Cognitive Complexity is a measure of how hard the control flow of a method is to understand. Methods with high Cognitive Complexity will be difficult to maintain.

Throwable is the superclass of all errors and exceptions in Java. Error is the superclass of all errors, which are not meant to be caught by applications.

Catching either Throwable or Error will also catch OutOfMemoryError and InternalError, from which an application should not attempt to recover.

Noncompliant Code Example

try { /* ... */ } catch (Throwable t) { /* ... */ }
try { /* ... */ } catch (Error e) { /* ... */ }

Compliant Solution

try { /* ... */ } catch (RuntimeException e) { /* ... */ }
try { /* ... */ } catch (MyException e) { /* ... */ }

• MITRE, CWE-396 - Declaration of Catch for Generic Exception
• C++ Core Guidelines E.14 - Use purpose-designed user-defined types as exceptions (not built-in types)
