    Default Filter JTable using andFilter and orFilter

    hi, I am trying to use andFilter and orFilter simultaneously, Is it possible?
    My aim here is not to hide the row that has "MONITORS" and "MOUSE" on column#1.
    Here is a sample code of what I am trying to do, in rowFilter() method I commented the line that I am stacked-up
    import java.awt.BorderLayout;
    import java.util.ArrayList;
    import javax.swing.*;
    import javax.swing.event.DocumentEvent;
    import javax.swing.event.DocumentListener;

    public class AndOrFilter extends JFrame
    {
        private JPanel pnlFrame, pnlFields;
        private JTable table;
        private JTextField text1, text2;
        private JLabel label1, label2;
     
        public AndOrFilter()
        {
            setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            initComponents();
            addDocListener();
            pack();
        }
     
        private void initComponents()
        {
            pnlFields = new JPanel();
     
            label1 = new JLabel("BRAND: ");
            pnlFields.add(label1);
            text1 = new JTextField(25);
            pnlFields.add(text1);
            label2 = new JLabel("MODEL: ");
            pnlFields.add(label2);
            text2 = new JTextField(25);
            pnlFields.add(text2);
