Question

I recently moved from NetBeans to Eclipse and I very much miss one great feature – whenever I use method which throws some kind of exception, NetBeans alerted me and I needed to add try-catch and NetBeans automatically generated exception type for me. Is there something similiar for Eclipse?

f.e. : Integer.parseInt(new String("foo"));

NetBeans alerts I need to catch NumberFormatException.

Eclipse doesn’t alert me at all

I am using Eclipse Java EE IDE for Web Developers, 3.5 – Galileo

Answer 1

It most certainly does. You have to hit “save” (CTRL + S) before that, of course.

Of course, you shouldn’t have declared the method to throw that exception (for example throws Exception)

Also make sure you have Project > Build automatically selected.

Important: You don’t declare or catch RuntimeException or its subclasses – these are unchecked exceptions, and for them eclipse rightly doesn’t offer any options. NumberFormatExceptions is one of these.

Try the methods of FileInputStream, for example, where IOException – a checked exception – is thrown.

(for the record – NetBeans also doesn’t do anything for Integer.parseInt(..))
