The abnormally large classification is divided into detection anomaly (checked exception) and non-detectable anomaly (unchecked exception). The detection exception is the exception that can be found in the compiler.
Non-detectable anomaly also includes error and Exception th

In programming, exception handling is a key and important part. The
OverviewIn general, enterprise-level applications are corresponding to complex business logic, in order to ensure the robustness of the system, it is necessary to face a variety of system business anomalies and run-time anomalies.Bad exception handling can easily cause application logic to be confusing, fragile and difficult to manage. The application is flooded with fragmented exception-handling code that
ExceptionException: An exception is an error that occurs while the Java program is running. Exception Origin: The problem is also a real life of a specific transaction, can also be described in the form of Java classes, and encapsulated into objects. In fact, Java is a description of the abnormal situation after the object. Throwable|--error Serious problems that we do not deal with. |--
Exception handling is a very important aspect of program design, but also a great difficulty in programming, starting from C, you may already know how to use if...else ... To control the exception, may be spontaneous, however, this control is extremely painful, the same exception or error if multiple places appear, then you have to do the same in every place, fee
Abstract
People are not sages. Code is written by humans, and of course it cannot be error-free. We can only expect that the code is more robust and not perfect. What we can do more is how to recover from errors or find alternative solutions. CLR provides an exception handling mechanism, which not only allows people to handle exceptions more elegantly when code errors occur, but also throws exceptions when necessary. So how can we more standardize the
Summary: catch (Exception ex) is the class Std:exception;catch (...) captured in all standard library definitions. is to catch all the exceptions.
1. Introduction
Exceptions are a way of running time error handling provided by the language. When it comes to error handling, you probably already have a lot of experience, even if you don't mention the exception, but in order to see the benefits of the

Item M14: Careful use of exception specifications (Exception specifications)There is no doubt that exception specifications are a compelling feature. It makes the code easier to understand because it clearly describes what kind of exceptions a function can throw. But it's not just an interesting comment. The compiler can sometimes detect inconsistencies in the
Comparison between C ++ and Windows structure exceptions
Windows structure exceptions have the following features:
1. It uses the _ try, _ partition T, _ finally, and _ leave keywords and RaiseException APIS;
2. It is supported by Windows, so it is not suitable for other operating systems
3. It does not parse C ++ objects
Note: If a C ++ object exists in a function with a Windows structure exception, the compiler will issue
