Hence, the correct answer is option “B”.
Expert Solution & Answer
Explanation of Solution
Constant:
The variable is defined as constant variable when the data item cannot be changed while the program is running.
- Constants are mostly used to define default values.
- For example: PI has the constant value 3.14.
- Consider the following statement in a Java class, the number 143 is constant, every time the java application containing the below statement with constant 143 is executed, the value 143 is displayed.
System.out.println(143);

It is disadvantageous to use public variables in classes because ___________
It results in compilation error
It cannot control its values
It cannot be accessed by other variables
Its values cannot be initialized

Creating a class object is often called _____________ the class.
A. Car Class
Create a Python Program where you write a class
named Car that has the following data attributes:
• _ _year_model (for the car's year model)
• __make (for the make of the car)
• _ _speed (for the car's current speed)
The Car class should have an _init_ method that
accepts the car's year model and make as arguments.
These values should be assigned to the object's
_year_model and
make data attributes. It should
also assign 0 to the __speed data attribute.
The class should also have the following methods:
accelerate()
The accelerate method should add 5 to the speed data
attribute each time it is called.
brake()
The brake method should subtract 5 from the speed
data attribute each time it is called.
• get_speed()
The get_speed method should return the current speed.
Next, design a program that creates a Car object then
calls the accelerate method five times. After each call
to the accelerate method, get the current speed of the
car and display it. Then call the brake method…

- In previous chapters, you have created programs for the Greenville Idol competition. Now create a Contestant class with the following characteristics: The Contestant class contains public static arrays that hold talent codes and descriptions. Recall that the talent categories are Singing Dancing, Musical instrument, and Other. The class contains an auto-implemented property that holds a contestants name. The class contains fields for a talent code and description. The set accessor for the code assigns a code only if it is valid. Otherwise, it assigns I for Invalid. The talent description is a read-only property that is assigned a value when the code is set. Modify the GreenvilleRevenue program so that it uses the Contestant class and performs the following tasks: The program prompts the user for the number of contestants in this years competition; the number must be between 0 and 30. The program continues to prompt the user until a valid value is entered. The expected revenue is calculated and displayed. The revenue is $25 per contestant. The program prompts the user for names and talent codes for each contestant entered. Along with the prompt for a talent code, display a list of the valid categories. After data entry is complete, the program displays the valid talent categories and then continuously prompts the user for talent codes and displays the names of all contestants in the category. Appropriate messages are displayed if the entered code is not a character or a valid code.arrow_forwardclass Student(object): """Represents a student.""" def __init__(self, name, number): """All scores are initially 0.""" self._name = name self._scores = [] for count in range(number): self._scores.append(0) def getName(self): """Returns the student's name.""" return self._name def setScore(self, i, score): """Resets the ith score, counting from 1.""" self._scores[i - 1] = score def getScore(self, i): """Returns the ith score, counting from 1.""" return self._scores[i - 1] def getAverage(self): """Returns the average score.""" return sum(self._scores) / len(self._scores) def getHighScore(self): """Returns the highest score.""" return max(self._scores) def __str__(self): """Returns the string representation of the student.""" return "Name: " + self._name + "\nScores: " + \ " ".join(map(str, self._scores))arrow_forwardUse java languagearrow_forward

Create a class Computer which will have attributes: CPUName=string, CPUClockSpeed_ghz-float, memory_gb3float. Now derive two classes from the Computer class, PC which will have attributes: operatingSystem3string, model=int, hasGPU=boolean and second class will be Smartphone which will have attributes: OSversion=string, battery_mAH=int. Write following functions for each class: > Constructor/Destructor > Deep Copy Constructor Parameterised Constructor Getter/Setter for dimension and length/radius Function to write the information to data file in append mode. Write a main function to create a dynamic array of PC and smartphone. Also write a function to get the PC with max CPUClockSpeed_ghz. Note: Write those functions which are asked.

An Invoice should include four pieces of information as instance variables a part number (type String), a part description (type String),a quantity of the item being purchased (type int) and a price per item (double). Your class should have a constructor that initializes the four instance variables. Provide a set and a get method for each instance variable. In addition, provide a method named getInvoice Amount that calculates the invoice amount (i.e., multiplies the quantity by the price per item), then returns the amount as a double value. If the quantity is not positive, it should be set to 0. If the price per item is not positive, it should be set to 0.0.
