I got the question right.
Create a Department object which contains a name (String), budget (double), and an ArrayList of Employee objects. Each Employee object contains a FirstName (String). LastName(String), and an Address object. Each Address object contains a Street (String), Apartment (int), City (String), and State as a char array of length 2. The Apartment parameter is optional but the other three are mandatory! Ensure no Address object can be created that does not have them. Finally, create a test program that allows users to Add, Delete, Print, and Search the Employees of a Department.
Answer:
Explanation:
The following code is very long and is split into the 4 classes that were requested/mentioned in the question: Department, Employee, Address, and Test. Each one is its own object with its own constructor. Getters and Setters were not created since they were not requested and the constructor handles all of the variable creation. Address makes apartment variable optional by overloading the constructor with a new one if no argument is passed upon creation.
package sample;
import sample.Employee;
import java.util.ArrayList;
class Department {
String name = "";
double budget = 0;
ArrayList<Employee> employees = new ArrayList<>();
void Department(String name, double budget, ArrayList<Employee> employees) {
this.name = name;
this.budget = budget;
this.employees = employees;
}
}
------------------------------------------------------------------------------------------------------------
package sample;
public class Employee {
String FirstName, LastName;
Address address = new Address();
public void Employee(String FirstName, String LastName, Address address) {
this.FirstName = FirstName;
this.LastName = LastName;
this.address = address;
}
}
-------------------------------------------------------------------------------------------------------------
package sample;
class Address {
String Street, City;
int apartment;
char[] state;
public void Address(String street, String city, char[] state, int apartment) {
this.Street = street;
this.City = city;
this.state = state;
this.apartment = apartment;
}
public void Address(String street, String city, char[] state) {
this.Street = street;
this.City = city;
this.state = state;
this.apartment = 0;
}
}
-------------------------------------------------------------------------------------------------------------
package sample;
public class Test extends Department {
public void add(Department department, Employee employee) {
department.employees.add(employee);
}
public void delete(Department department, Employee employee) {
for (int x = 0; x < department.employees.size(); x++) {
if (department.employees.get(x) == employee) {
department.employees.remove(x);
}
}
}
public void Print(Department department, Employee employee) {
for (int x = 0; x < department.employees.size(); x++) {
if (department.employees.get(x) == employee) {
System.out.println(employee);
}
}
}
public void Search (Department department, Employee employee) {
for (int x = 0; x < department.employees.size(); x++) {
if (department.employees.get(x) == employee) {

How are BGP neighbor relationships formed
Automatically through BGP
Automatically through EIGRP
Automatically through OSPF
They are setup manually
Answer:
They are set up manually
Explanation:
BGP neighbor relationships formed "They are set up manually."
This is explained between when the BGP developed a close to a neighbor with other BGP routers, the BGP neighbor is then fully made manually with the help of TCP port 179 to connect and form the relationship between the BGP neighbor, this is then followed up through the interaction of any routing data between them.
For BGP neighbors relationship to become established it succeeds through various phases, which are:
1. Idle
2. Connect
3. Active
4. OpenSent
5. OpenConfirm

Explanation:
Create an array of doubles to contain 5 values Prompt the user to enter 5 values that will be stored in the array. These values represent hours worked. Each element represents one day of work. Create 3 c-strings: full[40], first[20], last[20] Create a function parse_name(char full[], char first[], char last[]). This function will take a full name such as "Noah Zark" and separate "Noah" into the first c-string, and "Zark" into the last c-string. Create a function void create_timecard(double hours[], char first[], char last[]). This function will create (write to) a file called "timecard.txt". The file will contain the parsed first and last name, the hours, and a total of the hours. See the final file below. First Name: Noah
Solution :

Write a SELECT statement that returns these columns from the Orders table: The CardNumber column The length of the CardNumber column The last four digits of the CardNumber columnWhen you get that working right, add the column that follows to the result set. This is more difficult because the column requires the use of functions within functions. A column that displays the last four digits of the CardNumber column in this format: XXXX-XXXX-XXXX-1234. In other words, use Xs for the first 12 digits of the card number and actual numbers for the last four digits of the number.selectCardNumber,len(CardNumber) as CardNumberLegnth,right(CardNumber, 4) as LastFourDigits,'XXXX-XXXX-XXXX-' + right(CardNumber, 4) as FormattedNumberfrom Orders
Answer:
SELECT
CardNumber,
len(CardNumber) as CardNumberLength,
right(CardNumber, 4) as LastFourDigits,
'XXXX-XXXX-XXXX-' + right(CardNumber, 4) as FormattedNumber
from Orders
Explanation:
The question you posted contains the answer (See answer section). So, I will only help in providing an explanation
Given
Table name: Orders
Records to select: CardNumber, length of CardNumber, last 4 digits of CardNumber
From the question, we understand that the last four digits should display the first 12 digits as X while the last 4 digits are displayed.
So, the solution is as follows:
SELECT ----> This implies that the query is to perform a select operation
CardNumber, ---> This represents a column to read
len(CardNumber) as CardNumberLength, -----> len(CardNumber) means that the length of card number is to be calculated.
as CardNumberLength implies that an CardNumberLength is used as an alias to represent the calculated length
right(CardNumber, 4) as LastFourDigits, --> This reads the 4 rightmost digit of column CardNumber
'XXXX-XXXX-XXXX-' + right(CardNumber, 4) as FormattedNumber --> This concatenates the prefix XXXX-XXXX-XXXX to the 4 rightmost digit of column CardNumber
as FormattedNumber implies that an FormattedNumber is used as an alias to represent record
from Orders --> This represents the table where the record is being read.

