Exception in thread "main" java.lang.StackOverflowError Recursion

Question

screenshot for problem screenshot for vm option

I am trying to run my program but it's throwing exception (as in screenshot), I searched for it and found it happen's because programs has too many recursive calls and I should increase stack size by setting Xss to be 1mb through,

Help -> edit custom vm option when i open it it show a message that vm option not created and i should creat by press on ok so it created but i can't find Xss parameter as screenshot show

I tried changing Xms and Xmx values in VMOptions

Note : i run this this algorithm on graph that has more than 800000 node so the recursion is finite but happens too much.

try debugging your program, and find out why it is going in infinite recursion! — dhanu10896, Feb 03 '19 at 10:12
it doesn't have infinite recursion, i run this algorithm on graph that has more than 800000 nodes, so the recursion is finite but happen too much — Karim Ata, Feb 03 '19 at 10:23
can you write your code iteratively rather than using recursion! — dhanu10896, Feb 03 '19 at 10:37
i think i should increase the depth for recursion but i don'tt know how — Karim Ata, Feb 03 '19 at 10:39
i implement Kosaraju's two path algorithm and i can't be coded as loop — Karim Ata, Feb 03 '19 at 10:41
probably this article will help you in that : https://www.geeksforgeeks.org/strongly-connected-components/ — dhanu10896, Feb 03 '19 at 10:44
no this article doesn't help me it explains the algorithm and my algorithm work good on test cases — Karim Ata, Feb 03 '19 at 10:46
my implementation as coursera course instructions with recursion — Karim Ata, Feb 03 '19 at 10:47
probably you should post question on Coursera's Q/A forum for your course, regarding this particular problem — dhanu10896, Feb 03 '19 at 10:50

Add, -Xss4096k option in vmoption file,This will increase stack size to 4mb. Save it and restart ide. For more information check, How to increase the Java stack size?

np! if above approach does not solve issue, do check with your course community, Coursera communities are very active :) – dhanu10896 Feb 03 '19 at 11:25
