How do I print a formatted number?

I feel a bit stupid about this, but I haven't figured out how to printed a formatted number to the console in Java. I was hoping for a "printf" or something like it. Here is a sample of what I'd like to do:

public class CtoF {
  public static void main(String[] args) {
    for (double c=34; c<44; c+=.1) {
      double f= c * 1.8 + 32;
      System.out.println(c + "C = " + f + "F");
    }
  }
}

which prints out an accurate but useless table of numbers with 15 digits of accuracy. How can I make it print out only one or two digits?
Thanks in advance.

Wouldn't it be neat if there was an interface called NumberFormat that would have implementations to format numbers?

Enjoy!

Thomas, you are the man. Not only will that do what I want, it will do it in my localization (Spain) which means numbers like "32,5". Thanks very much.
