Question

this is copied directly from the Sun's Java Tutorial (see link):
http://java.sun.com/docs/books/tutorial/essential/io/formatting.html
is it a typo?
public class Root2 {
     public static void main(String[] args) {
          int i = 2;
          double r = Math.sqrt(i);
          System.out.format("The square root of %d is %f.%n", i,r);
the line starting with System.out..... gives me the error:
The method format(String, Object[]) in the type PrintStream is not applicable for the arguments
(String, int, double)
I changed things around and got it to work as follows:
public class Root2 {
     public static void main(String[] args) {
          int i = 7;
          double r = Math.sqrt(i);
          Number[] n = {Integer.valueOf(i),Double.valueOf(r)};
          System.out.format("The square root of %d is %f.%n", n);
}

Answer 1

actually - I started using java 1.6.0_02 and Ialso
tried 1.5.0_11 - I'm using eclipse 3.2.2Check your compiler settings.as kajbj said, check thecompiler settings, chances are they are set to compile to a compliance level of 1.4 (Window -> Java -> Compiler -> Compiler compliance level)
