import java.lang.*;
public class pdatest2 extends javax.swing.JFrame { 
    /** Creates new form pdatest2 */
    public static void main(String args[]) {
        new pdatest2().show();
    }
   
    public pdatest2() {
        initComponents();
    }
    /** This method is called from within the constructor to
    * initialize the form.
    * WARNING: Do NOT modify this code. The content of this method is
    * always regenerated by the Form Editor.
    */
    private void initComponents() {
        jButton1 = new javax.swing.JButton();

        addWindowListener(new java.awt.event.WindowAdapter() {
            public void windowClosing(java.awt.event.WindowEvent evt) {
                exitForm(evt);
            }
        });

        jButton1.setText("Hello press");
        jButton1.setToolTipText("null");
        getContentPane().add(jButton1, java.awt.BorderLayout.CENTER);

        pack();
    }
   
    /** Exit the Application */
    private void exitForm(java.awt.event.WindowEvent evt) {
        System.exit(0);
    }
   
    /**
    * @param args the command line arguments
    */
