java looping stuck

i dont what i suppose to code

public class Programmers {

  public void printMenu() {
    String[] programmers = {
            "Yukihiro Matsumoto",
            "David Nolen",
            "Grace Hopper",
            "Linus Torvalds",
            "You"
    };
    for (int i = 0; i < programmers.length; i++)
    {
    System.out.printf("Choose a programmer:" , programmers[i]);
}
    // TODO: Print out a menu by looping through the programmers array.
    /*
      The menu should be in the form of (each on a line of its own, starting with 1):
      1. Yukihiro Matsumoto
      2. David Nolen
      ...
    */


  }

first of all, you probably want to bring "choose a programmer" outside the loop so it only prints once at the top.

then inside the loop you could use:

System.out.println( (i+1) + ". " + programmers[i]

(it's i+1 for the number out front because arrays start at zero)
