In Java, you are only allowed to define one public class per file. The name of the file has
to correspond to the name of the public class. In your example, the public class is
SprinklerSystem. Hence, the file containing the program has to be called
SprinklerSystem.java. The filename exer1.java would be valid if the name of the public class
was exer1.
