Using the Box class

[Neoco]

I'm still working on my computer science summative and now I need help with shifting my components downward

summative:

import java.awt.*; import javax.swing.*; public class conceptstemplate extends JApplet {         Box sidebar = new Box (BoxLayout.LINE_AXIS);                 JButton next = new JButton ("Next >");         JButton previous = new JButton ("< Previous");         JButton mmenu = new JButton ("Main Menu");                 public void init ()         {                 setSize (1000, 600);                 setBackground (Color.lightGray);                                                 //sidebar.add (Box.createRigidArea (new Dimension (50, 450)));                 //sidebar.add (Box.createVerticalStrut (450));                 //sidebar.setBounds (0, 450, getWidth (), 150);                 //sidebar.add (Box.createHorizontalGlue ());                                 sidebar.add (Box.createHorizontalStrut (50));                 sidebar.add (mmenu);                 sidebar.add (Box.createHorizontalStrut (600));                 sidebar.add (previous);                 sidebar.add (Box.createHorizontalStrut (50));                 sidebar.add (next);                                 add (sidebar);         } }

This is supposed to create a few buttons at the bottom of the screen. What I'm having trouble with is shifting these buttons to the bottom of the screen. The methods with the "//" next to them are the methods I have tried using and that haven't worked. Help please?
