Sep 17, 2008 · The stack is the area of memory where local variables (including method parameters) are stored. When it comes to object variables, these are merely references (pointers) to the actual objects on the heap. Every time an object is instantiated, a chunk of heap memory is set aside to hold the data (state) of that object.
Feb 22, 2010 · Heap memory is essentially a large pool of memory (typically per process) from which the running program can request chunks. This is typically called dynamic allocation. It is different from the Stack, where "automatic variables" are allocated. So, for example, when you define in a C function a pointer variable, enough space to hold a memory ...
Mar 31, 2016 · I understand that this is because there is only a finite amount of memory on the stack, as opposed to the heap which has more memory. I have tried the following without much luck (does not compile): #define SIZE 262144. int *myArray[SIZE] = new int[SIZE]; And then I considered using malloc, but I was wondering if there was a more C++ like way ...
Dec 15, 2015 · In my textbook, I found this definition of a heap: a heap is a complete binary tree with the following properties: 1) the value in the root is the smallest item in the tree; 2) every subtree is a heap. But when I was watching videos about heaps, I found a totally different definition of heaps which says: In a heap the parent keys are bigger ...
Jan 4, 2013 · You can use Java Priority Queue as a Heap. Min Heap: --> to keep the min element always on top, so you can access it in O (1). Max Heap: --> to keep the max element always on top, the same order as above. Which is the same as (Integer o1, Integer o2) -> Integer.compare(o2, o1) or - Integer.compare(o1, o2) as suggested from other answers.
Oct 14, 2009 · It is possible to increase heap size allocated by the JVM by using these command line options: -Xms<size> set initial Java heap size. -Xmx<size> set maximum Java heap size. -Xss<size> set java thread stack size. In the following example, minimum heap size is set to 16mb, and the maximum to 64mb: java -Xms16m -Xmx64m ClassName. edited Oct 26 ...

if the initial heap is too small, the Java application startup becomes slow as the JVM is forced to perform garbage collection frequently until the heap has grown to a more reasonable size. For optimal startup performance you should set the initial heap size to the same as the maximum heap size. thanks.
Jul 8, 2009 · The JVM will start with memory useage at the initial heap level. If the maxheap is higher, it will grow to the maxheap size as memory requirements exceed it's current memory. So, -Xms512m -Xmx512m. JVM starts with 512 M, never resizes. -Xms64m -Xmx512m. JVM starts with 64M, grows (up to max ceiling of 512) if mem. requirements exceed 64.
