What is illustrated in the cells to the right of the Fourth Quarter column?

Does the submission include the file "SuperPower.java"? Does the file include a public class called "SuperPower"? Does the class

Oduvanchick [21]

Answer:

Here is the program fulfilling all the requirements given:

import javax.swing.JOptionPane;

public class SuperPower{

public static void main(String[] args) {

String power;

power = JOptionPane.showInputDialog("What is your super power?");

power = power.toUpperCase();

JOptionPane.showMessageDialog(null, power);} }

Explanation:

Does the file include a public class called "SuperPower"

See the statement:

public class SuperPower

Does the class include a public method called "main"? Is the "main" method static?

See the statement:

public static void main(String[] args)

Does the main method have a String assignment statement that uses "JOptionPane.showInputDialog"

See the statement:

power = JOptionPane.showInputDialog("What is your super power?");

Does the main method have a statement that uses "JOptionPane.showMessageDialog"?

See the statement:

JOptionPane.showMessageDialog(null, power);

Does the program convert the String from "JOptionPane.showInputDialog" using the "toUpperCase" method?

See the statement:

power = power.toUpperCase();

Does the submission include a screenshot that shows an Input dialog that asks, "What is your superpower?" Does the submission include a screenshot that shows a Message dialog stating " TO THE RESCUE!", where "" is the input converted to upper case?

See the attached screenshots

If the program does not let you enter an exclamation mark after "to the rescue" then you can alter the code as follows:

import javax.swing.JOptionPane;

public class SuperPower{

public static void main(String[] args) {

String power;

power = JOptionPane.showInputDialog("What is your super power?");

power = power.toUpperCase();

JOptionPane.showMessageDialog( null, power+"!");} } // here just add an exclamation mark which will add ! after the string stored in power

Answer:

your friend just sent you 32 bits of pixel data (just the 0s and 1s for black and white pixels) that were encoded after sampling an image. Choose the two statements that are true.

------------------

The 32 bits of pixel data is enough to produce the image using the widget. Nothing else is needed.

------------------------

The digital image would be an exact copy of the analog image.

-----------------------------The correct width and height must be input into the pixelation widget to produce the image.

---------------------------The fact that only 32 bits were used to represent the image indicates relatively large sample squares were used. The digital image may vary from the analog image significantly

A painting company has determined that for every 115 square feet or wall space, one gallon of paint and eight hours of labor wil

Kay [80]

The program to calculate the total paint cost and other values is given below.

#include <iostream>

using namespace std;

int main() {

int rooms, laborChrg = 18;

float paintChrg;

float feetPerRoom[rooms];

float paintReq, laborHrs, paintCost, laborCost, totalCost, totalsqft=0;

cout<<"Enter the number of rooms to be painted "<<endl;

cin>>rooms;

for(int i=0; i <= rooms; i++)

{

cout<<"Enter the square feet in room "<<endl;

cin>>feetPerRoom[i];

// shortcut operator which is equivalent to totalsqft = totalsqft + feetPerRoom[i];

totalsqft += feetPerRoom[i];

}

cout<<"Enter the cost of the paint per gallon "<<endl;

cin>>paintChrg;

laborHrs = (totalsqft/115)*8;

laborCost = laborHrs * laborChrg;

paintReq = totalsqft/115;

paintCost = paintReq * paintChrg;

totalCost = laborCost + paintCost;

cout<<"The number of gallons of paint required "<<paintReq<<endl;

cout<<"The hours of labor required "<<laborHrs<<endl;

cout<<"The cost of the paint is "<<paintCost<<endl;

cout<<"The labor charges are "<<laborHrs<<endl;

cout<<"The Total cost of the paint job is "<<totalCost<<endl;

return 0;

}

Explanation:

The header files for input and output are imported.

#include <iostream>

using namespace std;

All the variables are taken as float except labour charge per hour and number of rooms.

The user is asked to input the number of rooms to be painted. An array holds the square feet in each room to be painted.

cout<<"Enter the number of rooms to be painted "<<endl;

cin>>rooms;

for(int i=0; i <= rooms; i++)

{

cout<<"Enter the square feet in room "<<endl;

cin>>feetPerRoom[i];

totalsqft += feetPerRoom[i];

}

The above code asks for square feet in each room and calculates the total square feet to be painted simultaneously.

All the data to be displayed is calculated based on the values of labor charge per hour and gallons of paint needed, given in the question.

laborHrs = (totalsqft/115)*8;

laborCost = laborHrs * laborChrg;

paintReq = totalsqft/115;

paintCost = paintReq * paintChrg;

totalCost = laborCost + paintCost;

All the calculated values are displayed in the mentioned order.
