title: Java variable isn't setting
body: <p>Alright so I'm trying to have the variables "totalTax" and "total" hold the price of the item, and they work fine when I call them within the method they are being set at, but when I call them from another class, it returns 0.</p>
  
  <pre><code>public class Input
  {
  private Scanner keybd;
  private String[] costArray;
  private String[] itemArray;
  private double totalTax;
  private double total;
  
  /**
   * Constructor for objects of class Scanner
   * 
   * @param anyAmountofItems the amount of items you are going to be buying
   */
  public Input(int anyAmountofItems)
  {
      keybd = new Scanner(System.in);
      costArray = new String[anyAmountofItems];
      itemArray = new String[anyAmountofItems];
      totalTax = 0.0;
      total = 0.0;
  }
  /**
   * Mutator method to set the item names and costs
   * 
   * @param anyValue the tax rate percentage (ex. 0.08 for 8%)
   */
  public void setArray(double anyValue){
      //System.out.println("Enter the sales tax percentage: ");
      //double salesTax = keybd.nextDouble();
      //for(int index=0; index &lt; itemArray.length; index++){ 
      //System.out.println("Enter the item name: ");
      //itemArray[index] = keybd.next();}
      double totalTax=0.0;
      double total=0.0;
      for(int indexc=0; indexc &lt; costArray.length; indexc++){
         System.out.println("Enter the item name: ");
         String anyName = keybd.next();
         itemArray[indexc] = anyName;
         System.out.println("Enter the item cost: ");
         double cost = Double.valueOf(keybd.next()).doubleValue();
         costArray[indexc] = " " + cost;
         totalTax = totalTax + (cost * anyValue);
         total = total + cost;
      }
      //for(int indexa=0; indexa &lt; itemArray.length; indexa++){
      //System.out.println(itemArray[indexa] + "-" + costArray[indexa]);}
      //System.out.println("Sales Receipt");
      //System.out.println("--------------");
      //for(int i=0;i&lt;costArray.length;i++){
      //    System.out.println(itemArray[i] + " - $" + costArray[i]);
      //}
      //returnCostArray();
      //System.out.println("Total tax: $" + totalTax);
      //System.out.println("Total cost pre-tax: $" + total);
      //System.out.println("Total cost including tax: $" + (total+totalTax));
      totalTax = totalTax;
      total = total;
  }
  public String returnArray(int anyElement){
      int index = anyElement - 1;
      return itemArray[index];
  }
  public double returnTotal(){
      return total;
  }
  public double returnTotalTax(){
      return totalTax;
  }
  public void returnCostArray(){
  for(int i=0;i&lt;costArray.length;i++){
      System.out.println(itemArray[i] + " - $" + costArray[i]);
      }
   }
   }
  </code></pre>
  
  <p>Then, I'm running this class which uses the Input class and it is returning 0, yet when I do the System.out.println in the same class that I already have, it works and returns the total.</p>
  
  <pre><code>public class TaxClass
  {
  private Input newList;
  /**
   * Constructor for objects of class Tax
   * 
   * @param anyAmount Enter the number of items
   */
  public TaxClass(int anyAmount)
  {
      newList = new Input(anyAmount);
  }
  /**
   * Mutator method to add items and their cost
   * 
   * 
   * @param anyTax Enter the sales tax percentage
   */
  public void addItems(double anyTax){
      double salesTax = anyTax;
      newList.setArray(salesTax);
      System.out.println("Sales Receipt");
      System.out.println("--------------");
      newList.returnCostArray();
      System.out.println("Total tax: $" + newList.returnTotalTax());
      System.out.println("Total cost pre-tax: $" + newList.returnTotal());
      System.out.println("Total cost including tax: $" +  (newList.returnTotal()+newList.returnTotalTax()));
  }
  //public String returnArray(){
      //newList.returnArray();
  //}
  }
  </code></pre>
  
  <p>EDIT: Local variable problem.  I'm trying to use the "return array(int AnyElement)" method in the first class, but when I try to compile it is telling me that: returnArray(int) in Input cannot be applied to ().  Any help?  Thanks!
  Thanks!</p>
