Both exception wrapping and rethrowing are essential techniques for effective Java exception handling. Wrapping allows for richer error information while rethrowing can maintain control over error propagation.

In order to prevent such a change from propagating to higher layers, one can wrap such low level Exceptions in a generic "data exception" wrapper, designed exclusively to protect the higher layers from such changes.

Aug 18, 2018 · How about wrapping it in an interface like this: public static void safeExecution(Wrapper w) { try { w.codeThatThrows(); } catch (Exception e) { // your error handling. public static void example() { safeExecution(() -> { throw new Exception(); }); // Or the old-fashioned way: safeExecution(new Wrapper() { @Override.
