What happens if you wrap try catch in try catch block?


Asked by Brooks Brewer on Dec 13, 2021 FAQ



Since this is a terminating error, it will stop your script from continuing. To stop this error from terminating your script, wrap the command in a Try Catch block. If we wrap this error in a PowerShell Try Catch block, PowerShell will suppress the error.
Keeping this in consideration,
A try/catch block is placed around the code that might generate an exception. Code within a try/catch block is referred to as protected code. When an exception raised inside a try block, instead of terminating the program JVM stores the exception details in the exception stack and proceeds to the catch block.
Also, If no catch block is found, then the CLR displays an unhandled exception message to the user and stops execution of the program. The try block contains the guarded code that may cause the exception.
Just so,
Try...Finally can be used extensively for recovery in the face of unexpected exceptions. Only if you expect an exception and now how to deal with it should you use Try..Catch instead. Sometimes I see Try..Catch System.Exception, where the catch block just logs the exception and re-throws.
Additionally,
A throw statement can be used in a catch block to re-throw the exception that is caught by the catch statement. The following example extracts source information from an IOException exception, and then throws the exception to the parent method.
