1.9 Sometimes it is useful to measure the length of time it takes for a piece of code to run. (For example, it may help determine where optimizations of your code would be most effective.) Design a Stopwatch class to support tim- ing of events. You should consider use of the nanosecond clock in the Java environment, System. nanoTime (). Like many stopwatches, it should support starting, temporary stopping, and a reset. The design of the protected section of the stopwatch should hide the implementation details.
