Attentiveness Evaluation

The attentiveness evaluation test in my driving school was easier than one I developed by using JavaFX. I made it harder by adding the next value randomly. javafx({ name: "Attentiveness", width: 300, height: 300, archive: "https://malenkov.dev.java.net/20100716/Attentiveness.jar" }); The test data are stored in the PersistentProperties class that combines the Storage and the Properties classes. When you create its instance, all the key-value pairs are loaded from the specified storage. This class provides utility methods to convert a string value into the expected type. For example, public function getInteger(key, default: Integer) { var value = get(key); if (value != null) try { return Integer.parseInt(value) } catch (exception) { } default } This method takes a string value for a given key and tries to parse it as an Integer value. If the value is not found or it could not be parsed, the method returns the default value. I think, it might be helpful to have such utility methods in the Properties class. The PersistentProperties class is used in this test as well as in the previous one. The application model based on this class is used to store the data when they are changed. Study the PersistentModel class in detail. public class PersistentModel { def properties = PersistentProperties { source: "properties.txt" } First, the data storage is initialized. public var misses =...
