List Help
I'm extremely new to Java, so having some syntax issues. I'm trying to learn some data structures, and getting an error. Not sure why....
Code:
import java.util.List;
public class MyList {
public static void main(String[] args) {
List<String> l = new List<String>();
l.add("HELLO WORLD");
}
}
On the first line in main() I get this error: Cannot instantiate the type List<String> Anybody know what this means? Any help would be greatly appreciated...

List is an interface. You can't instantiate interfaces. In order to get an instance you must use an implementing class such as LinkedList or ArrayList.
