Write a class that can make comparisons between the efficiency of the common methods from the List interface in the ArrayList and LinkedList classes such as add, get, and remove. Use the polymorphic-variable technique described above to write the class so that it only knows it is performing its tests on objects of the interface type List rather than on the concrete types ArrayList and LinkedList. Use large lists of objects for the tests, to make the results significant. You can use the currentTimeMillis method of theSystem class for getting hold of the start and finish time of your test methods.

The following function returns a string of length n whose characters are all 'x'. give the order of growth (as a function of n) of the running time. recall that concatenating two strings in java takes time proportional to the sum of their lengths. public static string f(int n) { if (n == 0) return ""; if (n == 1) return "x"; return f(n/2) + f(n - n/2); } options: a) constant b) logarithmic c) linear d) linearithmic e)quadratic f)cubic g) exponential
