Advantages of Exceptions
1: Separating Error-Handling Code from "Regular" Code:- Exceptions provide the means to separate the details of what to do when something out of the ordinary happens from the main logic of a program. In traditional programming, error detection, reporting, and handling often lead to confusing spaghetti code. Exceptions enable you to write the main flow of your code and to deal with the exceptional cases elsewhere.
2: Propagating Errors Up the Call Stack:- A second advantage of exceptions is the ability to propagate error reporting up the call stack of methods.
3: Grouping and Differentiating Error Types:- Because all exceptions thrown within a program are objects, the grouping or categorizing of exceptions is a natural outcome of the class hierarchy.
