Your code is missing a period after the array index. i.e., cameras[i].getCameraName(); // note the period to dereference the variable.

The compiler is not very forgiving, and everything has to be just so for it to be happy.

Best to see your current code, so we can see everything in context.

Again, it would be best if you posted your current code so that we can see what it's doing.

Is this code all in one file? If so, what's the name of the file? And, do you have code for the Cameras class?

[MikeJ39]

camera the first class and Supplier is the second class and inventorypart4 is the last one

[Fubarable]

camera the first class and Supplier is the second class and inventorypart4 is the last one

I'm sorry, maybe my questions above weren't clear. I'm trying to fully understand your error, and for me it will take a little more information, and so I have three questions:

1. Is the code that you've posted in post number 8 (labeled #8 in the upper left corner of the post) all in one file, or do you have the two classes in separate java files?
2. If they're in the same file, what is the exact name of the file?
3. Can you post the code from the Camera or Cameras class as I don't see that this has been done yet (unless I'm missing it)?

If these questions don't make sense, please feel free to ask for clarification.

[MikeJ39]

In Label#8 there is Supplier Class and InventoryPart4 Class and here the Camera Class:

class Camera{

public static void main(String[] args){
}

private int itemNumber;

private String productName;

private int unitsInStock;

private double price;

 

public Camera() {

}



public Cameras(int itemNumber, String productName, int unitsInStock,

double price) {

this.itemNumber = itemNumber;

this.productName = productName;

this.unitsInStock = unitsInStock;

this.price = price;

}
         

public double calculateInventory() {

return this.unitsInStock * this.price;

}



public int getItemNumber() {

return itemNumber;

}

public String getCameraName() {

return CameraName;

}

public int getUnitsInStock() {

return unitsInStock;

}

public double getPrice() {

return price;

}


public void setItemNumber(int itemNumber) {

this.itemNumber = itemNumber;

}

public void setName(String cameraName) {

this.cameraName = cameraName;

}

 


public void setUnitsInStock(int unitsInStock) {

this.unitsInStock = unitsInStock;

}


public void setPrice(double price) {

this.price = price;
}
                


}

[Fubarable]

What about my questions #1 and #2 above?

[MikeJ39]

ok yes there is 2 files there and i need to link them to just one so i can get the InventoryPart4 to work i hope that anwsers your question

[Fubarable]

There should be at least 3 files here, one for each Java class: Supplier.java, InventoryPart4.java and Camera.java (or Cameras.java -- it's not clear).

Then you need to try to just compile the most base class present, which I guess is Camera and show us just the errors from this class. Already I see some contradiction as the class name appears to be Camera but your constructor is Cameras, and these two names must match exactly. Again, the compiler is very strict, and so we must be just as strict about our code if has any hope of succeeding. Only after you have the Camera class compiling correctly can you begin to consider working on the next class, Supplier, and the same for InventoryPart4.

[MikeJ39]

its Cameras.java

[Fubarable]

its Cameras.java

OK, but the code you posted has this:

class Camera{
 
  public static void main(String[] args){
  }
 
  private int itemNumber;
  private String productName;
  private int unitsInStock;
  private double price;
 
  public Camera() {
 
  }

  //....

So the class name and one constructor name is Camera and this will cause errors as the file name, class name, and constructor names must all agree exactly. You will want to change them to Cameras, then recompile your code, look for any errors that come from the Cameras class and try to fix them. If you still get stuck, then post the Cameras class again and the latest error messages.
