Printing out in main

I have this code to print all elements out in an array

public void printChildren(ArrayList<Person> child){

for (int i = 0 ; i < child.size(); i++)
System.out.println( child.get(i).getName() + " " + child.get(i).getAge());



}
}

But I cant really make it work in the main.... trying to call it but I only get error.. so how can I call it or print it from the main

thanks

What error are you getting?

if you add static keyword to your function declaration of printChildren, then you'll be able to call this function from main.

hope this helps. :)
