Suppose a class Car and its subclass Honda both have a method called speed as part of the class definition. rentalH refers to an object of the type Honda and the following statements are found in the code: rentalh.cost(); super.speed(); what will the first statement do?
A. Nothing will be called since the code will not compile as a result of multiple definitions of speed.
B. The cost method in Car will be called.
C. The cost method in Honda will be called.
D. Overloading will be used to determine which cost method to use.

Answers

Answer 1

Answer:

C. The cost method in Honda will be called.

Explanation:

The first statement will cause the cost method in Honda to be called. This is because rentalh is a object of the subclass Honda. Therefore, any method that is called using this object variable will target the elements within the Honda subclass. In this case, the cost() method is being called using the rentalh variable which will look for the cost() method within the scope of the Honda subclass. In order to target the parent class Car it would need to be called using the super variable as in statement 2.

Define a method pyramidVolume with double parameters baseLength, baseWidth, and pyramidHeight, that returns as a double the volume of a pyramid with a rectangular base. Relevant geometry equations: Volume

Answers

Question:

Define a method pyramidVolume with double parameters baseLength, baseWidth, and pyramidHeight, that returns as a double the volume of a pyramid with a rectangular base. Relevant geometry equations:

Volume = base area x height x 1/3

Base area = base length x base width.

(Watch out for integer division)

import java.util.Scanner;

public class CalcPyramidVolume {

   /* Your solution goes here */

   public static void main (String [] args) {

     System.out.println("Volume for 1.0, 1.0, 1.0 is: " + pyramidVolume(1.0, 1.0,   1.0));

     return;

    }

}

Answer:

import java.util.Scanner;

public class CalcPyramidVolume {

   /* Your solution goes here */

   public static void main (String [] args) {

       System.out.println("Volume for 1.0, 1.0, 1.0 is: " + pyramidVolume(1.0, 1.0, 1.0));

       return;

   }

   

   //Begin method definition

   public static double pyramidVolume(double baseLength, double baseWidth, double pyramidHeight){

       

       //First, calculate the base area of the pyramid

       //store the result in a double variable

       double baseArea = baseLength * baseWidth;

       

       //Then, calculate the volume of the pyramid

       //using the base area and the base width

       double volume = 1 / 3.0 * baseArea * pyramidHeight;

       

       //return the volume

      return volume;

   }

}

Output:

Volume for 1.0, 1.0, 1.0 is: 0.3333333333333333

Explanation:

The code above contains comments explaining the important lines of the code. The output of the code has also been provided above.

The parts of the code that are worth noting are:

(i) The return type of the method pyramidVolume should be a double since calculations are done using double values. i.e the method header should be written as

public static double pyramidVolume(){

}

(ii) The method requires three(3) parameters of type double: baseLength, baseWidth and pyramidHeight. These should be included in the method. Therefore, the complete header definition should be:

public static double pyramidVolume(double baseLength, double baseWidth, double pyramidHeight){

}

(iii) The formula for calculating the volume of the pyramid should be:

volume = 1 / 3.0 * baseArea * baseWidth;

Rather than;

volume = 1 / 3 * baseArea * baseWidth;

This is because integer division yields integer result. If 1 / 3 is evaluated, the result will be 0 since the decimal part will be truncated thereby making the result of the volume = 1 / 3 * baseArea * baseWidth will be 0.

Therefore, the work around for that should be to write 1 / 3.0 or 1.0 / 3.0 or 1.0 / 3.

(iv) After the calculation, the result of volume should be returned by the method. This will enable a proper call by the main method for execution.

What is not an advantage of a computer network?


Select one:

A.Remote Information Access

B.Interaction among cooperative application programs

C.Social Engineering

D.User Communication

E.Resource Sharing​

Answers

Answer:

C. Social Engineering

Explanation:

Social engineering can be defined as an art of manipulating people, especially the vulnerable to divulge confidential information or performing actions that compromises their security.

