Scientists in a certain laboratory are working with a linked list class that uses recursion to compute its size. The scientists know that an empty list has size 0, so they never ask a linked list to compute its size when the list is empty. Under these circumstances,

A) the recursive method can become more efficient by eliminating the test for a base case B) the recursive method should still handle the base case of an empty list, because it will still occur even though the scientists never ask for the size of an empty list C) the recursive method can be modified to use a list of size 1 as the base case D) B and C are both correct

Compile HTTPClient.java, as shown in Figure 7. Run it to contact a web server whose name you know (you don’t need to have access to it) to (i) fetch a file you know that exists, and (ii) fetch a file that you know that does not exist. Capture the output of each run on hardcopy. Analyze the lines in the response from the server in each case and identify the different parts (status line, header line(s), and body) in each case.
