How To Solve Java.lang.arithmeticexception / By Zero
two questions about Exceptions. Firstly, I got this message from my code... Exception in thread "main" java.lang.ArithmeticException: / by zero This error message means dividing by zero, such as by doing int a = 5 / 0; A method can throw an Exception class instance, can't it? But this is an expression. Why can an expression throw an Exception class instance ? My second question is about thread "main". What is thread java.lang.arithmeticexception divide by zero tablelayout "main"? Does "main" mean the static main method? java exception main arithmeticexception share|improve this question edited May 30 '12 at 14:00 WATTO Studios 7,206103145 asked May 30 '12 at 13:51 Akira Noguchi 1721413 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote java.lang.ArithmeticException is a type of Exception that aims to better describe what the problem actually is. There's no point just creating an Exception, as it really could be caused by anything. By generating an ArithmeticException, the user can immediately know that the problem is something to do with a calculation. An Exception can be thrown by any piece of code, including in calculations such as your example. Exception in thread "main" means that the exception is thrown by the main() method, which also happens to be the primary Thread that is running your code. share|improve this answer edited May 30 '12 at 14:02 answered May 30 '12 at 13:57 WATTO Studios 7,206103145 add a comment| up vote 1 down vote Method can throw exception class instance, isn't it? Yes they can. But this is statement. Why can statement throw exception class instance ? Exception can occur anywhere. So even statements can throw exceptions. And in case you meant why can't statements throw exceptions,well they ca

So the exception cam't be coming from here if ((behavioursPaginatedList.getFullListSize() % behavioursPaginatedList.getObjectsPerPage()) > 0) In this case, if behavioursPaginatedList.getObjectsPerPage() returns zero, then you will get a division by zero error. The fact that you are getting the exception says that division by zero is occurring, and that behavioursPaginatedList.getObjectsPerPage() is returning zero. You need to find out why that is happening. share|improve this answer answered Jan 26 '12 at 0:05 Stephen C 387k45411738 Thanks @Stephen C for your reply , I do not know how getObjectsPerPage() get zero since I use debbuger to inspect its value it has FullListSize = 13 ObjectPerPage = 4 –Sherif Omar Ja
