I'm currently working on a project, I'll try to subrscibe first. I save data into text file, that I use as a source for browser of that data. The browser is based on table that contains the data. I have to rewrite the source file everytime I delete or edit data. That's where the problem comes in. After deleting or editing data I call a method to create the table again, but the table never creates. Is it possibly made by editing the file and calling the method right after that? If I restart my app the table is successfully created with right data. Take in note that I don't get any error message.

This is the method I use for loading data from source file:

try (BufferedReader input1 = new BufferedReader(new FileReader("./src/data.src"))) {
        int lines = 0;
        while (input1.read() != -1) {
            if (!(input1.readLine()).equals("")) {
                lines++;
            }
        }
        input1.close();
        if (lines == 0) {
            JOptionPane.showMessageDialog(null, "No data to load, create a note first!");
            new Writer().build(frame);
        } else {
            try (BufferedReader input = new BufferedReader(new FileReader("./src/data.src"))) {
                Game[] g = new Game[lines];
                String currentLine;
                String[] help;
                int counter = 0;
                while (lines > 0) {
                    currentLine = input.readLine();
                    help = currentLine.split("#");
                    g[counter] = new Game(help[0],help[1], help[2], help[3], help[4], help[5], help[6], help[7], help[8], help[9]);
                    counter++;
                    lines--;
                }
                input.close();
                final JButton bButton = new backButton().create(frame, mPanel);
                build(g, frame, bButton);
                mPanel.add(panel);
                mPanel.add(panel2);
                mPanel.add(searchPanel);
                mPanel.add(bButton);
                bButton.addActionListener(new ActionListener() {
                    @Override
                    public void actionPerformed(ActionEvent e) {
                        frame.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
                        panel.removeAll();
                        frame.setCursor(Cursor.getDefaultCursor());
                    }
                });
                mPanel.setPreferredSize(new Dimension(1000, 750));
                panel.setBorder(new EmptyBorder(10, 10, 10, 10));
                frame.setLayout(new FlowLayout());
                frame.add(mPanel);
                frame.pack();
                JMenuBar menuBar = new Menu().create(frame, mPanel);
                frame.setJMenuBar(menuBar);
                frame.setVisible(true);
                Rectangle rec = GraphicsEnvironment.getLocalGraphicsEnvironment().getMaximumWindowBounds();
                int width = (int) rec.getWidth();
                int height = (int) rec.getHeight();
                frame.setBounds(1, 3, width, height);
                frame.addComponentListener(new ComponentAdapter() {
                    @Override
                    public void componentMoved(ComponentEvent e) {
                        frame.setLocation(1, 3);
                    }
                });

And this is the method I use for creating the table:

String[][] tableData = new String[g.length][9];
    for (int i = 0; i < tableData.length; i++) {
        tableData[i][0] = g[i].getChampion();
        tableData[i][1] = g[i].getRole();
        tableData[i][2] = g[i].getEnemy();
        tableData[i][3] = g[i].getDifficulty();
        tableData[i][4] = g[i].getResult();
        tableData[i][5] = g[i].getScore();
        tableData[i][6] = g[i].getGameType();
        tableData[i][7] = g[i].getPoints();
        tableData[i][8] = g[i].getLeague();
    }
    final JLabel searchLabel = new JLabel("Search for champion played.");
    final JButton searchButton = new JButton("Search");
    final JTextField searchText = new JTextField(20);
    frame.setTitle("LoL Notepad - reading your notes");
    JTable table = new JTable(tableData, columnNames);
    final JScrollPane scrollPane = new JScrollPane(table);
    scrollPane.setPreferredSize(new Dimension(980, 500));
    panel2.setPreferredSize(new Dimension(1000, 550));
    panel2.setVisible(false);
    panel2.setBorder(new EmptyBorder(10, 10, 10, 10));
    panel3.setVisible(false);
    panel.setLayout(new FlowLayout());
    panel.add(scrollPane);
    searchPanel.add(searchLabel);
    searchPanel.add(searchText);
    searchPanel.add(searchButton);
    searchButton.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            try {
                frame.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
                search(g, searchText.getText(), frame, bButton);
                frame.setCursor(Cursor.getDefaultCursor());
            } catch (IOException ex) {
                Logger.getLogger(Reader.class.getName()).log(Level.SEVERE, null, ex);
            }
        }
    });
    table.addMouseListener(new MouseAdapter() {
        @Override
        public void mousePressed(MouseEvent e) {
            if (e.getClickCount() == 1) {
                JTable target = (JTable) e.getSource();
                panel.setVisible(false);
                searchPanel.setVisible(false);
                bButton.setVisible(false);
                int row = target.getSelectedRow();
                specific(row, g, frame, bButton);
            }
        }
    });
