Where is the "printf" method?

Question

I have attended to a Sun TechDays lecture showing some new features of J2SDK 1.5 - one of the "hottest things" (hot for the guys with C background...) was the good old "printf" function.
I have downloaded the alpha b31 release. Where is the "printf" function? Is it scheduled to be released in Tiger?
I particularly do not like the "printf" and "scanf" functions, but "promise is debt" (literal translation from the Portuguese).
It is not difficult to write a printf method using the new variance syntax. But the scanf method poses some problems:
char *s = "1000 1.2";
int d; float f;
sscanf (s, "%d %f",  &d, &f);
String s = "1000 1.2";
StringReader sr = ...;
___ d = new ___;
___ f = new ___;
sr.scanf ("%d %f", d, f);I can't pass a "Integer" or a "Float" object because they are immutable. If I use the idiom "if you want to pass a int by reference, create a one-element array, pass the array, and get the first element" it will eternize the idiom:
int[] d = new int[1];
float[] f = new float[1];
sr.scanf ("%d %f", d, f);Maybe scanf could return an Object[]. We will have
Object[] o = sr.scanf ("%d %f");
System.out.println (o[0]); //-- the first value
System.out.println (o[1]); //-- the second valueUgly. If Java had tuples:
<d, f> = sr.scanf ("%d %f");
The "principle of minimum astonishment" rules against tuples, although they could be very useful (think the lots of JavaBeans that are created only to return two or three fields...)

Answer 1

What about:
Object[] array = new Object[2];
sr.scanf ("%d %f", array);
Integer i = (Integer) array[0];
Float f = (Float) array[0];
