how to implement simply a progress bar

[Allgorythm]

i want to see the progress of searching the value in my table, but I dont have any idea how. what im thinking now is maybe there is something to do with threads. i dont know anything about threads its too far from what i learned now. pleas help me with this one.

public class ProgressSample extends JFrame {
    
    public ProgressSample() {

        ProgressBar monitor = new ProgressBar();
        JPanel panel = new JPanel();
        final JTextField searchField = new JTextField();
        panel.setLayout(null);

        final String[] columns = {"Name", "Surname", "Age"};

        Object[][] values = {{"Jhon", "Java", "23"}, {"Stupid", "Stupido", "500"},
                                {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                                {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                                {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                                {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                                {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                                {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                                {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                                {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                                {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                                {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                                {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                                {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                                {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                                {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                                {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                                {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                                {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},

                                {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                                {"Max", "Dumbass", "10"}, {"Melanie", "Martin", "500"},
                                {"Jollibe", "Mcdonalds", "15"}};

        final JTable mainTable = new JTable(values, columns);
        
        mainTable.setColumnSelectionAllowed(true);
        mainTable.setRowSelectionAllowed(true);

        JScrollPane scroll = new JScrollPane(mainTable);
        scroll.setBounds(0, 100, 900, 500);

        searchField.setBounds(10, 50, 150, 20);
        searchField.addActionListener(new ActionListener() {

            public void actionPerformed(ActionEvent e) {

                // set the column selection to false to gain multiple row selection
                mainTable.setColumnSelectionAllowed(false);

                // clear the selection for the next search, so the table wont
                // be flooded by selection highlight.
                mainTable.clearSelection();

                String value = searchField.getText();

                for (int row = 0; row <= mainTable.getRowCount() - 1; row++) {

                    for (int col = 0; col <= mainTable.getColumnCount() - 1; col++) {

                        if (value.equals(mainTable.getValueAt(row, col))) {

                            // this will automatically set the view of the scroll in the location of the value
                            mainTable.scrollRectToVisible(mainTable.getCellRect(row, col, true));

                            // this will automatically set the focus of the searched/selected row/value
                            mainTable.addRowSelectionInterval(row, row);
                        }
                    }
                }
            }
        });

        monitor.setBounds(300, 50, 200, 20);

        panel.add(monitor);
        panel.add(searchField);
        panel.add(scroll);

        getContentPane().add(panel);
