当栈空间满了,Java运行时会抛出 java.lang.StackOverFlowError ,然而堆空间满了,抛出的是 java.lang.OutOfMemoryError: Java Heap Space 错误 栈空间相比较于堆空间是非常小的,又因为栈中使用最简单的先进后出(LIFO)原则,它是远远快于堆的。
Note:The limited size of the stack is a constraint, but it also acts as a protection mechanism. The system notices a stack overflow and a program terminates. In contrast, a memory leak in the heap might go unnoticed for a long time, potentially until it consumes all available system memory...
The stack and heap here is a kind of memory, not data structure. (1) the way for memory allocation stack memory was allocated by the compiler automatically, while the heap was allocated manually. (2) the limitation of size stack memory was limited by system, usually 2 megabytes. But you ...
stack memory will never become fragment but heap will be because blocks of memory are first allocated and then freed. stack accesses local variables only and heap allows you to access variables globally. stack variables can’t be resized but heap can stack allocation and deallocation are done by...
This makes it really simple to keep track of the stack, freeing a block from the stack is nothing more than adjusting one pointer. Variables allocated on the heap have their memory allocated at run time and accessing this memory is a bit slower, but the heap size is only limited by the...
In transitive terms the difference between stack and heap is thatstackis to deliberately distort the composition of (an assembly, committee, etc.) whileheapis to supply in great quantity. stack English (wikipedia stack) Noun (en noun)
