3,752 Pointshow to make a for loop with numbered list? Using un-enhanced for loop for this excercise.
Im not understanding the errors I'm getting. Also I'm tying to make a list but it won't work.
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.printf("%d. %s %n", i+1, programmer);
}
}
}

- there's a stray semicolon between the for clauses and the open brace of the code block
- the printf referrs to programmer, but nothing by that name has been defined
For that 2nd issue, did you perhaps intend to write programmers[i]
?

3,752 PointsI can't find the stray semicolon, but programmer was a typo. I meant to type programmers to use the names from the list of programmers since I think it was declared. I edited my code but now it will only print the first name and stop there. Teamtreehouse says I forgot to add a newline but Im not sure what that means. I removed %d and i+1 so I can focus on getting the list to show first, then I will number it later.
