$4.50; product 3, $9.98; product 4, $4.49 and product 5, $6.87. Write an application that reads a series of pairs of numbers as follows: product number quantity sold Your program should use a switch statement to determine the retail price for each product. It should calculate and display the total retail value of all products sold. Use a sentinel-controlled loop to determine when the program should stop looping and display the final results.

Answer:

import java.util.Scanner;

public class Main

{

public static void main(String[] args) {

   

    //Initialize the prices as constants

    final double PRODUCT_1_PRICE = 2.98;

    final double PRODUCT_2_PRICE = 4.50;

    final double PRODUCT_3_PRICE = 9.98;

    final double PRODUCT_4_PRICE = 4.49;

    final double PRODUCT_5_PRICE = 6.87;

   

    //Declare the other variables

    int productNumber, quantitySold;

    double total = 0.0;

   

    //Create a Scanner object to get input

    Scanner input = new Scanner(System.in);

   

    //Create a while loop

    while(true){

        //Ask the user to enter the productNumber

     System.out.print("Enter the product number or 999 to quit: ");

     productNumber = input.nextInt();

     

     // Stop the loop, if productNumber is 999(sentinel value, you may choose any value you want)

     if(productNumber == 999)

         break;

     

     //Ask the user to enter the quantitySold

     System.out.print("Enter the quantity sold: ");

     quantitySold = input.nextInt();

     

     //Create a switch statement that works depending on the productNumber entered.

     //For example, if the productNumber is 1, it multiplies the quantitySold by PRODUCT_1_PRICE

     //   and adds the result to the total. If productNumber is 2, it does the same for product 2 ...

     switch(productNumber){

         case 1:

             total += quantitySold * PRODUCT_1_PRICE;

             break;

         case 2:

             total += quantitySold * PRODUCT_2_PRICE;

             break;

         case 3:

             total += quantitySold * PRODUCT_3_PRICE;

             break;

         case 4:

             total += quantitySold * PRODUCT_4_PRICE;

             break;

         case 5:

             total += quantitySold * PRODUCT_5_PRICE;

             break;

     }

    }

 

 //Print the total (when the loop is done)

 System.out.println("The total is $" + total);

}

}

Select the proper ergonomic keyboarding techniques.
SCORPION-xisa [38]

Answer:

The correct options are;

-Position the keyboard directly in front and close to you so you don't have an excessive reach

-Keep your shoulders, arms, hands and fingers relaxed

-Position your wrists straight or in neutral position while typing

-Adjust your chair height and position so your feet rest flat on the floor, or add a footrest to compensate for a higher chair

-Adjust the keyboard height so that your shoulders can relax and your arms are straight in front of you

Explanation:

1) It is important to keep the fingers in a relaxed position when typing

2) Ensure to type in a tapping fashion when typing rather than pressing on the keys of the keyboard

3) The fingernails should be kept short when frequent typing is done

4) The wrist is better kept above the keyboard than resting on it

5) Ensure that the mouse is easily reached.

What programming language supports relational databases?
WINSTONCH [101]

A programming language that supports relational databases is SQL (Structured Query Language)

Structured Query Language (SQL), is the principal method for communicating with Relational Databases.

A relational database is a group of data elements that are linked together by predefined connections. These elements are laid up in the form of a series of tables containing columns and rows.

  • Tables are utilized for storing data about the items that will be displayed in the database.
  • A column in a database contains a specific type of data, whereas a field records the actual value of an attribute.
  • The table's rows indicate a collection of linked values for a single item or entity.

Each entry in a database can be assigned a unique identity known as a primary key, and rows from other tables can be linked together via foreign keys. This data may be accessible in a variety of ways without having to reorganize the database tables itself.

Assume that speed = 10 and miles = 5. What is the value of each of the
Assoli18 [71]

a. speed + 12 - miles * 2  = 10 + 12 - 5 * 2. With order of operations, we do the multiplication first so the equation is now 10 + 12 - 10 = 22 - 10 = 12

b. speed + miles * 3  = 10 + 5 * 3 and again, order of operations gives us 10 + 15 = 25

c. (speed + miles) * 3  = (10 + 5) * 3 = 15 * 3 = 45

d. speed + speed * miles + miles  = 10 + 10 * 5 + 5 = 10 + 50 + 5 = 60 + 5 = 65

e. (10 – speed) + miles / miles = (10 - 10) + 5 / 5 = 0 + 5 / 5 = 5 / 5 = 1
