it says something about images, i thought that the reason might be the amount of images i put in the code to load, i removed some of them, and the program runs, what is the problem behind this? i searched some on the web, and i ended up with the VisualVM, profiling something, i know where to open that program, but i dont know how to use it to asses my java heap space problem any help please..

java.lang.OutOfMemoryError: Java heap space

first line of the error man. out of memory

Increase the heap size by using the -Xmx VM argument to an appropriate size

thank you for pointing me at the right direction again, thats what i was thinking, adjusting the heap size, but i decided to ask first, and by the way, is it because every image is loaded "STATICALLY" means that as long as the program is running, the class is loaded, all the image references is "JUST THERE"? im about to try this but.. would i minimize the outcome, by just creating instances of that class, call an instance method , load the image, and just return the only images i need?
