I need to use the args[2] instead of the 1.12 in balloon 2 same for args[0] and args[1] but that's for later in the program. There is a frame and everything I removed them, thought the site was asking me to do so.

import javax.swing.*;

import java.awt.*;



public class ProportionalBalons extends JPanel {



    public void runArguments(String args) {

        String currencyCostumerHas = args[0];

        String currencyCostumerWants = args[1];

        String USDollarToEUEuroexchangeValueS = args[2];

        int exchangeValue = new Integer(USDollarToEUEuroexchangeValueS).intValue();

    }





    public void paintComponent(Graphics g) {

        double balon1Diameter = costumerDeposit;

        double balon2Diameter = costumerDeposit * 1.12;

        //ballon 1

        g.drawOval(10, 10, balon1Diameter, balon1Diameter);

        //ballon 2 

        g.drawOval(60 * 8, 10, balon2Diameter, balon2Diameter);



    }

} 

You need to capture the information you get from runArguments. I think actually what you want is a constructor:

public class ProportionalBalons extends JPanel {

    private String currencyCostumerHas;

    private String currencyCostumerWants;

    private double exchangeRate = args[2];



    public ProportionalBalons(int currencyCustumerHas, String currencyCustumerWants, exchangeRate) {

        this.currencyCostumerHas = currencyCostumerHas;

        this.currencyCostumerWants = currencyCostumerWants;

        this.exchangeRate = exchangeRate;

    }



    public void paintComponent(Graphics g) {

        double balon1Diameter = costumerDeposit;

        double balon2Diameter = costumerDeposit * exchangeRate;

        //ballon 1

        g.drawOval(10, 10, balon1Diameter, balon1Diameter);

        //ballon 2 

        g.drawOval(60 * 8, 10, balon2Diameter, balon2Diameter);

    }

}

Here, when you create a new ProportionalBalons object, you will capture the values of your arguments and they will be available to all the methods defined in ProportionalBalons.

A few notes:

1. I didn't see any use of the "currency" variables, but I put them in there because it looks like you probably do actually need them.


2. There is no definition of the customerDeposit in your existing code; I assume it's somewhere. If you must, you can capture it in the constructor as well.


3. The exchange rate certainly shouldn't be an int. If the USD is either 1x or 2x EUR, then I'll pick 1x, please (I get paid in USD). I've made this a double.

If your args variable is declared and initialized outside of your paintComponent() and runArguments() methods then you should be able to call it from within paintComponent.

double balon2Diameter=costumerDeposit*args[2];

If the variable is only local then it won't work.
