Java combining arrays

What I'm trying to do is ask the user for a list of items, and create two arrays - one for the itemName and one for the itemPrice. My program right now deals only with the itemPrice and there's no indication of how I can combine two arrays in one to output a list of both arrays combined, like this:

Bread - 1.20
Milk - 2.00

Here is what I have so far, two arrays, but the name array really isn't included in anything. Thanks!

Code:

---

public class TaxClass
    {
    private Input newList;
    /**
    * Constructor for objects of class Tax
    * Enter the number of items
    */
    public TaxClass(int anyAmount)
    {
        newList = new Input(anyAmount);
    }
    /**
    * Mutator method to add items and their cost
    * Enter the sales tax percentage
    */
    public void addItems(double anyTax){
        double salesTax = anyTax;
        newList.setArray(salesTax);
    }
    }

    public class Input
    {
    private Scanner keybd;
    private String[] costArray;
    private String[] itemArray;

    /**
    * Constructor for objects of class Scanner
    */
    public Input(int anyAmountofItems)
    {
        keybd = new Scanner(System.in);
        costArray = new String[anyAmountofItems];
        itemArray = new String[anyAmountofItems];
    }
    /**
    * Mutator method to set the item names and costs
    */
    public void setArray(double anyValue){
        for(int index=0; index < itemArray.length; index++){
        System.out.println("Enter the item name: ");
        itemArray[index] = keybd.next();}
        for(int indexa=0; indexa < itemArray.length; indexa++){
        System.out.println(itemArray[indexa]);
        double totalTax=0.0;
        double total=0.0;
        for(int indexc=0; indexc < costArray.length; indexc++){
          System.out.println("Enter the item cost: ");
          double cost = Double.valueOf(keybd.next()).doubleValue();
          totalTax = totalTax + (cost * anyValue);
          total = total + cost;
        }
        System.out.println("Total tax: " + totalTax);
        System.out.println("Total cost pre-tax: " + total);
        System.out.println("Total cost including tax: " + (total+totalTax));
    }
    }

You don't need to combine the arrays to get the output you desire. Just access each array and concatenate them to a single line:

Code:

---

...
System.out.println(itemArray[index] + " - " + costArray[index]);
...

---

When I do that it comes up like this:

Milk-null
Bread-null
Cookies-null
Chocolate-null
Cereal-null
Total tax: 0.52
Total cost pre-tax: 6.5
Total cost including tax: 7.02

You never store the cost in your costArray[]. Look in your for loop, you retrieve the item cost, but you never actually store it in the costArray.

so how do I fix it?

You set the costArray the same way you set your itemArray. Does the cost variable hold the value that you need? If so, you would set it like this:

Code:

---

...
double cost = Double.valueOf(keybd.next()).doubleValue();
costArray[indexc] = cost;
...
