Hello, I want help please.
How can I put live data in LinkedList for create a list few elements?

I try this code that put the new data in [0] index but no keep old data in the list as I would like.
List l = new LinkedList();
l.add(open);
for (int i = 0; i< l.size(); i++)
System.out.println(" Element à l'index " + i + "=" + l.get(i));
The code put the new data but remove the oldest.
My target is create a dynamic list of two elements, a new data and the previous.

Have a nice day!
Best regards

list.add(Object o); // Appends the specified element to the end of this list 
list.remove(int index) // Removes the element at the specified position in this list (optional operation).

Hence in this case we need the following

list.add(open);
list.remove(0);

Thank you for your help, I try this immediately.
Have a good weekend!!
