public class SwingTester {
   public static void main(String[] args) {
      createWindow();
   }

   private static void createWindow() {
      JFrame frame = new JFrame("Swing的GridLayout示例");
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      createUI(frame);
      frame.setSize(560, 200);
      frame.setLocationRelativeTo(null);
      frame.setVisible(true);
   }

   private static void createUI(final JFrame frame){
      JPanel panel = new JPanel();
      GridLayout layout = new GridLayout(0,3);
      layout.setHgap(10);
      layout.setVgap(10);

      panel.setLayout(layout);
      panel.add(new JButton("按鈕 1"));
      panel.add(new JButton("按鈕 2"));
      panel.add(new JButton("按鈕 3"));
      panel.add(new JButton("按鈕 4"));
      panel.add(new JButton("按鈕 5"));
      frame.getContentPane().add(panel, BorderLayout.CENTER);
   }
