up Design patterns: exception / error handling up vote 25 down vote favorite 19 Is there any resource (web or book) describing exception handling / error handling design patterns? There is a lot of literature on how to write clean code, and there are a lot of books covering design patterns. I have, however, never seen any design pattern covering the issue of java error handling examples where and how best to handle errors and how best to propagate an error appearing in a low-level function up the levels of abstraction. design-patterns exception-handling share|improve this question asked Mar 21 '13 at 8:31 JohnB 6,75411645 add a comment| 3 Answers 3 active oldest votes up vote 30 down vote accepted These patterns and best practices are often bound to a specific platform/language, so they are the first place to look for them. Exception patterns wiki is a general patterns resource.

However I think it is worth it to have two exception classes inheriting from RuntimeException instead of just one. The idea is to use one class to represent general faults (NPE, etc.) that can't be handled in place, and my strategy is to catch and log them in a single fault barrier so developers/devOps can troubleshoot them. These exceptions should be wrapped and passed back hiding some implementation details to the users of the API? The other class will represent the exceptions that should be passed back to the users of the API since they are expecting them and know how to handle them (say specific exceptional conditions that are part a web services API). Any drawbacks of using these two exception classes or is it better to use just one class for everything? Thanks. java exception-handling share|improve this question asked Nov 20 '14 at 14:49 dabd 1313 add a comment| 4 Answe

In this post, I am covering some well-known and some little known practices which you must consider while handling exceptions in your next java programming assignment. Follow this link to read more about exception handling in java.Table of Contents error handling Type of exceptions User defined custom exceptions Best practices you must consider and follow Never swallow the exception in catch block Declare the specific checked exceptions that your method can throw Do not catch the Exception class rather catch specific sub classes Never catch Throwable class Always correctly wrap the exceptions in custom exceptions so that java error handling stack trace is not lost Either log the exception or throw it but never do the both Never throw any exception from finally block Always catch only those exceptions that you can actually handle Don't use printStackTrace() statement or similar methods Use finally blocks instead of catch blocks if you are not going to handle exception Remember "Throw early catch late" principle Always clean up after handling the exception Throw only relevant exception from a method Never use exceptions for flow control in your program Validate user input to catch adverse conditions very early in request processing Always include all information about an exception in single log message Pass all relevant information to exceptions to make them informative as much as possible Always terminate the thread which it is interrupted Use template methods for repeated try-catch Document all exceptions in your application in javadocBefore we dive into deep concepts of exception handling best practices, lets start with one of the most important concepts which is
