How to retrieve List contents?

Question

Yes! I've searched the forum already, but I see no clear answer or maybe it's just that I'm new to Java and can't quite understand everything...
Somewhere on the application a List is filled with data. Now say I want to print the contents of this List, (not the object reference), how do I do it? I know how to loop it with hasNext and stuff, but I don't know how to view its real data! Is there a simple way to do it?
I've tried using methods like Iterator, listIterator, toString, get etc... but no joy :(
I don't even know if that's how it's done! Please help! Thanks in advance

Answer 1

List myList = new ArrayList();
myList.add("Hello");
myList.add("World!");
for(Object o : myList) {
System.out.println(o.toString());
}A couple of side note on the above in case the OP sees it:
The toString() call on 'o' is redundant, as println(Object) will implicitly invoke the toString() method on the parameter.
To just print the contents of a List, it would be more simple to just do:
System.out.println(myList);
Again, the toString() method is implicitly invoked (on the ArrayList object in this case), which is implemented to iterate over itself, returning a String containing each element's toString().
