Proposed Java 7 Feature: Multi-Catch Statements
How many times have you written code where you have something along the lines of:
try { do something interesting ... }
catch (X1 e1) { close(); }
catch (X2 e2) { close(); }
catch (X3 e3) { cleanup(); }
It is cumbersome to have to catch X1 and X2 separately even though they perform the same action if an Exception is raised. Wouldn’t it be nice if there was a way to catch both X1 and X2 with one single catch block?
Enter the Java 7 proposal for Multi-Catch statements. If/when this proposal makes it in to the language, it would eliminate the need to have a catch statement for each Exception. It facilities a mechanism to catch multiple Exceptions, and then perform the same action on them eliminating the need to have one catch per Exception thrown.
try { do something interesting ... }
catch (X1, X2 e1) { close(); }
catch (X3 e ) { cleanup(); }
Now isn’t this code much cleaner? Let’s hope it makes it in to the next version of Java.
