Newbie - For each loop and functions

I'm just wondering how to put the value of the method, "test", into the for each loop. This is the nonfunctional code:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World");
        String test() {
            String var = "Iloveyou";
            return var;
        }
        for (char letters:test().toCharArray()) {
            System.out.println(letters);
        }
    }
}

Try taking the "test" method out of the "main" method (but still in class HelloWorld), add "public" before "String" for the "test" method, create an object in your "main" method (ex. HelloWorld obj = new HelloWorld();), then use dot notation to call "test()" on the object you created for the "in" part of your for loop (char letters: obj.test().toCharArray()).

To my understanding, you create objects of the class so you can use the methods in that class.
