In the printMenu method of the Programmers.java class, I'd like to print a menu showing off some famous programmers. Fol

mmm do not know what i did wrong

Programmers.java 
public class Programmers {

  public void printMenu() {
    String[] programmers = {
            "Yukihiro Matsumoto",
            "David Nolen",
            "Grace Hopper",
            "Linus Torvalds",
            "You"
    };

    System.out.println("Choose a programmer:");
    for(int i=0; i<programmers.length;i++){
      System.out.printf(" %d. %s%n ",i+1,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
      ...
    */




  }

Hi there! There is nothing wrong with your code, these challenges are EXTREMELY PICKY sometimes.. You just need to remove the spaces in your printf statement (before %d and after %n) like such:

   for(int i=0; i<programmers.length;i++){
      System.out.printf("%d. %s%n",i+1,programmers[i]); //On this Line, remove space before %d and after %n
    }

Take care and happy coding!

Spoiler Alert!!

public class Programmers {

  public void printMenu() {
    String[] programmers = {
            "Yukihiro Matsumoto",
            "David Nolen",
            "Grace Hopper",
            "Linus Torvalds",
            "You"
    };

    System.out.println("Choose a programmer:");
    for(int i = 0; i < programmers.length; i++){
      System.out.printf("%d. %s %n", i + 1, 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
      ...
    */
