I am getting OutOfMemoryError: java heap

snippets of the method:

{
// step 1: I am creating a 2 dim array
  int totalCombination = (int) Math.pow(2.0, (double) vowelCount);
  here vowelCount > 10

// step2: initializing my array
// step3: and using that array
}

My Question:

each time this method is called, that array is getting created. Is it possible that the array is not getting released .

In windows taskmanager i can see memory used by java is purely incremental. So it is not that at a point heap size is less, but memory is repetitively used and not released somehow.

Please let me know if you need more detal.

Please help to debug the error.
