When I printout the array contents, it prints null rather than the expected entered data. Will someone please tell me what I am doing wrong? Thanks. My code follows;
import java.util.Scanner;
public class Inventory {
public static void main(String[] args)
{
Scanner input = new Scanner( System.in );
boolean isValid = true;//**
String productName;// = "DVD"//++
int productNumber;//++
int onHand;//++
double price;//++
//double totalInventory;//++
//int count;
double totInventory;//[] = new double[3];//++
//totalInventory = 0;
int count = 0;
while (isValid)
{
System.out.println ("Enter Product Name. Enter exit to quit program");
productName = input.next();
if (!productName.equalsIgnoreCase ("exit"))//++
{
System.out.println ("Enter Item Number: ");
productNumber = input.nextInt();
System.out.println ("Enter number of items in stock: ");
onHand = input.nextInt();
System.out.println ("Enter item price: ");
price = input.nextDouble();
//compute student grade
totInventory = (onHand * price);
//create a new class and pass the values to the method
Product.getData(productName, productNumber, onHand, price, totInventory, count);//+++
count++; //increment the counter to use as the array position in second class//+++
}
else
{
isValid = false;//**
System.out.print ("Item Name" + "\t");
System.out.print ("Item Number" + "\t");
System.out.print ("Items on Hand" + "\t");
System.out.print ("Item Price" + "\t");
System.out.print ("Items Value" + "\t");
System.out.print ("Total Value" + "\n");
//Product.printAll(count);
Product.printArray(count);
//}
//Product.modifyArray(count);
System.out.println ("Thank you, come again.");
break;
}
}
}
