shopping [] shop = new shopping[100];
        PrintWriter ofile = null;
        String pname;
        double pprice;
        int pbarcode;
        int pquantity;
        int cmd;
        boolean done;
        String resp = JOptionPane.showInputDialog( "Choose from:" +
                "\n1: Add new products\n2: Shop\n3: Check out ");
        cmd = Integer.parseInt(resp);
        switch(cmd){
        case 1: done = false;
                int i = 0;
                while(!done){
                    pname = JOptionPane.showInputDialog("Enter the product name");
                    pquantity = JOptionPane.showInputDialog("Enter the quantity of that product");
                    shop p = new shop(pname);

So I am trying to write a program that allows you to go shopping. I am having a problem where I have pquantity = JOptionPane... It keeps telling me to use and int not a string but I have pquantity as an int. HELP?!

Ok so pquantity is an int, which is right. However, JOptionPane.... returns a string.

Use Integer.parseInt(JOptionPane.showInput...)

edit: also please put your code between code tags in the future. I'd edit it for you, but I'm powerless in the Java forum.

Here pquantity = JOptionPane.showInputDialog("Enter the quantity of that product");, JOptionPane.showInputDialog() returns a String. The pquantity variable is an int. So you have to parse the String to an int before assigning it to pquantity.
