Add method headers to the MessageSender interface.$($o$)$ Add a method header for a void return method called sendMessage that takes two arguments of type String, one for recipient, and one for message.$($p$)$ Add a method header for a void return method called receiveMessage that takes two String arguments, one for sender and one for message$\mathrm{.}7.$ Create a Java class file for an abstract class called AbstractCommunicationDevice that implements the MessageSender interface.a$)$ Add an instance variable deviceName to represent the name of the communication device.b$)$ Provide a constructor to initialize the deviceName variable in the abstract class called AbstractCommunicationDevice.c$)$ Implement methods declared in the MessageSender interface. A possible implementation would be to print out information to the console$\mathrm{.}8.$ Create another abstract Java class called Smartphone that extends AbstractCommunicationDevice.a$)$ Declare an instance variable batteryLevel to represent the battery level of the smartphone.b$)$ Implement a method checkBatteryLevel$()$ to display the current battery level.c$)$ Implement a parameterized constructor that initializes the device name and battery level of the Smartphone$\mathrm{.}9.$ Create a Java class file for the concrete class AndroidPhone that extends Smartphone. It should also implement the interface Mammoth.$($q$)$ Implement a parameterized constructor that initializes the device name and battery level of the Android phone. If an appropriate constructor from a superclass is available, override and utilize this constructor.$($r$)$ Override the sendMessage$($String recipient, String message$)$ method to display a message specific to sending messages from an Android phone.$($s$)$ Override the receiveMessage$($String sender$,$ String message$)$ method to display a message specific to receiving messages on an Android phone$\mathrm{.}10.$ Add code in the main$()$ method of main class file to test your implementation.a$)$ Create an instance of the AndroidPhone class.b$)$ Send and receive messages using the Android phone.c$)$ Display the battery level of the smartphone.d$)$ Your output might look like this:Samsung Galaxy is sending a message to Alice: Lunch today at $12.$Samsung Galaxy received a message from Bob: What time is the meeting today?Samsung Galaxy is sending a message to Bob: Meeting at $2$:$30$Battery level: $80\%11.$ Ensure that your code follows good coding practices, including appropriate naming conventions, comments, and indentation.
