There is a class hierarchy that includes three classes: class Animal {    protected int age;    public int getAge() {        return age;    }    public void setAge(int age) {        this.age = age;    }}class Pet extends Animal {    protected String name;    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }}class Cat extends Pet {        protected String color;    public String getColor() {        return color;    }    public void setColor(String color) {        this.color = color;    }} Given the following object: Pet cat = new Cat(); Select all invalid method invocations.

StockReader Class • This class will contain the method necessary to read and parse the .csv file of stock information. • This class shall contain a default constructor with no parameters. The constructor should be made private. . This is to prevent the class from being instantiated since the class will only contain static methods. • This class shall contain no data fields. • This class shall have a method called readStockData: . This method shall be a public, static, method. . This method shall return a StockList object once all data has been processed. . This method will take a File object as a parameter. This File object should link to the stock market data in your files folder created previously. . This method must validate that the given File object is a .csv file. If it is not, then this method shall throw an IllegalArgumentException. . This method shall read the File object and process all of the stock data into TeslaStock objects and store each object in a StockList. NOTE: The…

A class object can encapsulate more than one [answer].

When you instantiate an object from a class, you give a name to this particular object so that your program can distinguish it from other objects you instantiate from the same class.  True  False

Lab 2 – Designing a class   This lab requires you to think about the steps that take place in a program by writing pseudocode. Read the following program prior to completing the lab.   Design a class named Computer that holds the make, model, and amount of memory of a computer. Include methods to set the values for each data field, and include a method that displays all the values for each field.   For the programming problem, create the pseudocode that defines the class and enter it below. Enter pseudocode here

Summary In this lab, you create a derived class from a base class, and then use the derived class in a Python program. The program should create two Motorcycle objects, and then set the Motorcycle’s speed, accelerate the Motorcycle object, and check its sidecar status. Instructions Open the file named Motorcycle.py. Create the Motorcycle class by deriving it from the Vehicle class. Call the parent class __init()__ method inside the Motorcycle class's __init()__ method. In theMotorcycle class, create an attribute named sidecar. Write a public set method to set the value for sidecar. Write a public get method to retrieve the value of sidecar. Write a public accelerate method. This method overrides the accelerate method inherited from the Vehicle class. Change the message in the accelerate method so the following is displayed when the Motorcycle tries to accelerate beyond its maximum speed: "This motorcycle cannot go that fast". Open the file named MyMotorcycleClassProgram.py. In the…

When a class uses dynamically allocated objects for its members and it does not have a copy assignment operator what of the following could happen (mark all that apply) There could be runtime errors There could be a double frees (double delete errors) There could be memory leaks Nothing happens the compiler provides the correct constructor There could be compile time errors
