Except for a few examples, I don't see a section on the "Scala way" of doing IO. For example, if I want to process files and folders, should I just use Java classes? Or does Scala provide a more convenient way?
And speaking of convenience, is there any way to use C-style printf statements in Scala, as can be done in more recent versions of Java, e.g.
System.printf("%4d: %s\n", lineNum, line);
I've looked at Console.printf, but it's not a C-style print; I haven't yet figure out how to simulate this using Java's MessageFormat syntax.
You may know this already, but varargs in Java are just syntactic sugar for arrays. So the method signature <code>public Object doSomething(Integer... ints)</code> compiles to be the equivalent of <code>public Object doSomething(Integer[] ints)</code> Given that, I would imagine you could call varargs methods in Java classes just as you would ones taking arrays.

Given that, I would imagine you could call varargs methods from Scala just as you would ones that take arrays as parameters.
