Computer Science Question:

I need to create a new linked-list class that implements the class shown in the photo. This new class needs to do all these methods recursively. So can someone help get me started and do the "size()" and "insertFirst()" methods. Thanks.

11 public interface L Interface T, extends rterableets f 130 le. 14 g Returns the number of elements in this (etink Listrnterface).
