    Unhappy JAVA need fix the code

    hi guys. I am new to java and I have problems with my java codes. Can anyone help me fix it. Thank You.

    the ouput should be like this:

    Fee Calculator
    ID Code: [Text Box]
    Weight: [Text Box]
    Rate: [$1.02]
    Price Charge: [$ ]

    my code:

    import java.awt.Color;
    import java.awt.Font;
    import java.awt.event.ActionEvent;
    import java.awt.event.ActionListener;

    import javax.swing.*; //Needed for swing components

    public class PayrollApplication extends JFrame
    implements ActionListener
    {
    //declare your instance objects here
    JPanel mainPanel = new JPanel();
    JLabel label1 = new JLabel("Fee Calculator");
    JLabel IDcode = new JLabel("ID Code: ");
    JLabel Weight = new JLabel ("Weight: ");
    JLabel Rate = new JLabel ("Rate: ");
    JLabel priceCharge = new JLabel ("Price Charge: ");
    JTextField label1Field = new JTextField(20);
    JTextField IDCodeField = new JTextField(20);
    JTextField WeighttField = new JTextField(20);
    JTextField RatetField = new JTextField(20);
    JTextField PricetField = new JTextField(20);
    JButton calculateButton = new JButton("Calculate Shipping Fee");
    JTextArea outputTextArea = new JTextArea(5, 20);
    JScrollPane outputScrollPane = new JScrollPane(outputTextArea); //For scroll bars around text area

    Font bigFont = new Font("Times New Roman", Font.BOLD, 28);

    // This is the first method called in a application
    //We will create an object of ourselves to call the
    //constructor and then set the default close operation for the frame
    public static void main(String[] args)
    {

    PayrollApplication basicGUI = new PayrollApplication();
    basicGUI.setDefaultCloseOperation(JFrame.EXIT_ON_C LOSE);

    }//end of main

    //This is the constructor for this class. It will be called from main
    //It will set up our GUI panel with needed components
    //and set up appropriate event listening
    public PayrollApplication()
    {
    //call the superclass' constructor and send a title
    super("Fee Calculator");

    //add GUI components to the appropriate container
    mainPanel.add(label1);
    label1.setFont(bigFont);
    label1.setForeground(Color.RED);
    mainPanel.add(IDcode);
    mainPanel.add(Weight);
    mainPanel.add(Rate);
    mainPanel.add(priceCharge);
    mainPanel.add(calculateButton);
    mainPanel.add(outputScrollPane);
    JTextField IDCodeField = new JTextField(20);
    JTextField WeighttField = new JTextField(20);
    JTextField RatetField = new JTextField(20);
    JTextField priceChargetField = new JTextField(20);

    //add the JPanel to the JFrame
    add(mainPanel);

    //call the listener method
    addListeners();

    //set the properties of the JFrame for display
    this.setSize(300, 500);
    this.setVisible(true);
    }//end of constructor

    //use to register the components to the action listener
    public void addListeners()
    {
    calculateButton.addActionListener(this);
    }

    //Retrieve and convert text fields and calculate and display the gross pay
    public void addPerformed(ActionEvent evt)
    {
    double Weight = 0,Rate,priceCharge;
    Rate = 0.12;
    priceCharge = (Weight * Rate);
    String sign = "$";

    String.format("%s%2d", sign, priceCharge);
    }

    }//end of class

    Default Re: JAVA need fix the code

    OK, what we have here is your code and your requirements and not much else but "help me fix it".

    Please understand that we're all volunteers who offer help on our own free time, and so we greatly appreciate all efforts you can put in towards making it easiser for us to help you. Would it be asking too much for you to put more effort into asking your question? For instance by telling us what behaviors you're seeing now, what attempts you've made to solve your problem, how they didn't work, any and all error messages. Also, please edit your post and add [code] [/code] tags around your posted code so that it retains its formatting and is readable.

    Your efforts in fixing this are greatly appreciated.

    Indeed. Original poster, please do not needlessly divide the discussion of your problem as this is grossly unfair to all of us.

    Locking this thread.
