Java array

public class Programmers {

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

System.out.println("Choose a programmer:");
// 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
  ...
*/
for ( int i = 0 ; i < programmers.length; i++)
{
  String [] programmer = programmers[i] ;
  System.out.printf(" Hey all of them");
}

}

}

it accepts

public class Programmers {

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

    System.out.println("Choose a programmer:");
    // 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
      ...
    */
    for(int i = 0; i < programmers.length; i++){
       System.out.println((i+1)+" "+programmers[i]);
    }
  }
}

There are other minor variants of the loop, such as:

   for(int i = 0; i < programmers.length; i++){
      int adjustedIndex = i+1;
      String programmer = programmers[i];
      System.out.println(adjustedIndex+" "+programmer);
    }

or

    for(int i = 0; i < programmers.length; i++){
      int adjustedIndex = i+1;
      String programmer = programmers[i];
      System.out.println(String.format("%x %s", adjustedIndex, programmer));
    }

In reference to your code, the variable type for programmer should be String rather than String[]. And using printf rather than println would probably require that you provide the line end.
