public class SwingTester {
   public static void main(String[] args) {
      createWindow();
   }

   private static void createWindow() {    
      JFrame frame = new JFrame("Swing Tester");
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      createUI(frame);
      frame.setSize(560, 200);      
      frame.setLocationRelativeTo(null);  
      frame.setVisible(true);
   }

   private static void createUI(final JFrame frame){  
      JPanel panel = new JPanel();
      LayoutManager layout = new FlowLayout();  
      panel.setLayout(layout);       

      JButton button = new JButton("Click Me!");
      final JLabel label = new JLabel();

      button.addActionListener(new ActionListener() {
         @Override
         public void actionPerformed(ActionEvent e) {
            JFileChooser fileChooser = new JFileChooser();
            int option = fileChooser.showSaveDialog(frame);
            if(option == JFileChooser.APPROVE_OPTION){
               File file = fileChooser.getSelectedFile();
               label.setText("File Saved as: " + file.getName());
