Last in, first out (LIFO) means that the last thing you put in is always the first thing you get

back out - if you push 2 items on the stack, 'A' and then 'B', then the first thing you pop off the stack will be 'B', and the next thing is 'A'. When you call a function in your code, the next instruction after the function call is stored on the stack, and any storage space that might be overwritten by the function call. The function you call might use up more stack for its own local variables. When it's done, it frees up the local variable stack space it used, then returns to the previous function. Stack overflow A stack overflow is when you've used up more memory for the stack than your program was supposed to use. In embedded systems you might only have 256 bytes for the stack, and if each function takes up 32 bytes then you can only have function calls 8 deep - function 1 calls function 2 who calls function 3 who calls function 4 .... who calls function 8 who calls function 9, but function 9 overwrites memory outside the stack. This might overwrite memory, code, etc. Many programmers make this mistake by calling function A that then calls function B, that then calls function C, that then calls function A. It might work most of the time, but just once the wrong input will cause it to go in that circle forever until the computer recognizes that the stack is overblown. Recursive functions are also a cause for this, but if you're writing re

[duplicate] up vote 205 down vote favorite 37 This question already has an answer here: What http://stackoverflow.com/questions/26158/how-does-a-stack-overflow-occur-and-how-do-you-prevent-it is a StackOverflowError? 11 answers I've looked everywhere and can't find a solid answer. According to the documentation, Java throws a java.lang.StackOverflowError error under the following circumstance: Thrown when a stack overflow occurs because an application recurses too deeply. But this raises two questions: Aren't there other ways for a stack overflow to occur, not only through recursion? Does the StackOverflowError happen before the JVM actually overflows the stack or after? To elaborate on the http://stackoverflow.com/questions/22182669/what-actually-causes-a-stack-overflow-error second question: When Java throws the StackOverflowError, can you safely assume that the stack did not write into the heap? If you shrink the size of the stack or heap in a try/catch on a function that throws a stack overflow, can you continue working? Is this documented anywhere? Answers I am not looking for: A StackOverflow happens because of bad recursion. A StackOverflow happens when the heap meets the stack. java jvm stack-overflow share|improve this question edited Mar 4 '14 at 21:54 hichris123 6,551113257 asked Mar 4 '14 at 20:46 retrohacker 1,66731025 marked as duplicate by Jarrod Robersonjava Users with the java badge can single-handedly close java questions as duplicates and reopen them as needed.

That makes it unlikely to produce a stack overflow without recursion. –nosid Mar 4 '14 at 20:49 1 You could produce a gigantic chain of method calls which would cause a SO (like method a calling b, b calling c, c
usage occurs on the call stack, which is where information is stored relating http://www.computerhope.com/jargon/s/stacover.htm to the active subroutines in the program. The call stack has a limited amount of memory available to it. Its size is determined by the programming language, the architecture, whether multi-threading is available on the CPU, and how much memory is available. Typically, when a stack overflow error occurs, the stack overflow program crashes and can either freeze or close the program. Any unsaved data or work is lost. The stack overflow error is often caused by either an infinite loop in the programming, or the creation of variables that are too large for the size of the call stack. The stack overflow stack overflow error problem is not as prevalent on the newer operating systems, however, because of the small footprint on mobile devices it can become challenging. If your operating system on your mobile device is giving you a stack overflow error you may have too many apps running, a virus is using stack space, or your device has bad hardware. Check your app usage and virus protection and run a memory diagnostic app on your mobile device to see if this helps clear up your error. Related pages Stack overflow system halted error.
