Unable to access getter method in an object class I made

Hello,

I cannot seem to be able to use a .getKey in my code. I am trying to access it as below:

Code:

---

public static void MakeChoiceAgain(int choice, CreateObject[] array)
{
    String key=array.getKey();
    ...
}

---

And my CreateObject class looks like this:

Code:

---

import java.util.StringTokenizer;

public class CreateObject
{
        /*****************
        * member fields *
        *****************/
       
        private String key, brand, model, inKey, inBrand, inModel, inWeight, inPrice;
        private int weight;
        private double price;
        private String[] tokens;
       
        private String csvRow;
        //csvRow=ConsoleInput.readString("Enter something:");
       
        /*************************
        * Alternate Constructor *
        *************************/
       
        //public CreateObject(String inKey, String inBrand, String inModel, String inWeight, String inPrice)
        public CreateObject(String inCsvRow)
        {
               
                tokens=inCsvRow.split(",");
                inKey=tokens[0];
                inBrand=tokens[1];
                inModel=tokens[2];
                inWeight=tokens[3];
                inPrice=tokens[4];
               
                key=inKey;
                brand=inBrand;
                model=inModel;
                weight = Integer.parseInt(inWeight);
                setWeight(inWeight);
                price = Double.parseDouble(inPrice);
                setPrice(inPrice);
        }
       
        /********************
        * Copy Constructor *
        ********************/
       
        public CreateObject(CreateObject inCreateObject)
        {
                key=inCreateObject.getKey();
                brand=inCreateObject.getBrand();
                model=inCreateObject.getModel();
                weight=inCreateObject.getWeight();
                price=inCreateObject.getPrice();
        }
       
        /**********

        /*************

                return weight;
        }

}

The error I'm getting is:

Quote:

---

cannot find symbol
symbol : method getKey()
location: class CreateObject[]
String key=array.getKey();

Can anyone please tell me what I'm doing wrong?

Cheers

You have an array of CreateObject so you need to tell the index of CreateObject that you are trying to access.

I don't really understand what you mean by that?

Do you mean something like this?:

Code:

---

public static void MakeChoiceAgain(int choice, CreateObject[] array)
        {
                for (int i=0; i<array.length; i++)
                {
                String key=array[i].getKey();
                ...
                }
        }

---

Because that stopped giving me the previous error..

It's like this: a house has a doorbell but a block of houses doesn't have a doorbell. It's the same with your code: your class object has a getKey() method but an array of your objects doesn't have that method. As a matter of fact, an array doesn't have methods at all.

kind regards,

Jos
