Explanation:

The Book class and BookInformation class was not provided but was found online. After analyzing both of these classes I have created the following code that grabs and overrides the printInfo() method in order to add and print the edition and number of volumes as well

public class Encyclopedia extends Book {

   String edition;

   int numVolumes;

   public String getEdition() {

       return edition;

   }

   public void setEdition(String edition) {

       this.edition = edition;

   }

   public int getNumVolumes() {

       return numVolumes;

   }

   public void setNumVolumes(int numVolumes) {

       this.numVolumes = numVolumes;

   }

   public void printInfo() {

       System.out.println("Book Information: ");

       System.out.println(" Book Title: " + super.title);

       System.out.println(" Author: " + author);

       System.out.println(" Publisher: " + publisher);

       System.out.println(" Publication Date: " + publicationDate);

       System.out.println(" Edition: " + getEdition());

       System.out.println(" Number of Volumes: " + getNumVolumes());

   }

Answer:

The program in Python is as follows:

R1 = int(input("R1: "))

R2 = int(input("R2: "))

R3 = int(input("R3: "))

Rt = R1 + R2 + R3

Vs = int(input("Circuit Voltage: "))

It = Vs/Rt

V1= It * R1

V2= It * R2

V3= It * R3

print("The voltage drop across R1 is: ",V1)

print("The voltage drop across R2 is: ",V2)

print("The voltage drop across R3 is: ",V3)  

Explanation:

The next three lines get the value of each resistor

R1 = int(input("R1: "))

R2 = int(input("R2: "))

R3 = int(input("R3: "))

This calculates the total resistance    

Rt = R1 + R2 + R3

This prompts the user for Circuit voltage

Vs = int(input("Circuit Voltage: "))

This calculates the total circuit voltage

It = Vs/Rt

The next three line calculate the voltage drop for each resistor

V1= It * R1

V2= It * R2

V3= It * R3

The next three line print the voltage drop for each resistor

print("The voltage drop across R1 is: ",V1)

print("The voltage drop across R2 is: ",V2)

print("The voltage drop across R3 is: ",V3)

Answer: status bar

Explanation:

The status bar refers to the horizontal window that's found at the bottom of the parent window whereby an application will show different kinds of status information.

The main function of the status bar is to simply display information withnragrds to the current state of the window. Therefore, the status bar helps in the presentation of information about the document, indicates progress of

current tasks and also the status of some commands and keys.

Answer:

switch(inventory){

   case B || C:

       total_paper += paper_order;

       break;

   case D || F || E:

       total_ribbon += ribbon_order;

       break;

   case A || X:

       total_label += label_order;

       break;

   case M:

       break;

   default:

       console.log("Error! Invalid inventory value");

}

Explanation:

The switch keyword is a control statement used in place of the if-statement. It uses the 'case' and 'break' keywords to compare input values and escape from the program flow respectively. The default keyword is used to accommodate input values that do not match the compared values of the cases.

Answer:

The pseudocode is as follows:

Total_Hours = 0

Input Client_Name

Rate = 30.00

For days = 1 to 5

      Input Hours_worked

      Total_Hours = Total_Hours + Hours_Worked

Charges = Rate * Total_Hours

Print "Brianna Watt"

Print Client_Name

Print Total_Hours

Print Rate

Print Charges

Explanation:

This initializes the total hours worked to 0

Total_Hours = 0

This gets input for the client name

Input Client_Name

This initializes the standard rate to 30.00

Rate = 30.00

This iterates through the 5 days of work

For days = 1 to 5

This gets input for the hours worked each day

      Input Hours_worked

This calculates the total hours worked for the 5 days

      Total_Hours = Total_Hours + Hours_Worked

This calculates the total charges

Charges = Rate * Total_Hours

This prints the company name

Print "Brianna Watt"

This prints the client name

Print Client_Name

This prints the total hours worked

Print Total_Hours

This prints the standard rate

Print Rate

This prints the total charges

Print Charges

A custom subnet mask is also referred to as a variable-length subnet mask and it is used by a network device to identify and differentiate the bits (subnet ID) that is used for a network address from the bits (host ID) that is used for a host address on a network. Thus, it is typically used when subnetting or supernetting on a network.

Given the following data:

Since the IP address is Class B, there are 16 bits for the subnet ID (141.27) while 16 are for the host ID. Thus, the custom subnet mask in dotted-decimal notation is equal to 255.255.0.0.

2. The custom subnet mask would allow for four (4) subnets.

3. There are 16 host bits available on each subnet.

Answer:

Secondary storage is needed to keep programs and data long term. Secondary storage is non-volatile , long-term storage. Without secondary storage all programs and data would be lost the moment the computer is switched off.

External storage enables users to store data separately from a computer's main or primary storage and memory at a relatively low cost. It increases storage capacity without having to open up a system.

}

Explanation:

In the code provided, we are creating an array of size 6 to store integer values. The objective is to populate this array by taking input from the user for specific indexes chosen randomly.

To achieve this, we have defined two methods: populateArray and printArray.

The populateArray method takes an array as a parameter and fills it with values provided by the user. Here's how it works:

The printArray method is responsible for printing the contents of the array. It uses a for-each enhanced loop to iterate over each element in the array and prints its value.

**By separating the population and printing logic into separate methods, the code becomes more modular and easier to understand.**

Answer:

a. Callers can be screened even with blocked caller IDs.

Explanation:

Communication can be defined as a process which typically involves the transfer of information from one person (sender) to another (recipient), through the use of semiotics, symbols and signs that are mutually understood by both parties. Some of the most widely used communication channel or medium over the internet are an e-mail (electronic mail) and Voice over Internet Protocol (VoIP).

Voice over Internet Protocol (VoIP) is also known as IP Telephony and it's a type of communication technology which typically involves the use of broadband connection for the transmission of voice data between two or more people. Thus, it requires the use of internet enabled devices such as smartphones, computers, IP phones, etc.

Blocking a number with the VoIP technology prevents the blocked user from calling or contacting your line. However, you can still screen or carry out some investigations with respect to the blocked number through Voice over Internet Protocol (VoIP).

Hence, the statement which is true of Voice over Internet Protocol (VoIP) is that, callers can be screened even with blocked caller IDs.
