This is Java

Which of the following describes a valid way to compare the efficiency of two equivalent algorithms written in Java? Carefully count the number of lines of code in each of the algorithms to see which has more. Write lines of code which calculate statement execution counts and compare these values for a range of inputs. Rewrite both algorithms in a different language and test them to see if they still work. Check the outputs given by the two different algorithms for a range of inputs and compare the accuracy of these. None of the items listed. Question 19 Consider the following code segment? String str = "result"; String result =""; for (int i=0;i
