Answer:

The solution code is written in Python:

class Carpet:
def __init__(self, rect, cost):
self.size = rect
self.costPerSqFoot = cost
def cost(self):
carpetCost = self.size.area() * self.costPerSqFoot
return carpetCost

Explanation:

Presume that there is existence of Rectangle class as given in the question, Carpet class is written. The Carpet constructor is defined that take Rectangle object, rect, and cost as parameter (Line 2). To create data member of Carpet class, keyword "self" is used to precede with the name of the data members, size and costPerSqFoot (Line 3-4). The data members are initialized with the parameter rect and cost, respectively.

Next, cost method is defined (Line6 - 8). Within the cost method, the area method of Rectangle object is invoked by expression, self.size.area() and this will return the area value and multiplied with the costPerSqFoot to get the carpet cost and return it as output (Line 8).

Constructors have the same name as the ____.1. data members2. member methods3. class4. package

Svetradugi [14.3K]

Answer:

(3) option is the correct answer.

Explanation:

Constructors need to initialize the object in the memory. "To declare the Constructor for any class the user needs to specify the constructor name which is already the class name". This is an object-oriented language guideline.

It is because the object is created by the name of the class and Constructor is used to allocate the memory for the object. hence Constructor is created by the name of the class.

For example--

class test //class name test

{

test() //created a constructor with class name "test"

{

}

In the above example class name and constructor name are same if it not then it will gives a error.

Another option is not valid for the answer to the above problem because-

Option 1 is wrong because, for any class, the data member is a type of variable, which is used to store the data and is accessed with the help of an object.
Option 2 is wrong because, for any class, member function is a type of user function used to accessed the variable and expressions.
Option 4 is wrong because, package is a set used to hold classes and interfaces.

The true or false questions.

tankabanditka [31]

Answer:

false

Explanation:

-exec option is not mandatory for the find command.

find will still list out the identified files even in the absence of -exec option.

For example:

find . -name test -print

will print out files with the name 'test' in the current directory. Note that there is no exec option in this example.

Same holds true for find with no additional options at all.

For example:

find .

will list out all files in the current directory.

Write a method maxMagnitude() with two integer input parameters that returns the largest magnitude value. Use the method in a pr

yawa3891 [41]

Answer:

The program in Java is as follows:

import java.util.*;

import java.lang.Math;

public class Main{

public static int maxMagnitude(int num1, int num2){

int mag = num2;

if(Math.abs(num1) > Math.abs(num2)){

mag = num1;

}

return mag;

}

public static void main(String[] args) {

int num1, num2;

Scanner input = new Scanner(System.in);

System.out.print("Enter two integers: ");

num1 = input.nextInt();

num2 = input.nextInt();

System.out.println(maxMagnitude(num1,num2));

}

Explanation:

The method begins here

public static int maxMagnitude(int num1, int num2){

This initializes the highest magnitude to num2

int mag = num2;

If the magnitude of num1 is greater than that of num2

if(Math.abs(num1) > Math.abs(num2)){

mag is set to num1

mag = num1;

}

This returns mag

return mag;

}

The main method begins here

public static void main(String[] args) {

This declares num1 and num2 as integer

int num1, num2;

Scanner input = new Scanner(System.in);

This prompts the user for two integers

System.out.print("Enter two integers: ");

This gets input for the first integer

num1 = input.nextInt();

This gets input for the second integer

num2 = input.nextInt();

This calls the maxMagnitude method and prints the number with the highest magnitude

System.out.println(maxMagnitude(num1,num2));

}

What types of storage can be used to access your data on another computer?

Ivenika [448]

You could use cloud storage. Basically, the things you save are actually saved on another computer, that is, on another server, that is used as a hard drive for many pcs. You can access the cloud storage if you have internet and it works like a normal hard drive. There are even laptops that don't have storage other than cloud storage.
