2: System Timing static long currentTimeMillis() Current time in milliseconds. currentTimeMillis() - start; Be careful to only time the algorithm in question. Given the speed of current computers, it is common to loop over several executions and then calculate the average time. An advantage of this approach is that it can be a reality check for an abstract analysis. If your analysis is correct, then real performance times should confirm it. However, beware of machine factors that may impact actual performance, especially caches.

Suppose s is a reference to a Java string. Write expressions to return each of these values: (a) The length of s (b) The third character in s (as in, the third character of “abcd” is “c”) (c) The substring of s consisting of its third through fifth characters (d) The substring of s consisting of its fourth character to the end 6.

Have the constructor make sure all denominators are positive, so that negative fractions have a negative numerator. abs() library function if you need absolute value.
