Catching All Exceptions: Why It's Generally a Mistake
Why avoid using catch(Exception) in your code?
While it may seem convenient to handle all exceptions with a single catch(Exception) block, this practice is generally discouraged for several reasons.
1. Lack of Proper Exception Handling
By catching all exceptions, you indicate that your code can handle any type of exception that may occur. However, this is unrealistic in practice. It's impossible to anticipate and handle every conceivable exception in your code.
2. Masking Exceptions for Upper-Level Code
When an exception is thrown and caught by a catch(Exception) block, it may prevent upper-level code in the stack from handling the exception appropriately. This can result in unhandled exceptions and potentially unpredictable behavior in your application.
3. Best Practice: Catching Specific Exceptions
Instead of catching all exceptions, it's better practice to catch specific exception types that your code is equipped to handle. This approach allows you to provide targeted exception handling and avoid the pitfalls associated with catching all exceptions.
