Model a physical entity as a Java Class (70 points) focus on Encapsulation This is an Object Modeling/Programming exercise - albeit around 1 (maybe 2) Object(s). Using the Radio Class implementation provided as a point of reference, thinkof a common (or maybe, not so common) physical device or appliance that's worthy of modeling as an Object Consider the following a. The basic operations/functionality of your device/appliance become public methods of the implementing Class (e.g., on, off, go, start, stop, ...) The internal structure (or how you envision the internal structure) of your device/appliance become the data members of the implementing Class This would include the internal piece-parts of the device and well as "state components". For example, modeling a bread toaster might require a "heat coil" as well as a "power on/off" indicator b. c. In the spirit of modularity, reusability, etc., private/protected methods can and should be used to implement sub-tasks performed by public methods In addition to Class members supporting (a) (b) (c) above, you also need to implement Either a public void main (String [t "launch" Class whose only job will be to method or a second Create an instance of your modeled Class o Invoke a sequence of methods on that instance that demonstrates the functionality and basic usefulness of what you built. o A "string tostrin)"method - allowing you to display the state' of the Object Instancee What do we mean by the state of the Instance? The collective value of all data members 'at a moment in time' is considered the in stance's state That's a valid definition of state. but for this lab, customize the Class tostring() method to display values of data members that are considered significant to the device/application's operation Note: Refer to the Radio Class' tostring() andmain () methods as a guide. Also refer to the Radio's execution outputbelow - showing thata single instance has been created, and taken through a series of operations (method invocations). At critical points, a "toString" representation of the instance's state is displayed to the console using system.out.println )orthe like
