I mean how VM manages to throw an exception without being previously killed by the OS? java divide-by-zero share|improve java divide by zero exception handling this question asked Jan 21 '14 at 21:27 mrpyo 1,01311330 marked as duplicate by Raedwald, Eric Leschinski, Kevin Panko, Lego Stormtroopr, iandotkelly Jan 22 '14 at 2:43 This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question. What do you mean by "previously killed"? –Oliver Charlesworth Jan 21 '14 at 21:29 One word: Zombies!! –Hot Licks Jan 21 '14 at 21:29 1 The OS won't kill the VM for a divide-by-zero. The VM will terminate if such an exception is not catched. –Stefano Sanfilippo Jan 21 '14 at 21:30 1 Division by zero is caught at hardware level and results in interrupt being called with usually leads OS to stopping the process (I'm asking how it is caught internally in VM implementation not language itself)... –mrpyo Jan 21 '14 at 21:32 2 @StefanoSanfilippo yeah the OS doesn't kill anything but the VM commits suicide ;-) –ITroubs Jan 21 '14 at 21:33 | show 7 more comments 4 Answers 4 active oldest votes up vote 30 down vote accepted In an Unix environment, in which division-by-zero is signalled via
