Problem 2
Consider a program for managing inventory in a small appliance store. Why isn't it useful to have a superclass Sma11Appliance and subclasses Toaster, Carvacuur, Traveliron, and so on?
Problem 7
In an object-oriented traffic simulation system, we have the classes listed below. Draw an inheritance diagram that shows the relationships between these classes. \- Vehicle \- Sportutilityvehicle \- Car \- Minivan \- Truck \- Bícycle \- Sedan \- Motorcycle \- Coupe \- Pickuprruck
Problem 8
Implement a superclass person. Make two classes, Student and instructor, that inherit from person. A person has a name and a year of birth. A student has a major, and an instructor has a salary. Write the class declarations, the constructors, and the __repr. method for all classes. Supply a test program that tests these classes and methods.
Problem 8
What inheritance relationships would you establish among the following classes? \- Student \- Professor \- TeachingAssistant \- Exployee \- Secretary \- DepartnentChair \- Janitor
Problem 14
The Ceonetricshape class defines the fill and _out line instance variables for specifying the color used to draw a shape. But no methods were defined for accessing these values. Define the accessor methods getfill and getout 1 ine in the Ceonetricshape hierarchy as appropriate. Hint: if a shape class does not use one or both of the colors, no fill or outline value should be returned for instances of that class.
Problem 27
Resonant circuits are used to select a signal (e.gr, a radio station or 'TV channel) from among other competing signals. Resonant circuits are characterized by the frequency response shown in the figure below. The resonant frequency response is completely described by three parameters: the resonant frequency, \(\omega_{\mathrm{o}}\) the bandwidth, \(B\), and the gain at the resonant frequency, \(k\). Two simple resonant circuits are shown in the figure below, The circuit in (a) is called a parallel resonant circuit. The circuit in (b) is called a series resonant circuit. Both resonant circuits consist of a resistor having resistance \(R\), a capacitor having capacitance \(C\), and an inductor having inductance \(L\). These circuits are designed by determining values of \(R, C\), and \(L\) that cause the resonant frequency response to be described by specified values of \(m_{o}, B\), and \(k\). The design equations for the parallel resonant circuit are: $$ R=k, \quad C=\frac{1}{B R}, \text { and } \quad L=\frac{1}{\omega_{0}^{2} C} $$ Similarly, the design equations for the series resonant circuit are: $$ R=\frac{1}{k}, L=\frac{R}{B}, \text { and } C=\frac{1}{\omega_{\mathrm{o}}^{2} L} $$ Write a Python program that represents ResonantCircuit as a superclass and represents the SeriesResonantCircuit and FarallelResonantCircuit as subclasses. Give the superclass thrce instance variables representing the parameters \(\omega_{\mathrm{o}}, B\), and \(k\) of the resonant frequency response. The superclass should provide public methods to get and set cach of these variables. The superclass should also provide a display method that prints a description of the resonant frequency response. Each subclass should provide a method that designs the corresponding resonant circuit. The subclasses should also override the display method of the superclass to print descriptions of both the frequency response (the values of \(\omega_{\mathrm{o}} B\), and \(k\) ) and the circuit (the values of \(R, C\), and \(L\) ). All classes should provide appropriate constructors. Supply a program that demonstrates that the subclasses all work properly.
