How come Java's Integer class does not have compare() method?

Question

Double has Double.compare for comparing two double primitives. Why doesn't Integer have one?

I understand it's some trivial amount of code to write, but asking out of curiosity.

Edit: I realize both Integer and Double have compareTo. But using compareTo requires boxing the int primitive in an Integer object, which has a pretty high cost. Also, inta > intb is not the same as compare(inta, intb), as the latter returns +1, 0, or -1, while the former is true/false ....

It was a oversight that Java 7 will resolve

http://download.oracle.com/javase/7/docs/api/java/lang/Integer.html#compare%28int,%20int%29

public static int compare(int x, int y)

Compares two int values numerically. The value returned is identical to what would be returned by:

Integer.valueOf(x).compareTo(Integer.valueOf(y))

Parameters: x - the first int to compare y - the second int to compare Returns: the value 0 if x == y; a value less than 0 if x < y; and a value greater than 0 if x > y Since: 1.7
