Deleting Part of An Array in Java to Free Memory on Heap
- by kate
I am implementing a dynamic programming algorithm for the knapsack problem in Java.  I declare the array and then initialize its size to be [number of objects][capacity of knapsack].  
When my number of objects or my capacity gets too large, I get a memory error because I run out of space on the heap.  My questions is:  If I delete rows from my double array as I go along, will Java free the memory as I delete?  Or does Java reserve that memory space for the size of the array I originally created?  If it's the latter, is there a way to manually free the memory in Java?
Thanks for your Help!
