Who wants some easy Duke Points

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);

}

}
