Hi all,

I was wondering if you could help me with the following problem. I need help adding the prices together, I am confused on what the code is. The following code is correct, just I don't know how to add the prices together. e.g.

2 waters and 1 food equals 3.15

Code:
public void actionPerformed(ActionEvent e) {

DecimalFormat pound= new DecimalFormat("#.##"); 

select= (String) JOptionPane.showInputDialog   
  (project.this,"Select",
   Select,JOptionPane.INFORMATION_MESSAGE, null, products, 
   "food");
                   
            if (select.equals("food"))
           	   price = 0.65;
              
              else if (select.equals("water"))
           	   listprices = 1.25;
              
              else 
           	   price = 0.0;
                        
   listmodel.addElement(select+ " " +pound.format(price));
}
Thanks in advance,

hypon
