    Default Re: What's wrong with this code

    The variable city is assigned the values from the list vo one by one as the for loop executes.
    for(String city:vo) {
       System.out.println(vo);   // should print city NOT vo
    }

    See the tutorial: https://docs.oracle.com/javase/tutor...bolts/for.html
    Look at the discussion of enhanced for near the bottom.

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
