Runtime.freeMemory Call

The memory requirement for the program I am running increases with
time.

I used this call(Runtime.freeMemory) in my program but surprisingly
the amount of memory returned by this call went on increasing when I
would have expected the program to return less amount of free memory.
Any clue about this kind of behavior of this system call?

what you see is available heap space. if the vm runs out of heap it will
increase heap size.
See -Xms and -Xmx switches for vm.
