Java Java Arrays Iteration Looping Like These Programmers

I'm having trouble to print out all the String variable

can someone give me some advice about this?

public class Programmers {

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

     int[] programmer = {1,2,3,4,5};
    for (int i = 0; i < programmers.length; i++) {
    System.out.printf("Choose a programmer: %s %n", programmers);

    // 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

Hey, What you are trying to do is print the following:

  1. Yukihiro Matsumoto
  2. David Nolen
  3. Grace Hopper
  4. Linus Torvalds
  5. You

The programmers is an array of length 5 but arrays in java are zero indexed arrays ( meaning the first index is 0). when looping through the array, you should start at index 0 and end when the i < programmers.length. (so what you wrote down is correct) After you have that, inside the for loop you should have the code below.

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

the i+1 will help print the numbers 1-5. and programmers[i] will access all the elements in the array.

Hope this helps.
