Getting exception handling right can save you hours (or even days) of troubleshooting. Unexpected production issues can ruin your dinner and weekend plans. They can even affect your reputation if not resolved quickly. Having a clear policy on how to manage exceptions will save you time diagnosing, reproducing Wholesale Malik Hooker Jersey , and correcting issues. Here are 6 tips to improve your exception handling.

An exception (or exceptional event) is a problem that arises during the execution of a program. When an Exception occurs the normal flow of the program is disrupted and the programApplication terminates abnormally, which is not recommended, therefore, these exceptions are to be handled.
An exception can occur for many different reasons. Following are some scenarios where an exception occurs.
• A user has entered an invalid data.
• A file that needs to be opened cannot be found.
• A network connection has been lost in the middle of communications or the JVM has run out of memory.
Some of these exceptions are caused by user error Wholesale T.Y. Hilton Jersey , others by programmer error, and others by physical resources that have failed in some manner.
Based on these, we have three categories of Exceptions. You need to understand them to know how exception handling works in Java programming.
• Checked exceptions − A checked exception is an exception that occurs at the compile time, these are also called as compile time exceptions. These exceptions cannot simply be ignored at the time of compilation Wholesale Andrew Luck Jersey , the programmer should take care of (handle) these exceptions.


1. Use a single, system-wide exception class
Instead of creating separate classes for each exception type, create just one. And make it extend RuntimeException. This will reduce your class count and remove the need to declare exceptions you aren’t going to handle anyway.
I know what you’re thinking: How will I tell exceptions apart if they’re all the same type? And how will I track type-specific properties? Read on!
2. Use enums for error codes
Most of us were trained to put the cause of an exception into its message. This is fine when reviewing log files (ugh), but it does have drawbacks:
1. Messages can’t be translated (unless you’re Google).
2. Messages can’t be easily mapped to user-friendly text.
3. Messages can’t be inspected programmatically.
Putting info in the message also leaves the wording up to each developer Wholesale Khari Willis Jersey , which can lead to different phrases for the same failure.

A better approach is to use enums to indicate the exception’s type. Create one enum for each category of errors (payments, authentication, etc.). Make the enums implement an ErrorCode interface and reference it as a field in the exception.
When throwing exceptions, simply pass in the appropriate enum.

Now when you need to test for a specific case Wholesale Bobby Okereke Jersey , just compare the exception’s code with the enum.
3. Add error numbers to enums
In some cases a numerical error code can be associated with each exception. HTTP responses for example. For those cases, add a getNumber method to the ErrorCode interface and implement it in ea.
