Implement a Linked List as a subclass of the abstract List class.
Make sure it works in all these cases:
1. insert(element, 0) should work if head is null
2. insert(element, 0) should update head
3. remove(0) should update head
4. Copying an empty list should work
Solution
import java.util.LinkedList;
import java.util.List;
public class listest {
public static void main(String[] args) {
List l=new LinkedList();
l.add(0, 51);
System.out.println(\"Element at 0: \"+l.get(0));
l.add(0, 23);
System.out.println(\"Element at 0: \"+l.get(0));
l.remove(0);
System.out.println(\"Element at 0: \"+l.get(0));
List l1=new LinkedList();
l1=l;
System.out.println(\"Element at 0 in new list:\"+ l1.get(0));
}
}
