Draw in a JPanel subclass.
1. Create a customized subclass of JPanel
public class MyDrawPanel extends JPanel {   //or a class in JApplet subclass file
  public void paintComponent( Graphics g ) {
    super.paintComponent( g );
    //g drawing stuff here
  }
  public void draw (whatever args you need ) {
    //stuff
    repaint();   //calls paintComponent
  }
}
2. In your JApplet subclass:
  private MyDrawPanel myPanel;
  public void init () {
    myPanel = new MyDrawPanel();
    myPanel.setBackground( Color )     //if wanted
    container.add( myPanel, layout_area )
    myPanel.draw( your args )

JSlider mySlider = new JSlider( SwingConstants.HORIZONTAL, min, max, starting )
mySlider.setMajorTickSpacing( int )
mySlider.setPaintTicks( true )
mySlider.getValue()    //returns int where the slider's at
arrow keys, page up/down, home, end work with focused JSlider
myslider.addChangeListener( object that implements ChangeListener )
                           public void stateChanged( ChangeEvent )

JMenuItem item1 = new JMenuItem( String )
item1.setMnemonic( char )

JRadioButtonMenu radio1 = new ItemJRadioButtonMenuItem( String )
radio1.setSelected( true )   //if wanted
radio1.addActionListener(object that implements ActionListener ) //unlike JRadioButton
radio1.isSelected()     //returns boolean
radio1.getText()        //returns String
ButtonGroup group1 = new ButtonGroup()
group1.add( radio1 )    
menu2.add( radio1 )

menu1.add( menu2 )    //submenu of menu1
menu1.addSeparator()
