Thread: I need help with my Netbeans calculator code

I am trying to create a retail calculator that will show sales prices of items. A user enters the original price of the item in a text box, and the percentage discounted in another box. The user then clicks the calculate button to get the answer. My problem is that I cannot get the program to calculate the answer, instead I am getting a lot of error messages. I cannot figure out how to solve these issues. Below is the codes I have:

import javax.swing.JOptionPane;

/**

public class RetailCalcForm extends javax.swing.JFrame {

private void close() {
throw new UnsupportedOperationException("Not yet implemented");
}

private static class number {

public number() {
}
}

private static class number2 {

public number2() {
}
}

/**

*/
public RetailCalcForm() {
initComponents();
}
