how would i incorperate multi-threads in my coding to make the last section all execute at the same time(ive highlighted the last section):

/**
 * draw a balloon on to a canvas
 * then to make them fly
 * 
 * @author (chris twaits) 
 * @version (12/10/07)
 */
public class Balloons
{
    private Circle top;
    private Triangle middle;
    private Triangle bottom;
    private Circle top2;
    private Triangle middle2;
    private Triangle bottom2;
    private Circle top3;
    private Triangle middle3;
    private Triangle bottom3;

    /**
     * construct object
     */
    public void draw()
    {
        top = new Circle();
        top.changeColor("red");
        top.moveHorizontal(8);
        top.moveVertical(121);
        top.changeSize(60);
        top.makeVisible();

        middle = new Triangle();  
        middle.changeColor("green");
        middle.changeSize(-38, 55);
        middle.moveHorizontal(8);
        middle.moveVertical(247);
        middle.makeVisible();

        bottom = new Triangle();  
        bottom.changeColor("blue");
        bottom.changeSize(7, 11);
        bottom.moveHorizontal(8);

        top3 = new Circle();
        top3.changeColor("yellow");
        top3.moveHorizontal(240);

        middle3 = new Triangle();  
        middle3.changeColor("blue");
        middle3.changeSize(-38, 55);

    }    
     /**

     public void slowMoveVertical ()

    {

Actually, this should all be done in 1 thread. I'm guessing you have multiple objects on screen that you want to appear to move at the same time? You would update the positions of all the objects, and only after that should you redraw the objects. If you use double buffering on your canvas, the redraw won't flicker at all and you should see what appears to be all the objects move at the same time.

If the slowMoveVertical(int) method isn't an instant jump from X to X-50 and instead slowly increments up to that position, then you can make an additional thread but it would handle the movement for all the objects. You do not want a separate thread for each moving object, which is what I think you were trying to do.

Can you display the code for those 'move' methods?

[snitch321]

im not totally sure what you are sayin, but i thought my move method source code is shown.
my overall project goes like this:
Balloons(class)

square(class) circle(class) Triangle(class)

canvas(class)
sry if that is not clear or helps.

[Phaelax]

I do not know what any of those objects are.

slowMoveVertical(-50)

How does this work? I need to see its implementation so I know exactly what it's doing. You've basically just posted a bunch of method calls belonging to classes nobody but you knows anything about.

[snitch321]

ok dude i know your trying to help, but your speakin a little negative, im a beginner ok, im not a professional so have some patience.anyways no worrys guys, ill go else where thank you for your efforts.

Several people have asked you to show the code for slowMoveVertical(int) from the appropriate class, yet you never do - in this thread or the others you have posted about this same question. If you want to get offended at "speakin a little negative" and refused to be helped, then the problem is your own and perhaps you should go elsewhere.