Suppose you decide to use the number of times you see any of the area codes of the places Yanay has been to in 50 spam calls as your test statistic. Question 7. Write a function called simulate_visited_area_codes that generates exactly one simulated value of your test statistic under the null hypothesis. It should take no arguments and simulate 50 area codes under the assumption that the result of each area is sampled from the range 200-999 inclusive with equal probability. Your function should return the number of times you saw any of the area codes of the places Yanay has been to in those 50 spam calls. Hint: You may find the textbook section on the sample_proportions function to be useful. For model_proportions, under the null hypothesis, what's the chance of drawing one of the area codes Yanay has recently been to
Answer:
In Python:
import random
def simulate_visited_area_codes():
area_codes = []
for i in range(51):
num = random.randint(200,1000)
area_codes.append(num)
visited_codes = [289, 657, 786, 540]
count = 0
for i in range(51):
for j in range(len(visited_codes)):
if area_codes[i] == visited_codes[j]:
count+=1
return count
print("Visited Areas: "+str(simulate_visited_area_codes()))
Explanation:
So many incomplete details in your question, so I will fill in the gap (i.e. make assumptions)
The assumptions are:
The 50 area codes is stored in area_codes list; the codes are randomly generatedThe visited area codes is stored in visited_codes list, the list is initializes with [289, 657, 786, 540]The program and explanation is as follows: (comments are written in bold)
#This imports the random module
import random
#This defines the function
def simulate_visited_area_codes():
#Thie initializes area_codes to an empty list
area_codes = []
#This iterates from 1 to 50 and generate 50 random numbers to the area_codes list
for i in range(51):
num = random.randint(200,1000)
area_codes.append(num)
#This initializes the visited_code
visited_codes = [289, 657, 786, 540]
#This initializes count variable to 0
count = 0
#This iterates through the list and looks for matching code between the area_code and the visited_code lists
for i in range(51):
for j in range(len(visited_codes)):
if area_codes[i] == visited_codes[j]:
#The count variable is incremented by 1 for matching codes
count+=1
#This returns the count
return count
#The main begins here and prints the number of area code visited
print("Visited Areas: "+str(simulate_visited_area_codes()))

. Suppose an instruction takes 1/2 microsecond to execute (on the average), and a page fault takes 250 microseconds of processor time to handle plus 10 milliseconds of disk time to read in the page. (a) How many pages a second can the disk transfer? (b) Suppose that 1/3 of the pages are dirty. It takes two page transfers to replace a dirty page. Compute the average number of instructions between page fault that would cause the system to saturate the disk with page traffic, that is, for the disk to be busy all the time doing page transfers.
Answer:
a. 100.
b. 31500.
Explanation:
So, we are given the following data which is going to help in solving this particular question.
The time required to execute (on the average) = 1/2 microsecond , a page fault takes of processor time to handle = 250 microseconds and the disk time to read in the page = 10 milliseconds.
Thus, the time taken by the processor to handle the page fault = 250 microseconds / 1000 = 0.25 milliseconds.
The execution time = [ 1/2 microseconds ]/ 1000 = 0.0005 milliseconds.
The number of Pages sent in a second by the disc = 1000/10 milliseconds = 100.
Assuming U = 1.
Hence, the disc transfer time = [2/3 × 1 } + [ 1/3 × 0.25 milliseconds + 15 ] × 2.
=0.667 + 15.083.
= 15.75 millisecond.
Average number of instruction = 15.75/0.0005 = 31500.
It should be noted that the number of pages in a second will be 100 pages.
From the information given, it was stated that the instruction takes 1/2 microsecond to execute and a page fault takes 250 microseconds of processor time to handle plus 10 milliseconds of disk time to read the page.
Therefore, the execution time will be:
= 0.5/1000
= 0.0005
Therefore, the number of pages will be:
= 1000/10
= 100
Also, the disc transfer time will be;
= (2/3 × 1) + (1/3 × 0.25 + 15) × 2
= 0.667 + 15.083
= 15.75
Therefore, the average number of instructions will be:
= 15.75/0.0005
= 31500

