My program is supposed to ask someone to enter a serial number and the price of an object.
Here is the class driver
import java.io.*;
import java.util.Scanner;
public class InventoryDriver {
    public static void main(String[] args)throws IOException {
        Inventory storeItem = new Inventory(" ", 1);
        PrintWriter storeFile = new PrintWriter("StoreInventory.txt");
        Scanner scan = new Scanner(System.in);
        boolean running = true;
        String itemNum = " ";
        double originalPrice = 1;
        while (running) {
            System.out.println("Enter the item number or enter 0 when you are done.");
            itemNum = scan.nextLine();
            storeItem.setItemNum(itemNum);
            storeFile.println(itemNum);
            if(itemNum.equals("0")) break;
            System.out.println("Enter the original price or enter 0 when you are done.");
            originalPrice = scan.nextDouble();
            storeItem.setOriginalPrice(originalPrice);
            storeFile.println(originalPrice);
            if(originalPrice == 0) break;
        }
        //create a scanner variable named myFile
        Scanner myFile = new Scanner(new File("StoreInventory.txt"));
        //Read my data from my file into the variablles
        //itemNum = myFile.nextLine();
        //originalPrice = myFile.nextDouble();
        printSaleData(myFile, storeItem);
        //Close the file
        myFile.close();
        storeFile.close();
    }
}
After working perfectly the first time with this output
    Enter the item number or enter 0 when you are done.
    input
    Enter the original price or enter 0 when you are done.
    input
But when the loop goes back, it prints this
    Enter the item number or enter 0 when you are done.
    input
    Enter the original price or enter 0 when you are done.
    input
    Enter the item number or enter 0 when you are done.
    Enter the original price or enter 0 when you are done.
    input
What about my code changes the loop after the first go?
P.S. Even after I break the loop the whole program stops, and won't call the "printSaleData" sub-module to the main module.
