Comments on: Ten Little Soul Crushing Features of Java http://blog.darevay.com/2009/04/ten-little-soul-crushing-features-of-java/ You know, software and some other stuff like maybe guitar or something Tue, 15 Jun 2010 15:31:37 +0000 http://wordpress.org/?v=2.9.2 hourly 1 By: Dario http://blog.darevay.com/2009/04/ten-little-soul-crushing-features-of-java/comment-page-1/#comment-1837 Dario Wed, 22 Jul 2009 15:43:18 +0000 http://blog.darevay.com/?p=205#comment-1837 IllegalArgumentException is to be thrown when argument is illegal or inappropiate, and it's a RuntimeException (About RuntimeException, since every method can throw it, none is required to tell, so it's easy to miss that or any of its subclasses) MalformedURLException is more strict, specifically it hasn't a recognizable protocol or the url string couldn't be parsed. It's a IOException subclass, no a RuntimeException one, so it has to be declared and thus it won't jump by surprise. Beside RuntimeException family (like NullPointer, ClassCast, IndexOutOfBounds...), MalformedURLException seems full of sense to me...

String s = String.fromFile(“test.txt”);
or something like that.

Isn't that what String.concat(String) is for? 10. InputStream and Reader are streaming interfaces, which means that they can have more content than you can fit in an array. It sounds like you're talking about file based input stream or readers, in which case you can do this (provided your file length is smaller than 2GB): method(File file) { FileInputStream fis = new FileInputStream(file); byte[] bytes = new byte[(int)file.length()); fis.read(bytes); } 1.

I have only found myself cussing late at night over #2,3,4,6,78,9, and 10. Pretty amazing list, although a perhaps a little exaggerated.
