I was able to revise my code. now have it working. thank you for your assistance on this posting.

Sorry I forgot .. I now have (CODE) before and after each of the 4 classes.

Again any assiatance would be greatly appreciated,

Hi ..
I will try to explain what I am trying to do.... but before I start... I will say I was able to successfully return the concatenated String variable back to the calling class. I verified this by entering a print statement after the call to the get method in ComputerPart.

What I am trying to do is generate test data. I need to create an order (this works) and create a product that is associated with the order. You can have multi. orders with multi products associated with the individual order #.

Here is the error message I am getting.

OrderGenerator.java:37: addProduct(net.allenwhite.order.Product) in net.allenwhi
te.order.GenericOrder cannot be applied to (java.lang.String)
genericorder.addProduct(product);
                    ^

thank you any assistance would be appreciated. I know something is not compatible....

here is a sample of my code...
the calling class can be referred to as OrderGenerator
the getmethod is located in ComputerPart class
also included is code for Product.java & GenericOrder.java (these are referenced in the OrderGenerator class. )

1 of 4

public class OrderGenerator {

private Random rand = new Random();

public GenericOrder generateOrder() { //create an order

System.out.println("[ORDER GENERATOR] starting ...");
GenericOrder genericorder = null; 

int orderType = rand.nextInt(1);
switch (orderType) { 
case 0: genericorder = new ComputerOrder();
break;
}

int numberOfProducts = rand.nextInt(6);
numberOfProducts++; // We always want at least …

I meant to include in previous entry the following error message:

OrderGenerator.java:37: addProduct(net.allenwhite.order.Product) in net.allenwhi
te.order.GenericOrder cannot be applied to (java.lang.String)
genericorder.addProduct(product);
^

      int numberOfProducts = rand.nextInt(6);
      numberOfProducts++; // We always want at least one egg.
      for (int counter=0; counter<numberOfProducts; counter++) {
        // Determine the type of egg to add.
        String product = null;
        ComputerPart compart = new ComputerPart();
        int productType = rand.nextInt(1);
        switch (productType) {
            case 0:
                product = compart.getComputerPart();
                System.out.println("[back in calling class - Class A] " + product);
        break;
         }
        // Add the product to order
           genericorder.addProduct(product);                                         
    }
   return …

I tried changing the getmethod to return an Integer instead of ClassB and revised the returm line (See bold code below).

  public [B]Integer [/B] getComputerPart() {
    String floatToString=Float.toString(instPrice);
    String conString = instDesc+instMfg+floatToString;
    [B]return Integer.parseInt(conString);[/B]
   }

the calling class (Class A) has prod defined as Product prod = null;
where Product is a class with subclasses.

        Product prod = null;
        ComputerPart compart = new ComputerPart();
                   prod = compart.getComputerPart();
                   System.out.println("[ordergenerator back ] " + prod);

The following is the new error I am receiving. I am thinking that the type returning from the getComputerPart() is not being accepted by the prod variable. it may help if I understood what
type is "Product prod = null".

ERROR 
OrderGenerator.java:33: incompatible types
found   : java.lang.Integer
required: net.lois.order.Product
                   prod = compart.getComputerPart();

Hi,

I am new to the java world.

I am getting the following error.

ClassB.java:62: incompatible types
found   : int
required: order.ClassB
        return Integer.parseInt(conString);

This what I am trying to do..

I have two classes. Class A and Class B. Class A calls a method located in Class B (refer to code below).

Class A

        Product prod = null;
       ComputerPart compart = new ComputerPart(); 
       prod = compart.getComputerPart();

Class B

I have three local variables (xdesc,xmfg,xprice) and I have three instance variables defined (instDesc,instMfg,instPrice). instDesc and instMfg are String variables and instPrice is a float variable. the local variables are assigned to the instance variables.

Then I converted the float variable instPrice to String and concentated call three variable into a Sting variable called conString. then try to return conString back the variable called prod in the calling class (Class A).

   public Class B getComputerPart() {
     .
     .
     .

    instDesc = xdesc;
    instMfg  = xmfg;
    instPrice = xprice;

    String floatToString=Float.toString(instPrice);
    String conString = instDesc+instMfg+floatToString;
    return Integer.parseInt(conString);
} 

any assistance on what I can do to convert the string variable conString to a type that is accepted by the prod variable in Class A. in addition, I believe it may have something to do with the following line of code in ClassA "Product prod = null". prod will not accept conString.
