public class Slider extends JFrame{
	private JPanel cjp = new JPanel();
	private JPanel sjp = new JPanel();

	private JLabel gjl = new JLabel("Green",SwingConstants.RIGHT);
	private JLabel bjl = new JLabel("Blue", SwingConstants.RIGHT);

	private JSlider rjs = new JSlider(0,100,100);
	private JSlider gjs = new JSlider(0,100, 70);
	private JSlider bjs = new JSlider(0,100, 70);

	private JTextField rjtf = new JTextField(10);
	private JTextField gjtf = new JTextField(10);
	private JTextField bjtf = new JTextField(10);

	private float red, green, blue;

		cp.add("Center",cjp);

		rjs.addChangeListener(new ChangeListener(){
			public void stateChanged(ChangeEvent ch){
				red   = 0.01F * rjs.getValue();
