Having an issue with this

[baap30]

i have a program for an Inventory project using arrays no errors on this but the output is 3 lines of this

//Product@1a8c4e7
Product@1a8c4e7
Product@1a8c4e7

this is my code
code

// class inventory1{
	
	


private String name;//product name 
private int number;//item number 
private int units;//units available 
private double price;//price per unit 


public void Inventory1 () //Default constructor 
{ 

}//End default constructor Product 


//Initialization Constructor 
public void Inventory1 ( String nameIn, int numberIn, int unitsIn, double priceIn) 
{ 

setName (nameIn); 
setNumber (numberIn); 
setUnits (unitsIn); 
setPrice (priceIn); 
//setValue (valueIn); 

} //End initialization constructor Product 


//Declare Set/Get Methods 
public void setName( String nameInput ) 
{ 

name = nameInput; 


} //End method setName

        { 
        units = unitsInput; 
        } 
        public void setPrice ( double priceInput ) 
        { 
        price = priceInput; 
        } //End method setPrice

} //End method getUnits 

        public double getPrice () 
        { 
        return ( price ); 
} //End method getPrice 

        public double InventoryValue() 
{ 
return ( units * price ); 

} //End method InventoryValue 

//toString()Method 

//Returns a formatted String for output purposes

{ 
         String formatString    =  "Identification Number "+getNumber()+"\n"; 
         formatString                    += " Product Name               "+getName()+"\n";

          return formatString;

Moderator Edit: Code tags added

[Fubarable]

I've added code tags to your post to try to help show the code's formatting, but unfortunately your formatting is poor, and this makes it hard for others (namely us) to read and analyze your code. If you desire our help, it would be in your best interest to reformat your code and then edit your first post and repost the code.


From the little I can understand, you seem to have a class called inventory1 that has bad constructors (constructors should have no return type, not even void), but at least has a toString() method, but I don't see where you ever use inventory1 objects. You do use Product objects and even try to call toString() on these objects but haven't given this class a decent toString() method (that's the cause of your error).

If you fix up your code, maybe we can tell you more.

Best of luck and welcome to the forum.

here is the addition of the missing code but the results are the same

code:
class inventory1
{




private String name;//product name
private int number;//item number
private int units;//units available
private double price;//price per unit


public void Inventory1 (){ //Default constructor


}//End default constructor Product


//Initialization Constructor
public void Inventory1 ( String nameIn, int numberIn, int unitsIn, double priceIn)
{

setName (nameIn);
setNumber (numberIn);
setUnits (unitsIn);
setPrice (priceIn);
//setValue (valueIn);

} //End initialization constructor Product


//Declare Set/Get Methods
public void setName( String nameInput )
{

name = nameInput;


} //End method setName



public void setNumber ( int numberInput )
{

} //End method setNumber


public void setUnits ( int unitsInput )
{
units = unitsInput;
}
public void setPrice ( double priceInput )
{
price = priceInput;
} //End method setPrice

public String getName ()
{
return ( name);
} //End method getName

public double getNumber ()
{
return ( number );
} //End method getNumber

public double getUnits ()
{
return ( units );
} //End method getUnits

public double getPrice ()
{
return ( price );
} //End method getPrice

public double InventoryValue()
{
return ( units * price );

} //End method InventoryValue

//toString()Method

//Returns a formatted String for output purposes

public String name()
{
String formatString = "Identification Number "+getNumber()+"\n";
formatString += " Product Name "+getName()+"\n";
formatString += " Units In Stock "+getUnits()+"\n";
formatString += " Unit Price "+getPrice()+"\n";
formatString += "Inventory Value "+InventoryValue()+"\n";

return formatString;

}//End name()


//End Inventory1
import java.util.Scanner;

public class Inventory

{
//main methods begins execution of application
public static void main (String args [] )

{

Scanner input = new Scanner (System.in );
Product p = new Product ( );


System.out.printf (p.toString () );
}
}//End InventoryApplication

desperate to solve this

[Fubarable]

Hey, I added code tags the last time, if you read the link in my signature, you can learn how to edit your post above and add them yourself. All of us here will thank you for doing this because it will make reading your code that much easier.

Best of luck!

[Fubarable]

Also you've not fixed any of the problems that I indicated in my posts above. Again, much luck.

[j2me64]

the main error you have in your code is already been mentioned by fubarable

(constructors should have no return type, [b]not even void)[/b]

and i renamed your method name() to toString() so that this Object method is overriden and returns you string concatenation instead of a strange hashcode;). here is the the code that produce this output

Identification Number 111.0
Product Name Product 1
Units In Stock 50.0
Unit Price 500.0
Inventory Value 25000.0

i don't used the scanner, instead i instantiate the inventory directly. so with this code you can store only one product. but you can easily enhance it by adding a collection for your products and the appropriate methods add, remove and so on.

package myjava.examples.org;

class Inventory {

	private String name;// product name
	private int number;// item number
	private int units;// units available
	private double price;// price per unit

	public Inventory(String nameIn, int numberIn, int unitsIn, double priceIn) {

		setName(nameIn);
		setNumber(numberIn);
		setUnits(unitsIn);
		setPrice(priceIn);
		// setValue (valueIn);

	} // End initialization constructor Product

	// Declare Set/Get Methods
	public void setName(String nameInput) {

		name = nameInput;

	} // End method setName

	public void setNumber(int numberInput) {
		number = numberInput;

	} // End method setNumber

	public void setUnits(int unitsInput) {
		units = unitsInput;
	}

	public void setPrice(double priceInput) {
		price = priceInput;
	} // End method setPrice

	public String getName() {
		return (name);
	} // End method getName

	public double getNumber() {
		return (number);
	} // End method getNumber

	public double getUnits() {
		return (units);
	} // End method getUnits

	public double getPrice() {
		return (price);
	} // End method getPrice

	public double InventoryValue() {
		return (units * price);

	} // End method InventoryValue

	// toString()Method

	// Returns a formatted String for output purposes

	public String toString() {
		String formatString = "Identification Number " + getNumber() + "\n";
		formatString += " Product Name " + getName() + "\n";
		formatString += " Units In Stock " + getUnits() + "\n";
		formatString += " Unit Price " + getPrice() + "\n";
		formatString += "Inventory Value " + InventoryValue() + "\n";

		return formatString;

	}// End name()
	
	public static void main (String args [] )

	{

	Inventory p = new Inventory ("Product 1", 111, 50, 500.00 );


	System.out.printf (p.toString () );
	}
	}//End InventoryApplication
