When you execute the CompareLoopTimes program shown in Figure 6-29, you will occasionally see a negative number output when the nanoseconds values retrieved fall in different seconds. Modify the program to fix this problem, and save the file as CompareLoopTimes3.java. (Hint: It might take hundreds or thousands of executions for you to catch the program near the end of a second in order to test your modifications. For testing purposes, you can assign values to the start and stop times instead of retrieving them from the LocalDateTime class.) Java program Using Eclipse
