Assume that a gallon of paint covers about 350 square feet of wall space. Create anapplication with a main() method that prompts

Elena-2011 [213]

Answer:

import java.util.Scanner;

public class PaintClculator {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.println("Enter Values for length, width, and height of the room");

double length = in.nextDouble();

double width = in.nextDouble();

double height = in.nextDouble();

double wallArea = calculateWallArea(length,width,height);

double noGallons = calculatePaint(wallArea);

double price = price(noGallons);

System.out.println("Price is: "+ price);

}

// Creating Method to Calculate Wall Area

public static double calculateWallArea( double length, double width, double height){

// formular for the surface area of a room Area=2*length*heigth+2*width*height+lenth*width

double Area = 2*length*height+2*width*height+length*width;

System.out.println("Wall Area: "+Area);

return Area;

}

//Creating method to calculate amount of paint

public static double calculatePaint(double Area){

double noGallons = Area/350;

System.out.println("Number of gallons: "+noGallons);

return noGallons;

}

// Creating Method Calculate Price

public static double price(double noGallons){

return noGallons*32;

}

Explanation

Created Three Methods in all; calculateWallArea(), calculatePaint(), and price()
Method calculateWallArea() calculates area based on this formula Area=2*length*heigth+2*width*height+lenth*width
The value of Area is passed to method calculatePaint() Which calculates the number of gallons required to cover the area given that one gallon covers 350 wall space
Method price() calculates and dis[plays the price by calling method calculatePaint() that returns number of gallons. since one gallon is 32$

Given the following method definitions: void mystery(double a) { System.out.print("double! "); } void mystery(int a) { System.ou

kicyunya [14]

Answer:

The correct answer to the following question is option "b".

Explanation:

The method having the same name but the arguments have different so it is called method overloading. It is a part of the object-oriented programming language (oops).

In the given code we define same method two times that is "mystery()". but in this method, we pass two different parameters. For the first time, we pass a double variable that is "a" as a parameter. In the second time, we pass an integer variable that is "a" as a parameter and in both functions, we write some codes.
In the calling time, we call function two times. In first time calling we pass an integer value that is "1" and second time calling we pass double value that is "1.0". So the output of this code is "int! double!".

That's why the option "b" is correct.

Vivian wants to increase the storage capacity of her computer. Which components should she upgrade?

Nikitich [7]

Answer:

Hard drive

Explanation:

The hard drive is where the operating system, programs and data reside on (unless the data is saved and backed up elsewhere). An older hard drive that uses platters for reading and writing data to it will be slower than a later model solid state device. Newer hard drives have very fast access speeds compared to older units.

Write a program that asks the user how many numbers will be entered and then has the user enter those numbers. When this is done

KATRIN_1 [288]

Answer:

The program written in Python 3 is as follows;

The program does not make use of comments; however, see explanation section for detailed line by line explanation of the program

num = int(input("Number of Inputs: "))

mylist = []

userinput = int(input("Enter a digit: "))

i = 1

while i < num:

mylist.append(userinput)

userinput = int(input("Enter a digit: "))

i += 1

try:

first7 = mylist.index(7)+1

print('The first position of 7 is ',first7)

last7 = num - 1 - mylist[::-1].index(7)

print('The last position of 7 is ',last7)

except:

print('7 is not on the list')

Explanation:

This line prompts user for the number of inputs

num = int(input("Number of Inputs: "))

This line declares an empty list

mylist = []

This line inputs the first number into the empty list

userinput = int(input("Enter a digit: "))

The italicized lines represent an iteration that allows user to input the numbers into the empty list.

i = 1

while i < num:

mylist.append(userinput)

userinput = int(input("Enter a digit: "))

i += 1

The try-except is used to check the presence of 7 in the list

try:

This checks the first occurrence of 7

first7 = mylist.index(7)+1

This prints the first occurrence of 7

print('The first position of 7 is ',first7)

This checks the last occurrence of 7

last7 = num - 1 - mylist[::-1].index(7)

This prints the last occurrence of 7

print('The last position of 7 is ',last7)

The following is executed if there's no occurrence of 7

except:

print('7 is not on the list')
