Duvida botao para abrir um frame e fechar o antigo

Bom Pessoal

Tenho uma aplicação bem simples que ao gerar um evento em um botão o programa abre um novo frame como faço pra ele abrir o novo frame e fechar o frame antigo sendo que ele o frame principal se eu fecha lo manualmente ele encerra o programa.Segue abaixo todo o código do frame que aciona o botão ou seja tela01.

Agradeço antecipadamente e aguardo respostas.

public class tela01 extends javax.swing.JFrame {

public tela01() {
    initComponents();
}

              
private void initComponents() {

    jButton1 = new javax.swing.JButton();
    jLabel1 = new javax.swing.JLabel();
    jTextField1 = new javax.swing.JTextField();
    jButton2 = new javax.swing.JButton();
    jLabel2 = new javax.swing.JLabel();

    jButton1.setText("jButton1");

    jLabel1.setText("Programa tela 01");

    jTextField1.setText("Programa de Cadastro ");

    setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

    jButton2.setText("Cadastrar Clientes");
    jButton2.addActionListener(new java.awt.event.ActionListener() {
        public void actionPerformed(java.awt.event.ActionEvent evt) {
            jButton2ActionPerformed(evt);
        }
    });

    jLabel2.setText("Programa de Cadastro");

    javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
    getContentPane().setLayout(layout);
    layout.setHorizontalGroup(
        layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
        .addGroup(layout.createSequentialGroup()
            .addGroup(layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
                .addGroup(layout.createSequentialGroup()
                    .addContainerGap()
                    .addComponent(jButton2))
                .addGroup(layout.createSequentialGroup()
                    .addGap(160, 160, 160)
                    .addComponent(jLabel2)))
            .addContainerGap(132, Short.MAX_VALUE))
    );
