Unable to access getter method in an object class I made

[EnSlavingBlair]

Hello,

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

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

And my CreateObject class looks like this:

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();
	}
	
	/**********
	 * getKey *
	 **********/
	
	public String getKey()
	{
		return key;
	}
	
	/************
	 * getBrand *
	 ************/
	
	public String getBrand()
	{
		return brand;
	}
	
	/************
	 * getModel *
	 ************/
	
	public String getModel()
	{
		return model;
	}
	
	/*************
	 * getWeight *
	 *************/
	
	public int getWeight()
	{
		//System.out.println("getWeight weight:"+weight);
		return weight;
	}
	
	/*************
	 * setWeight *
	 *************/
	
	public void setWeight(String inWeight)
	{
		if (weight<0) 
		{
			throw new IllegalArgumentException("Weight must be positive");
		}
		//System.out.println("setWeight weight:"+weight);
	}
	
	/************
	 * getPrice *
	 ************/
	
	public double getPrice()
	{
		//System.out.println("getPrice price:"+price);
		return price;
	}
	
	/************
	 * setPrice *
	 ************/
	
	public void setPrice(String inPrice)
	{
		if (price<0) 
		{
			throw new IllegalArgumentException("Price must be positive");
		}
		//System.out.println("setPrice price:"+price);
	}
	
	/*************
	 * To String *
	 *************/
	public String toString()
	{
		String fieldString;
		fieldString=new String("\nKey: "+key+"\nBrand: "+brand+"\nModel: "+model+"\nWeight: "+weight+"kg\nPrice: $"+price);
		return fieldString;
	}
}

The error I'm getting is:

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?

[EnSlavingBlair]

Do you mean something like this?:

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..

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

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

Yes that is what I mean. Glad you understand it. :)
