Answer:

Scanner can be used to read tokens from the console window (user input)

Explanation:

Scanner is a class used in some programming languages to obtain inputs from users.

It is mostly well developed in Java programming language and used exclusively for taking and obtaining inputs.

Scanner takes input in primitive types such as doubles, floats and integers. IT also takes string inputs.

Here is a code snippet where the class scanner is used:

         Scanner input = new Scanner (System.in)

The code above creates an object of the scanner class

Write a test program that creates two Rectangle objects—one with width 4 and height 40 and the other with width 3.5 and height 3
BARSIC [14]

Answer:

public class Rectangle {

   private double width;

   private double heigth;

   public Rectangle(double width, double heigth) {

       this.width = width;

       this.heigth = heigth;

   }

   public double getWidth() {

       return width;

   }

   public void setWidth(double width) {

       this.width = width;

   }

   public double getHeigth() {

       return heigth;

   }

   public void setHeigth(double heigth) {

       this.heigth = heigth;

   }

   public double perimeter(double width, double heigth){

       double peri = 2*(width+heigth);

       return peri;

   }

   public double area(double width, double heigth){

       double area = width*heigth;

       return  area;

   }

}

class RectangleTest{

   public static void main(String[] args) {

       //Creating two Rectangle objects

       Rectangle rectangle1 = new Rectangle(4,40);

       Rectangle rectangle2 = new Rectangle(3.5, 35.7);

       //Calling methods on the first Rectangel objects

       System.out.println("The Height of Rectangle 1 is: "+rectangle1.getHeigth());

       System.out.println("The Width of Rectangle 1 is: "+rectangle1.getWidth());

       System.out.println("The Perimeter of Rectangle 1 is: "+rectangle1.perimeter(4,40));

       System.out.println("The Area of Rectangle 1 is: "+rectangle1.area(4,40));

       // Second Rectangle object

       System.out.println("The Height of Rectangle 2 is: "+rectangle2.getHeigth());

       System.out.println("The Width of Rectangle 2 is: "+rectangle2.getWidth());

       System.out.println("The Perimeter of Rectangle 2 is: "+rectangle2.perimeter(4,40));

       System.out.println("The Area of Rectangle 2 is: "+rectangle2.area(4,40));

   }

}

Explanation:

  • Firstly A Rectangle class is created with two fields for width and heigth, a constructor and getters and setters the class also has methods for finding area and perimeters
  • Then a RectangleTest class containing a main method is created and two Rectangle objects are created (Follow teh comments in the code)
  • Methods to get height, width, area and perimeter are called on each rectangle object to print the appropriate value

TV show information can either keep track of the number of viewers per show or the name of a show. Information is kept in a file
Elza [17]

Answer:

See explaination for Program source code.

Explanation:

The program source code below.

#include <iostream>

#include <fstream>

#include <vector>

using namespace std;

class Show

{

private:

string title;

int viewers;

public:

Show()

{

this->title = "";

this->viewers = 0;

}

Show(string title, int viewers)

{

this->title = title;

this->viewers = viewers;

}

string getTitle(){ return this->title; }

int getViewers(){ return this->viewers; }

};

int main()

{

vector<Show> shows;

vector<string> titles;

vector<int> viewers;

ifstream inFile1("file1.txt");

ifstream inFile2("file2.txt");

string line1, line2;

if(!inFile1.is_open() || !inFile2.is_open())

{

cout << "Either of the files could not be found!\n";

exit(0);

}

getline(inFile1, line1);

if(line1.compare("Show") == 0)

{

while(getline(inFile1, line1))

{

titles.push_back(line1);

}

inFile1.close();

}

getline(inFile2, line2);

if(line2.compare("Viewer") == 0)

{

while(getline(inFile2, line2))

{

viewers.push_back(stod(line2));

}

inFile2.close();

}

for(int i = 0; i < titles.size(); i++)

{

shows.push_back(Show(titles[i], viewers[i]));

}

// display all the show details

cout << "\nALL SHOWS:\n----------\n";

for(Show show : shows)

{

cout << "Title: " << show.getTitle() << ", Number of viewers: " << show.getViewers() << endl;

}

cout << endl;

return 0;

}
