Java handle division by zero? [duplicate] up vote 16 down vote favorite 1 This question already has an answer here: In java, “5/0” statement doesn't fire SIGFPE signal on my Linux machine, why? 6 answers Does it simply check if divisor is different from zero every time there is division done (even in JIT-ed code)? I mean how VM manages to throw an exception division by zero error in access report without being previously killed by the OS? java divide-by-zero share|improve 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

I expected to have to add some sort of checking / exception handling in case oldNum is 0. However, when I did a test run with values of 0.0 for both oldNum and newNum, execution continued as if nothing had happened and http://stackoverflow.com/questions/2381544/why-doesnt-java-throw-an-exception-when-dividing-by-0-0 no error was thrown. Running this code with ints would definitely cause an arithmetic division-by-zero exception. Why does Java ignore it when it comes to doubles? java types integer double divide-by-zero share|improve this question edited Oct 1 '12 at 9:46 Aziz Shaikh 11.5k73753 asked Mar 4 '10 at 17:57 froadie 24k46117190 2 Good question - the inconsistency between integer and double behavior adds confusion and hassle. –Steve B. Mar 4 '10 at 18:09 1 possible duplicate of Why does division by zero with floating point (or double precision) numbers not throw java.lang.ArithmeticException: / by zero in Java –Raedwald Jan 21 '14 at 21:35 1 @Raedwald - considering that this question was posted 2 1/2 years before the one you linked, I would say that question is a (possible) duplicate of this one :) –froadie Jan 22 '14 at 10:24 add a comment| 4 Answers 4 active oldest votes up vote 30 down vote accepted The result of division by zero is, mathematically speaking, undefined, which can be expressed with a float/double (as NaN - not a number), it isn't, however, wrong in any fundamental sense. As an integer must hold a specific numerical value, an error must be thrown on division by zero when dealing with them. share|

below is a code snippet which will demonstrate an exception handling in Java with Divide by zero error. public class MainClass { public static void main(String args[]) { int urAns, urDiv; try { urDiv = 0; urAns = 25 / urDiv; System.out.println("Do you really think this will print out? No! It won't!"); } catch (ArithmeticException e) { System.out.println("Division by zero not Possible!"); } System.out.println("This will print out after Exception Handling"); } } 🙂 More Similar Posts Using of CCWaves in iPhoneHow to handle configuration change in an activity using…Reading webpage contents as a string in Windows Phone 7.How to read a serialized object from a file in the raw…Detect iPad or iPhone or Android in Corona SDK?How to check whether SDCARD in mounted in android?Handling Multiple Instances of a Widget in Android and…How to open browser from android cocos2D Application?How to load a spinner with values from SQlite Database in…How to set a Bitmap Image as Source of an image in Windows…Serialization in Android - A Simple example.How to upload files to server using the new FileUpload…Switch Images in ANDROID.How to check different Network status in Android?How to Convert a string to date in JAVA ?How to take screenshot of application and store it in…How to Customize "Force Close" Dialog in…How to upload an image from Android device to server?…What is a Memory Heap Size in android? and how can use…Parsing an XML from Online in AndroidHow to encrypt and decrypt a file using "AES"…How to Download a PDF File and open it in Android using an…How to delete a contact in android?Java Applet MouseEventsHow to read and write files to SDCARD and application… Category: Java Tags: Code Snippet, Divide By Zero, Exception Handling In Java, Java Class, Java Example, Main String, println, String Args, Urans Post navigation ← Simple String
