I'm creating a program to keep track of a list of DVD's. On the main page I have set up 2 JButtons. When the user clicks the one that says new, a new JFrame from another class comes up with fields to enter information about a new DVD. I'm trying to make a cancel button on this second frame work so that when one clicks the cancel button, it brings back up the main GUI and closes the new entry GUI. Code is below, I cant figure out how to do it.

Main GUI page

package dvdlibrary;

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JOptionPane;


public class bootPage extends javax.swing.JFrame {

    /** Creates new form bootPage */
    public bootPage() {
        initComponents();
    }



    @SuppressWarnings("unchecked")

    private void initComponents() {

        jLabel1 = new javax.swing.JLabel();
        jLabel2 = new javax.swing.JLabel();
        jButton1 = new javax.swing.JButton();
        jButton2 = new javax.swing.JButton();

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
        getContentPane().setLayout(new org.netbeans.lib.awtextra.AbsoluteLayout());

        jLabel1.setText("DVD Library");
        getContentPane().add(jLabel1, new org.netbeans.lib.awtextra.AbsoluteConstraints(168, 11, -1, -1));

        jLabel2.setText("What would you like to do today?");
        getContentPane().add(jLabel2, new org.netbeans.lib.awtextra.AbsoluteConstraints(113, 70, -1, -1));

        jButton1.setText("Create Record");
        jButton1.addMouseListener(new java.awt.event.MouseAdapter() {
            public void mouseClicked(java.awt.event.MouseEvent evt) {
                jButton1MouseClicked(evt);
            }
        });
        jButton1.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                jButton1ActionPerformed(evt);
            }
        });
        getContentPane().add(jButton1, new org.netbeans.lib.awtextra.AbsoluteConstraints(50, 135, -1, -1));

        jButton2.setText("View Library");
        jButton2.addMouseListener(new java.awt.event.MouseAdapter() {
            public void mouseClicked(java.awt.event.MouseEvent evt) {
                jButton2MouseClicked(evt);
            }
        });
        getContentPane().add(jButton2, new org.netbeans.lib.awtextra.AbsoluteConstraints(224, 135, 111, -1));

        pack();
    }// </editor-fold>                        

    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         




    }                                        

    private void jButton1MouseClicked(java.awt.event.MouseEvent evt) {                                      
      if(evt.getSource()== jButton1)
           dvdlibrary.createEntry.createE();


    }                                     

    private void jButton2MouseClicked(java.awt.event.MouseEvent evt) {                                      
       if(evt.getSource()== jButton2)
           dvdlibrary.movieChooser.movChoo();
    }                                     


    public static void bootP() {
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new bootPage().setVisible(true);
                new bootPage().setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            }
        });
    }

    // Variables declaration - do not modify                     
    private javax.swing.JButton jButton1;
    private javax.swing.JButton jButton2;
    private javax.swing.JLabel jLabel1;
    private javax.swing.JLabel jLabel2;


}

Create Entry page

    public createEntry() {
        initComponents();
    }


    @SuppressWarnings("unchecked")

    private void initComponents() {

        jButton2 = new javax.swing.JButton();
        jButton3 = new javax.swing.JButton();
        jButton4 = new javax.swing.JButton();

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

        jLabel2.setText("Genre");

        jLabel3.setText("Length");

        jLabel4.setText("Rating");

        jLabel6.setText("Year");

        jComboBox1.setModel(new javax.swing.DefaultComboBoxModel(new String[] { "Item 1", "Item 2", "Item 3", "Item 4" }));

        jTextArea1.setColumns(20);
        jTextArea1.setRows(5);
        jScrollPane1.setViewportView(jTextArea1);

        jButton1.setText("Input");

I think you can also use DISPOSE_ON_CLOSE:

DISPOSE_ON_CLOSE (the default for JInternalFrame)

Hide and dispose of the window when the user closes it. This removes the window from the screen and frees up any resources used by it.
