polling

Aleks

I've been working on a Javelin project that requires polling a flash memory until it stumbles across a change in the data. However I keep running into a out of memory error. I was wondering if anyone could supply me with a javelin polling program that won't render the out of memory error?

If you are using System.out.print("some text" + number),
or in general add strings or use the new keyword in a loop, you will keep
getting those errors.

Post your program so we can see what causes the error.

From my experience when i get an OutOfMemory error i usually find something like this in my code

do{

· String newStringObject = someObject.toString();

}while(!someObjectArray.isEmpty());

what happens is that each time there is a loop it creates a whole new instance of the variable, which sucks up memory.· An easy fix for the example above would be something like:

String theVariable = "";
do{
· theVariable = someObject.toString();
· //do stuff with theVariable
}while(!someObjectArray.isEmpty());

this way it uses the same variable over and over again.

Hope this helps, if not it could be a good hint.

ok well here's my main program, as well as an additional folder of library files.

Ok so I found the problem. It seems that when anything is declared static it becomes a registered variable, not prone to change. So when I went through and declared my library files, each subroutine within them was declared static. This poses a problem in that every time the subroutine is called it recreates the used variables. Obviously thats a problem.
