Debugging these errors is the best option in front of us. But debugging is not an easy task, because there is no one-size-fits-all technique when it comes to debugging. That is why we are going to use our Java Stack Trace for handling these errors and exceptions. Head into the blog ...

Notice that the constructor forMyProjectFooBarExceptiontakes 2 arguments: a message and the Exception which caused it. Every Exception in Java has acausefield, and when doing acatch-and-rethrowlike this then you shouldalwaysset that to help people debug errors. A stack trace might now look som...
