Creating a BoxLayout

BoxLayout has a single constructor: public BoxLayout(Container target, int axis) public BoxLayout(Container target, int axis) The first argument is the container The second is the layout direction. Valid directions are BoxLayout.X_AXIS for a left-to-right layout and BoxLayout.Y_AXIS for a top-to-bottom layout. A BoxLayout and container are bound together in two directions, import java.awt.LayoutManager; import javax.swing.BoxLayout; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; public class BoxLayoutDemo {   public static void main(String[] a) {     JFrame frame = new JFrame();     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);     JPanel panel = new JPanel();     LayoutManager layout = new BoxLayout(panel, BoxLayout.X_AXIS);     panel.setLayout(layout);     panel.add(new JLabel("a"));     panel.add(new JLabel("b"));     panel.add(new JLabel("c"));     panel.add(new JLabel("d"));     panel.add(new JLabel("e"));     panel.add(new JLabel("f"));     frame.add(panel);     frame.setSize(300, 200);     frame.setVisible(true);   } }
