import java.awt.event.*;

public class Colors extends Canvas

{

            transient private Color color;

            private boolean rectangular;

            public Colors()

            {

                        addMouseListener(new MouseAdapter()

                        {

                                    public void mousePressed(MouseEvent me)

                                    {

                                                change();

                                    }

                        });

                        setSize(200,100);

                        rectangular=false;

                        change();

            }

            public boolean getRectangular()

            {

                        return rectangular;

            }

            public void setRectangular(boolean flag)

            {

                        this.rectangular=flag;

                        repaint();

            }

            public void change()

            {

                        color=randomColor();

                        repaint();

            }

            public Color randomColor()

            {

                        int r=(int)(255*Math.random());

                        int g=(int)(255*Math.random());

                        int b=(int)(255*Math.random());

                        return(new Color(r,g,b));

            }
