Exception classification help use understand what exactly is the issue at hand easily even before we see the description. It is a first sigth informer to the developer to understand the issue. For example if you are getting a NullPointerException / ArithemeticException and if you just say “Exception occured” can we understand anything? without a detailed explanation. So its a means to categorize the error but ofcourse a more details explanation is given by the error description by developer who has coded.
