Difference between JDialog and a new window

Question

Hello,
I have GUI window which contain maybe 10 buttons, and for each of them I add an event listener. When different button clicked, it open a new window which allow user to enter some value. I didn´t use dialog, I did like :
Button1.setFont(new java.awt.Font("Arial", 0, 12));
Button1.setText("Button1");
getContentPane().add(Button1, new FlowLayout());
Button1.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
Button1ActionPerformed(evt);
public void Button1ActionPerformed(java.awt.event.ActionEvent evt){   
new window1();
public class window1 extends JFrame {
// this class is a new window not a dialog.
// add some buttons and textField so user can enter some number to text field.
Button 1 --> open window 1
Button 2--> open window 2
Button 3-->open window 3
My problem is, only one button works. Button 2 and 3 are not working even I did the same thing to them as button 1. Do you think I should change window1 into dialog?
I have also problem with netBeans. My netBeans seems always remember my old executed code. For example if I delete button 1 listener, and run it. Button 1 still works even the code not existing anymore. Has anybody experience the same. I am really angry about this issue. Can anybody help me?
Thanks in advance!

hello,
Where can I set this Build Automatically property?
I didn´t use dialog, instead I create a new frame. here is code.
import javax.swing.*;
import java.awt.event.*;
import java.lang.Math.*;
public class Class2 extends JFrame{
      JTextField text1= new JTextField(20);
      JTextField text2 = new JTextField(20);
      JTextArea text3 = new JTextArea(5,8);
      JLabel label1 = new JLabel();
      JLabel label2 = new JLabel();
      JLabel label4 = new JLabel();
      JLabel label5 = new JLabel();
      JButton showResult = new JButton();
      JButton ok = new JButton();
       public Class2(Class1 c){
      cl = c;
      setSize(400,300);
      setTitle("Class2");
      getContentPane().setLayout(new FlowLayout());
      label1.setFont(new java.awt.Font("Arial", 0, 12));
      label1.setText("Total ");
      getContentPane().add(label1, new FlowLayout());
       text1.setFont(new java.awt.Font("Arial",0,12));
      text1.setBounds(5, 8, 5, 5);
      text1.setEditable(true);
      getContentPane().add(text1, new FlowLayout());
       // add text field2
      text2.setFont(new java.awt.Font("Arial",0,12));
      text2.setBounds(5, 8, 5, 5);
      getContentPane().add(text2, new FlowLayout());
      text2.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                text2Performed(evt);
      label2.setFont(new java.awt.Font("Arial", 0, 12));
      label2.setText("Press enter");
      label2.setToolTipText("Press Enter");
      getContentPane().add(label2, new FlowLayout());
      label4.setFont(new java.awt.Font("Arial", 0, 12));
      label4.setText("type number");
      getContentPane().add(label4, new FlowLayout());
      // add text field3
      text3.setFont(new java.awt.Font("Arial",0,12));
      text3.setBounds(5, 8, 5, 5);
      text3.setEditable(false);
      //text1.setText(Roadpeople);
      getContentPane().add(text3, new FlowLayout());
      label5.setFont(new java.awt.Font("Arial", 0, 12));
      label5.setText("Count ");
      getContentPane().add(label5, new FlowLayout());
      // add showResultButton
      showResult.setFont(new java.awt.Font("Arial", 0, 10));
      showResult.setToolTipText("show result");
      showResult.setLabel("show result");
      showResult.setMargin(new java.awt.Insets(2, 2, 2, 2));
      getContentPane().add(showResult, new FlowLayout());
      // add ok button
      ok.setFont(new java.awt.Font("Arial", 0, 10));
      ok.setToolTipText("ok");
      ok.setLabel("ok");
      ok.setMargin(new java.awt.Insets(2, 2, 2, 2));
      getContentPane().add(ok, new FlowLayout());
      setVisible(true);
       }Thanks
