please please please I need some urgent help

I am writing a lift simulation program that involves a lot of animation

at run time when the program has been running for a while I get the
following error :-

Exception occurred during event dispatching:
java.lang.OutOfMemoryError
        at sun.awt.image.Image.<init>(Compiled Code)
        at sun.awt.windows.WImage.<init>(Compiled Code)
        at sun.awt.windows.WOffScreenImage.<init>(Compiled Code)
        at sun.awt.windows.WComponentPeer.createImage(Compiled Code)
        at java.awt.Component.createImage(Compiled Code)
        at elevator.update(Compiled Code)
        at sun.awt.windows.WComponentPeer.handleEvent(Compiled Code)
        at java.awt.Component.dispatchEventImpl(Compiled Code)
        at java.awt.Component.dispatchEvent(Compiled Code)
        at java.awt.EventDispatchThread.run(Compiled Code)

how can I over come this

is this because I am using the same image multiple times?

will a media Traker solve this

I would appreciate any ideas any body has

Thanks in advance

Just how many images and what sizes are you using?

The JVM only uses a very limited amount of memory by default. Try the
option -Xmx to set a higher maximum. E.g. -Xmx200m for 200 MB. (Java
1.2, I think it's just -mx for < 1.2). 

Maybe optimizing your program would help as well ;-)
