Hi,

You had 3 tiny mistakes in your code:

  • It needed an extra curly bracket at the end to close the class.
  • You can't use the name "programmers" for your string since "programmers" is the name of the array.
String programmer = programmers[i];
  • You forgot to close the quotes, also you should use comma instead of semicolon to separate the quotes from the variables in your printf
System.out.printf("Hey %s, These are Famous Programmers! %n", programmer);

And here you have the complete code:

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 %s, These are Famous Programmers! %n", programmer);
    }


  }    
}
