Its asking me to do this exercise using a for loop but i'm having trouble, any help?

The commented section is what i need to do but i can't seem to do it.

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:");
    // 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 program = programmers[i];

     System.out.printf("#%d. %s %n", 
                       program);

    }  




    }








    // 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
      ...
    */


  }
}

Good Afternoon Ryan,

You would use %d if you were printing a decimal. You are only printing people's names, so each name is a String.

The hash symbol is used in formatting the output of your numbers like shown below. Since your code has no numbers, it should not have any hash symbols.

customFormat("###,###.###", 123456.789);

Change this one line of code and your program should work.

console.printf("%s %n", program);

I hope this was helpful to you.

Mark
