you should learn to recognize when it is getting boxed into an Object and avoid such if at all possible.

I kinda just realized you might not have any idea about Objects and Autoboxing... Meh.
