title: Adding JButton on JToolbar vertically
body: <p>I want to add more buttons on <code>JToolbar</code> but I could not add button one on another vertically; rather they are aligning themselves automatically horizontally.</p>
  
  <pre class="lang-java prettyprint-override"><code>public class Interface 
  {
  JTable tableT = new JTable();
  private JTable table;
  
    public Interface()
    {
     final JFrame f= new JFrame("Content Provider Generator");
     f.setFont(new Font("Aharoni", Font.BOLD, 12));
     f.setForeground(Color.GRAY);
     f.getContentPane().setBackground(Color.WHITE);
  
       JToolBar toolBar = new JToolBar();
        f.getContentPane().add(toolBar, BorderLayout.EAST);
  
    //MenuButton//
        JButton button = new JButton();
  button.setIcon(new ImageIcon
          (Interface.class.getResource("/javax/swing/plaf/metal/icons/ocean/menu.gif")));
        toolBar.add(button);   //added to JToolbar
  
        JPopupMenu popupMenu = new JPopupMenu();
        addPopup(button, popupMenu);
  
        //Jpopupmenu
        JMenuItem mntmNewMenuItem = new JMenuItem("Table");
  
        JButton button1 = new JButton();
      button.setIcon(newImageIcon
          (Interface.class.getResource("/javax/swing/plaf/metal/icons/ocean/menu.gif")));
        toolBar.add(button1);
  }
  }
