How To Avoid Stack Overflow In Java
up How does a “stack overflow” occur and how do you prevent it? up vote 26 down vote favorite 10 How does a stack overflow occur and what are the best ways to make sure it doesn't happen, or ways to prevent how to avoid stack overflow in recursion java one, particularly on web servers, but other examples would be interesting as well? memory stack-overflow share|improve this question edited Jul 29 at 17:46 Kapol 4,2592727 asked Aug 25 '08 at 14:49 JasonMichael 88231621 add a comment| 9 Answers 9 active oldest votes up vote 42 down vote accepted Stack A stack, in this context, is the last in, first out buffer you place data while your program runs. Last in, first out (LIFO) means that the last thing you put in is always how to prevent stack overflow in recursion 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 ar

When Does Stack (process Stack) Overflow? What Are The Remedies?

Example I'm trying to solve Project Euler problem 14 and decided to try it with a recursive algorithm. However, the program stops with a java.lang.StackOverflowError. Understandably. The algorithm indeed overflowed the stack because I tried to generate a Collatz sequence for a very large number. Solutions So I was wondering: what http://programmers.stackexchange.com/questions/194646/what-methods-are-there-to-avoid-a-stack-overflow-in-a-recursive-algorithm standard ways are there to solve a stack overflow assuming your recursive algorithm was written correctly and would always end up overflowing the stack? Two concepts that came to mind were: tail recursion iteration Are ideas (1) and (2) correct? Are there other options? Edit It would help to see some code, preferably in Java, C#, Groovy or Scala. Perhaps don't use the Project Euler problem mentioned above so it won't get spoiled for others, but take some other algorithm. Factorial maybe, or something similar. algorithms computer-science recursion tail-call share|improve this question edited Feb 5 at 18:33 Randy Marsh 1055 asked Apr 11 '13 at 10:46 Lernkurve 3541312 3 Iteration. Memoisation –James Apr 11 '13 at 10:50 2 Obviously, Memoization only works when there actually is repeated calculation. –Jörg W Mittag Apr 11 '13 at 12:06 2 also worth noting that not all language implementations can do tail recursion optimizations anyway –jk. Apr 11 '13 at 12:22 2 This would probably be better solved with corecursion than recursion. –Jörg W Mittag Apr 11 '13 at 13:31 3 If you are working from the number less than 1,000,000 and going to 1, the answer to this question involves about 500 steps to reach 1. This should not tax recursion given a small stack frame. --- If you are attempting to solve starting at 1,
ProgrammingHow can I prevent stack overflow in recursive function in C or C++ programming? How can I sanitize a user input to avoid a segmentation fault?UpdateCancelAnswer Wiki6 Answers Matthew Lai, BSc EE. https://www.quora.com/How-can-I-prevent-stack-overflow-in-recursive-function-in-C-or-C++-programming-How-can-I-sanitize-a-user-input-to-avoid-a-segmentation-fault I make robots, among other things.Written 70w agoThere is no generic way. It depends on your specific application.You have to limit recursion depth so that stack frame size * depth is less than the maximum stack size.Stack frame size is essentially the size of stack variables, and a small overhead for return address and register preservation (depending on call convention). It is especially important to stack overflow limit stack usage in deeply recursive functions. Try to move larger objects to the heap (or use standard containers, most of which are backed by the heap).1.9k Views · View UpvotesRelated QuestionsMore Answers BelowWhich is faster recursive function or normal function in C++.?How often does a recursive method written in a functional programming language suffer stack overflow?C (programming language): What is an explanation for this stack overflow in statement in C : Any function may be called recursively?How do I increase default recursion stack limit in c++?In C# programming, what two properties can be changed to prevent user input in a textbox?

Then you just take the program's stack size and divide it. Finding the stack frame size is a basic CS exercise.1.8k Views · View Upvotes Mark Miller, Programmed in C for 6 years, back in the 1990'sWritten 65w agoA general method for avoiding a stack overflow is to include what's called a "bootstrap condition" within the recursion. It's some condition that gets hit every time the function calls itself. You set the condition to something that causes the function to return when some state is reached, thereby unwinding the stack.If you have a lot of recursion, which exceeds the stack size, there may be a setting in the compiler you ca
