A train protection system automatically applies the brakes of a train if the speed limit for a segment of track is exceeded, or if the train enters a track segment that is currently signaled with a red light (i.e. the segment should not be entered). Giving reasons for your answer, chose a reliability metric that might be used to specify the required reliability for such a system.
What will be an ideal response?
The most appropriate reliability metric is Probability of Failure on demand
(POFOD). This is the probability that the system will respond correctly when a
request is made for service at a given point in time. This metric is used for
protection systems where demands for service are intermittent and relatively
infrequent over the lifetime of the system.

Analyze the following code.
public class Test { public static void main(String[] args) { System.out.println(m(2)); } public static int m(int num) { return num; } public static void m(int num) { System.out.println(num); } } a. The program has a compile error because the two methods m have the same signature. b. The program has a compile error because the second m method is defined, but not invoked in the main method. c. The program runs and prints 2 once. d. The program runs and prints 2 twice.
