Not able to see another window after running form in swing

Question

here is the code of my FlashForm.java

package main.java.com.lecture_backup.view;
public class FlashForm extends javax.swing.JFrame implements Runnable {

    /**
     * Creates new form FlashForm
     */
    public FlashForm() {
        initComponents();

        new Thread(this).start();
    }

    @Override
    public void run() {
        for (int i = 0; i <= 100; i++) {
            try {
                jProgressBar1.setValue(i);
                Thread.sleep(100);
            } catch (Exception ex) {
            }
        }
        new main.java.com.lecture_backup.view.HomePage().setVisible(true);
        dispose();
    }

After running the project which has FlashForm.java as its main class I am not able to see HomePage. Can you please tell me what is the reason for it is not going on HomePage after running this file? I would also like to know what changes should I do to this code for better code writing practice.
