1. If we want to handle custom exceptions, we can use@RestControllerAdvice||@ControllerAdviceconfigure@ExceptionHandlerto use. 2. If we implementResponseEntityExceptionHandlerto handle exceptions, then the default exception response result is empty. If we want to not be empty, we need to handle it...
Definition: Anexceptionis an event, which occurs during the execution of a program, that disrupts the normal flow of the program's instructions. the checked exception 比如,java.io.FileNotFoundException the error 比如,java.io.IOError the runtime exception 比如,NullPointerException error和runtime e...
Exception handlingis the process of responding to the occurrence, during computation, of exceptions – anomalous or exceptional conditions requiring special processing – often changing the normal flow of program execution. It is provided by specialized programming language constructs, computer hardware mecha...
Errors- Error is not Exception at all, but problems that arise beyond the control of user of the program, they are invariably ignored in your code and the compiler as well, because you can rarely do anything, for example, an stack overflow occurs, an error will arise. ...

In previous article (Basics of Exception handlings in java), we were discussed that, we can implement exception-handling in your program by using the following five keywords:1) tryThe try block contains a series of program statements within which an exception might occur. A try block is ...
Java exception handling with stack traces, exception chaining, try-with-resources, final re-throw, and StackWalker.
Anexception handleris a sequence of code that handles an exception. It interrogates the context—meaning that it reads values saved from variables that were in scope at the time the exception occurred—then uses what it learns to restore the Java program to a flow of normal behavior. For exa...
