If a catch block handles multiple exceptions, you can separate them using a pipe (|) and in this case, exception parameter (ex) is final, so you can’t change it. The byte code generated by this feature is smaller and reduce code redundancy.
public class Java7MultipleExceptions { public static void main(String[] args) { try{ rethrow("abc"); }catch(FirstException | SecondException | ThirdException e){ //以下赋值将会在编译期抛出异常,因为e是final型的 //e = new Exception(); System.out.println(e.getMessage()); } } static void...

First of all you can define multiple exceptions to catch in a single block. And second of all an important aspect over the regular Java counter parts is that Camel will check in the exception hierarchy when it matches a thrown exception against the doCatch blocks. The reasons is that many ...
The catch keyword in Java is used in exception handling to catch exceptions that might be thrown in a try block. It allows the programmer to handle errors gracefully without crashing the program. The catch block follows a try block and contains code to handle the specific type of exception sp...

They can do error recovery, prompt the user to make a decision, or propagate the error up to a higher-level handler using chained exceptions, as described in the Chained Exceptions section. Catching More Than One Type of Exception with One Exception Handler In Java SE 7 and later, a ...
