This Java program serves as a comprehensive test suite for classes representing different models of TVs and smartphones. It meticulously tests various functionalities such as channel changing, volume adjustment, voice interface commands, and multimedia capturing capabilities. Additionally, the program ensures type conformance with the TV and smartphone classes, as well as the VoiceAssistant and Logger interfaces. Through a series of test cases, the program demonstrates the robustness and compatibility of the implemented functionalities across different device models. Overall, this test driver provides a thorough evaluation of the implemented classes and interfaces, ensuring their correctness and interoperability.
This abstract class represents a generic TV and implements the Logger interface to enable logging functionality. It contains fields for the current channel, current volume, and model of the TV, as well as methods for adjusting the channel and volume, changing the channel, and logging messages. The class provides a visual string representation of the TV's current state, including its channel, volume, and model.
This class represents a TV from the Star brand and extends the TV class. It inherits the functionalities of the TV class, including channel and volume adjustment, channel changing, and logging. The constructor sets the model of the TV to "star" using the superclass constructor.
This class represents a TV from the Nebula brand and extends the TV class while implementing the VoiceAssistant interface. It provides voice control functionality, including methods for generating speech output and processing speech inputs to control the TV. The constructor sets the model of the TV to "nebula" using the superclass constructor.
This abstract class represents a generic smartphone and implements the VoiceAssistant and Logger interfaces to provide voice control and logging functionalities. It includes abstract methods for taking pictures and talking on the phone, as well as methods for processing speech commands, logging messages, and recharging the battery. The constructor initializes the smartphone with the given battery capacity and model.
This class represents a smartphone model P8, extending the Smartphone class. It includes methods for taking pictures and talking on the phone. The constructor initializes a new P8 smartphone with a battery capacity of 2000 and a model name "p8". The takePicture method captures a picture with a specific resolution and reduces the current battery amount accordingly. The talkOnPhone method simulates talking on the phone for a specified number of minutes and adjusts the battery amount based on the duration of the call.
This class represents a smartphone model P10, extending the Smartphone class. It includes methods for taking pictures, recording videos, talking on the phone, and processing speech commands specific to the P10 model. The constructor initializes a new P10 smartphone with a battery capacity of 2900 and a model name "p10". The takePicture method captures a picture with specific resolution and adjusts the current battery amount accordingly. The talkOnPhone method simulates talking on the phone for a specified number of minutes and adjusts the battery amount based on the call duration. The takeVideo method records a video for a specified number of seconds and reduces the battery amount accordingly. The processSpeech method processes speech commands for the P10 smartphone, including taking pictures, recording videos, and talking on the phone.
This interface represents a logger and includes a method for writing a message to a log file. Classes that implement this interface must provide an implementation for the writeToLogFile method.
This interface represents a voice assistant and includes methods for processing speech commands and generating speech output. Classes that implement this interface must provide implementations for the processSpeech and saySomething methods.
This class represents an exception thrown when a speech input is not understood by a voice assistant. It extends the Java Exception class and provides a constructor to create a new instance with a specified detail message.
The classes and interfaces provided create a cohesive system for modeling and interacting with TVs and smartphones, focusing on functionality such as channel changing, volume adjustment, voice control, and logging. The TV class serves as a base for generic TV functionality, while StarTV and NebulaTV extend it to represent specific TV models, with NebulaTV additionally implementing the VoiceAssistant interface for voice control functionality. The Smartphone abstract class provides a blueprint for generic smartphone features, with P8 and P10 representing specific models and implementing the VoiceAssistant interface. Both smartphones also implement the Logger interface to access logging functionality. The Logger interface and Logger class allow for logging messages from both TVs and smartphones, enhancing debugging and monitoring capabilities. The VoiceAssistant interface defines methods for processing speech commands and generating speech output, crucial for enabling voice control in TVs and smartphones. The SpeechNotUnderstoodException class provides a way to handle cases where a speech input cannot be understood, improving the user experience by allowing for error handling and feedback. Each class component plays a vital role in creating a flexible and extensible system for managing and interacting with TVs and smartphones efficiently.
