Parsing A Phone Number?

In the assignment, I'm asking the user to put in a 10 digit phone number (numbers only, no dashes or parenthesis), and the program spits out the phone number WITH the parenthesis and dashes like this: System.out.printf( "(%03d) %03d-%04d", part1, part2, part3);

import java.util.*;
public class C1Phone {
public static void main(String [] args) {
Scanner in = new Scanner (System.in);
