Thanks for ur reply ..
I tried that ...i guess my question would be how to INCREASE the Total
Memory or free memory ...even after using the garbage collection method the
freee memory available is not sufficeint enough to do what my program
intends to do ..again remember i can't use the -mx option as the java
command is no where used
Also what units are the following # s in ?bytes?
Total Memory is 2199544
Initial Free Memory is 1174592
After Garbage Collection, Free Memory is 1295048
Please help
Thanks

<grin>
welcome to the world of java. pointers need not apply ...
</grin>
use of 'new' verb will allocate the required memory.
but if you need feedback on memory or resources remaining, use the following
example:
//
// memory usage example below ...
//
Runtime r = Runtime.getRuntime ( );
long totalMem = r.totalMemory ( );
System.out.println ( "Total Memory is " + totalMem + "\n" );
long freeMem = r.freeMemory ( );
System.out.println ( "Initial Free Memory is " + freeMem + "\n" );
/*
*
* do some java memory stuff here ...
*
*/
freeMem = r.freeMemory ( );
System.out.println ( "After Some Java Memory Stuff, Free Memory is " +
freeMem + "\n" );
r.gc ( ); // do some garbage collection ...
freeMem = r.freeMemory ( );
System.out.println ( "After Garbage Collection, Free Memory is " + freeMem +
"\n" );
//
// end of example ...
//

You can get an OutOfMemory error because you are trying to allocate more
memory
than the VM currently has available. Of course, the VM is not smart enough
to
garbage collect and then try it again. This is a very common thing that
happens
with large single allocations. I use the following:
try {
// huge allocation
}catch( OutOfMemoryError e ){
Runtime.getRuntime().gc();
Runtime.getRuntime().runFinalization();
// try huge allocation again
}
If there really is enough memory, this will work. We have a large imaging
system we have written, and have this code peppered a lot of places.