Goal: The campus squirrels are throwing a party! Do not ask. They need you to write a method that will determine whether it will be successfull (returns true) or not (returns false). The decision will be based on int values of the two parameters "squirrels" and "walnuts" representing respectively the number of squirrels attending the party and the numbers of walnuts available to them. The rules for making that determination are detailed below. Variables declarations & initialization: Boolean variable named "result", initialized to false. Steps for the code: First, if less than 1 squirrel attends, then "result" is assigned false. Else, we consider the following conditions: If we have less than, or exactly, 10 squirrels attending: Then: If we have less than 15 walnuts, Then: "result" is set to false. Else: if we have less than, or exactly, 30 walnuts Then: "result" is set to true. Else: "result" is set to false. Else: If less than, or exactly, 30 squirrels are attending Then: If the number of walnuts is more or equal to twice the number of squirrels attending Then: "result" is set to true Else: "result" is set to false Else: If the number of walnuts is equal to 60 plus the number of squirrels attending minus 30 Then: "result" is set to true Else: "result" is set to false
Answer:
Following are the code to the given question:
#include<iostream>// header file
using namespace std;
int main()//main function
{
int squirrels, walnuts;//defining integer variable
bool result = false; //defining a bool variable that holds a false value
cout<<"Enter the number of squirrels"<<endl;//print message
cin>>squirrels; // input integer value
cout<<"Enter the number of walnuts"<<endl;//print message
cin>>walnuts; // input integer value
if(squirrels < 1)//use if variable that checks squirrels value less than 1
{
result = false;//use result variable that holds false value
}
else//defining else block
{
if(squirrels <= 10)//use if variable that checks squirrels value less than equal to 10
{
if(walnuts < 15) //use if variable that checks walnuts value less than 15
result = false;//use result variable that holds false value
else if(walnuts <= 30)//use elseif block that checks walnuts less than equal to 30
result = true; //use result variable that holds true value
else //defining else block
result = false;//use result variable that holds false value
}
else if(squirrels <= 30)//use elseif that checks squirrels value less than equal to 30
{
if(walnuts >= 2*squirrels) //use if block to check walnuts value greater than equal to 2 times of squirrels
result = true; //use result variable that holds true value
else//defining else block
result = false;//use result variable that holds false value
}
else if(walnuts == 60 + squirrels - 30)//using elseif that checks walnuts value equal to squirrels
result = true;//use result variable that holds true value
else //defining else block
result = false;//use result variable that holds false value
}
if(result)//use if to check result
cout<<"True";//print True as a message
else //defining else block
cout<<"False";//print False as a message
return 0;
}
Output:
Enter the number of squirrels

Suppose you design a banking application. The class CheckingAccount already exists and implements interface Account. Another class that implements the Account interface is CreditAccount. When the user calls creditAccount.withdraw(amount) it actually makes a loan from the bank. Now you have to write the class OverdraftCheckingAccount, that also implements Account and that provides overdraft protection, meaning that if overdraftCheckingAccount.withdraw(amount) brings the balance below 0, it will actually withdraw the difference from a CreditAccount linked to the OverdraftCheckingAccount object. What design pattern is appropriate in this case for implementing the OverdraftCheckingAccount class
Answer:
Strategy
Explanation:
The strategic design pattern is defined as the behavioral design pattern that enables the selecting of a algorithm for the runtime. Here the code receives a run-time instructions regarding the family of the algorithms to be used.
In the context, the strategic pattern is used for the application for implementing OverdraftCheckingAccount class. And the main aspect of this strategic pattern is the reusability of the code. It is behavioral pattern.
Chris recently received an array p as his birthday gift from Joseph, whose elements are either 0 or 1. He wants to use it to generate an infinite long superarray. Here is his strategy: each time, he inverts his array by bits, changing all 0 to 1 and all 1 to 0 to get another array, then concatenate the original array and the inverted array together. For example, if the original array is [0,1,1,0] then the inverted array will be [1,0,0,1] and the new array will be [0,1,1,0,1,0,0,1]. He wonders what the array will look like after he repeat this many many times.
He ask you to help him sort this out. Given the original array pp of length ????n and two indices a,b (????≪????≪????, means much less than) Design an algorithm to calculate the sum of elements between a and b of the generated infinite array p^, specifically, ∑????≤????≤????p????^. He also wants you to do it real fast, so make sure your algorithm runs less than O(b) time. Explain your algorithm and analyze its complexity.
