Boa tarde, gostaria de ao tentar fechar meu sistema ele começe a fazer um backup do DB.GDB, enquanto ele copia o db eu qria que aparecesse um JDialog que crieu, depois que terminasse gostaria que fechasse o JDialog e tbm…

Criar Thread para fazer backup e mostrar Jdialog com progress bar indeterminate

fiz da seguinte maneira, funcionando tá mas qro saber se ta correto.

classe carregando.java

package Grafica;

/**

public class carregando extends javax.swing.JDialog {

    /** Creates new form carregando */
    public carregando(java.awt.Frame parent, boolean modal) {
        super(parent, modal);
        initComponents();
        setLocationRelativeTo(null);
        setResizable(false);
        progress.setIndeterminate(true);
        RunnableThread thread = new RunnableThread();
        Thread threadR = new Thread(thread);
        //Thread threadC = new Thread(thread);

        threadR.start();
    }
