Must be coded in java Examples are Programming exercise exemplifying a tv/microwave This is an Object Modeling/Programming exercise albeit around 1 (maybe 2) Object. Using the Radio Object we reviewed in class as a point of reference, think of a common (or maybe, not so common) physical device or appliance thats worthy of modeling as an Object. Consider the following: 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. In the spirit of modularity, reusability, etc., private/protected methods can and should be used to implement public method sub-tasks. In addition to Class members supporting (a) through (c) above, you also need to implement: Either a public void main(String [] ) method or a second test harness Class whose only job will be to: Create an instance of your modeled Class Invoke a sequence of methods on that instance designed to show that its being taken A String toString() method allowing you to display the state of the Object Instance. What do we mean by the state of the Instance? Normally, the collective value of all data members at a moment in time is considered the instances state. Thats a very 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/applications operation. Note: Refer to the Radio Class toString() and main() methods as a guide. See Rodios execution output below showing that a single instance has been created, and taken through a series of operations (method invocations). At key points, a toString() representation of the instances state is displayed to the console using System.out.println()or the like.
