Thread: Using Integer.parseInt

Hi there, im having problem converting my string to integer..

Basically my program is a dispenser that holds items, there price and quantity I can manipulate these through txtbox's which are defined as arrays and then i show them using a txtarea.

My currently problem is that im wanting to show the price of my items through the txt area I can display my items names as follows

for(int i =0; i<myDispenser.length; i++){
			String itemName = txtadditem[i].getText();
I then call my items names;
 
output = output + "  Product Name "+ ":" +  myDispenser[i].getItemName();

For my items price which are currently declared as int I am trying to do the following

String Price = txtprice[i].getText();
			itemPrice = Integer.parseInt(Price);

however I get this error
Exception in thread "AWT-EventQueue-0" java.lang.NumberFormatException: For input string: ""
at java.lang.NumberFormatException.forInputString(Unk nown Source)
at java.lang.Integer.parseInt(Unknown Source)
at java.lang.Integer.parseInt(Unknown Source)

I've been trying for several days and still cant see my problem any help would be appreciated if my code that I have displayed is insufficient please say so..

Many thanks
