I need help programming 3.2.12 and 3.2.13 if you will. This is in Java the first post is the question and the second is the program. If you can only answer one at a time that is fine too.

API: Point (double x, double y) double distanceTo(Point q) String tostringO 2 Add methods to Stopwatch that allow clients to stop and restart the stop- watch. 12.13 Use Stopwatch to compare the costof computing harmonic numbers with a for loop (see PROGRAM 1.3.5) as opposed to using the recursive method given in SECTION 2.3. 3214 Develop a version of Histogram that uses Draw, so that a client can create mutiple histograms. Add to the display a red vertical line showing the sample mean and blue vertical lines at a distance of two standard deviations from the mean. Use a tst dient that creates histograms for flipping coins (Bernoulli trials) with a biased coin that is heads with probability p, for p = 0.2, 0.4, 0.6. and 0.8, taking the number
