Java Swing - makeTextPanel() method for tabbedpane

Question

Where is this method from? I've tried looking for it and i cant find it. The only example i've seen it used in was where JPanel is extended and it is called in the constructor. The problem is i do not want to extend JPanel so how do i go about creating an object(my question is what class) so that i can access this method? I don't know where JPanel inherited this method from.

JComponent panel1 = makeTextPanel("Panel");
tabs.addTab("Display", panel1);

It is from here: TabbedPaneDemo.java which can be found under the heading: "Code for Tabbed Panes" on that page .

protected Component makeTextPanel(String text) {
    JPanel panel = new JPanel(false);
    JLabel filler = new JLabel(text);
    filler.setHorizontalAlignment(JLabel.CENTER);
    panel.setLayout(new GridLayout(1, 1));
    panel.add(filler);
    return panel;
}

You don't have to extend anything. You can make it static .
