I think I increased my heap size to 1 GB in NetBeans since I changed the config to look like this:
netbeans_default_options="-J-Xmx1g ......
After I restarted NetBeans, can I be sure that my app is given 1 GB now?
Is there a way to verify this?
Use this code:
// Get current size of heap in bytes
long heapSize = Runtime.getRuntime().totalMemory();
// Get maximum size of heap in bytes. The heap cannot grow beyond this size.// Any attempt will result in an OutOfMemoryException.
long heapMaxSize = Runtime.getRuntime().maxMemory();
// Get amount of free memory within the heap in bytes. This size will increase // after garbage collection and decrease as new objects are created.
long heapFreeSize = Runtime.getRuntime().freeMemory();
It was useful to me to know it.
