Question

I’m trying to learn java better and I got one question.

Say I got two collections, an ArrayList and a LinkedHashSet. Is it possible to make a function like this:

void print(collection c) {
    for (object tmp:c) {
        System.out.println(tmp);
    }
}

Answer 1

Watch your capitalization:

private void printCollection(Collection collection) {

   for (Object obj : collection) {
      System.out.println(obj);
   }
}