Basically, it is a manipulative strategy or technique that involves the use of deceptive and malicious activities on unsuspecting victims in order to gain unauthorized access to their confidential or private information for fraud-related purposes. Some examples of social engineering attacks include quid pro quo, spear phishing, baiting, tailgating, water-holing, vishing, pretexting, phishing, etc.

Phishing is an attempt to obtain sensitive information such as usernames, passwords and credit card details or bank account details by disguising oneself as a trustworthy entity in an electronic communication usually over the internet.

Furthermore, phishing is a type of fraudulent or social engineering attack used to lure unsuspecting individuals to click on a link that looks like that of a genuine website and then taken to a fraudulent web site which asks for personal information.

In conclusion, social engineering being a form of cyber attack is not an advantage of a computer network.

I need solutions to below questions with python code:
Write a program, my_family.py For Loop A program, work-list.pyList
1. that contains a Tuple holding the names of friends or family members. Then use a For Loop to read and print the names.
2. that contains a of six integers. Use a list method to add one more integer. Use a list method to sort the list. Use a While Loop to print the entries.

Answers

Answer:

1) my_family.py

family = ('Dad', 'Mom', 'Agnes', 'David', 'Chris', 'Millie')

for name in range(len(family)):

   print(family[name])

2) work_list.py

my_number = [2, 6, 3, 1, 8, 4]

# add items at the end of the list.

my_number.append(0)

my_number.append(5)

# sorts the list, default - ascending.

my_number.sort()

size = 0

while size < len(my_number):

   print(my_number[size])

   size += 1

Explanation:

The tuple and list data structures are ordered, using indexes to locate items in its container.

The family.py file uses the for-loop to iterate and print the family names in the tuple.

The work-list.py file contains a list of integers which is modified by adding items at the end of the list with the append method and a prints all the items using a while-loop.

A program developed for a Web store represents customer account balances using a format that approximates real numbers. While testing the program, a software developer discovers that some values appear to be mathematically imprecise. Which of the following is the most likely cause of the imprecision?
A. The account balances are represented using a fixed number of bits, resulting in overflow errors.
B. The account balances are represented using a fixed number of bits, resulting in round-off errors.
C. The account balances are represented using an unlimited number of bits, resulting in overflow errors.
D. The account balances are represented using an unlimited number of bits, resulting in round-off errors.

Answers

Answer:

B.

Explanation:

The most likely reason for this would be that the account balances are represented using a fixed number of bits, resulting in round-off errors. Since all of the numbers being used are real numbers they would have a fixed 32 bits of data. When these values are multiplied or divided they can be irrational numbers that never end, and therefore are cut off in order to fit the available data. This would cause the numbers to be rounded and can lead to the answer being imprecise.

S -> M

M -> YYY

Y -> c | g

L -> XX

X -> b | c | g

R -> ZZZ

Z -> a | b

Explanation:

This is a long time ago, but I think this does what you want.

Start symbol S expands to LSR and allows you to grow L and R on either side as much as you want. Ultimately S must be replaced by M. Then you have a pattern like LLLLLMRRRRR.

We can then further break down L into 2 times b, c or g, and similar for M and R.

Answer:

The program in Java is as follows:

import java.util.Scanner;

public class Main{

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

 double n1, n2;

 n1 = input.nextDouble();

 n2 = input.nextDouble();

 double Max = Math.max(n1,n2);

 double Min = Math.min(n1,n2);

 System.out.println("Max: "+Max);

 System.out.println("Min: "+Min); }}

Explanation:

This declares the numbers

 double n1, n2;

This gets input for n1

 n1 = input.nextDouble();

This gets input for n2

 n2 = input.nextDouble();

This gets the max of both using the max function

 double Max = Math.max(n1,n2);

This gets the min of both using the min function

 double Min = Math.min(n1,n2);

This prints the max

 System.out.println("Max: "+Max);

This prints the min

 System.out.println("Min: "+Min);
