Consider the definition of the Person class below. The class uses the instance variable adult to indicate whether a person is an adult or not.
public class Person
{
private String name;
private int age;
private boolean adult;
public Person (String n, int a)
{
name = n;
age = a;
if (age >= 18)
{
adult = true;
}
else
{
adult = false;
}
}
}
Which of the following statements will create a Person object that represents an adult person?
a. Person p = new Person ("Homer", "adult");
b. Person p = new Person ("Homer", 23);
c. Person p = new Person ("Homer", "23");
d. Person p = new Person ("Homer", true);
e. Person p = new Person ("Homer", 17);
Answer:
b. Person p = new Person ("Homer", 23);
Explanation:
The statement that will create an object that represents an adult person would be the following
Person p = new Person ("Homer", 23);
This statement creates a Person object by called the Person class and saving it into a variable called p. The Person method is called in this object and passed a string that represents the adult's name and the age of the adult. Since the age is greater than 18, the method will return that adult = true.
The other options are either not passing the correct second argument (needs to be an int) or is passing an int that is lower than 18 meaning that the method will state that the individual is not an adult.
g n this program, you will prompt the user for three numbers. You need to check and make sure that all numbers are equal to or greater than 0 (can use an if or if/else statement for this). You will then multiply the last two digits together, and add the result to the first number. The program should then start over, once again asking for another three numbers. This program should loop indefinitely in this way. If the user enters a number lower than 0, remind the user that they need to enter a number greater than or equal to 0 and loop the program again.
Answer:
In Python:
loop = True
while(loop):
nm1 = float(input("Number 1: "))
nm2 = float(input("Number 2: "))
nm3 = float(input("Number 3: "))
if (nm1 >= 0 and nm2 >= 0 and nm3 >= 0):
result = nm2 * nm3 + nm1
print("Result: "+str(result))
loop = True
else:
print("All inputs must be greater than or equal to 0")
loop = True
Explanation:
First, we set the loop to True (a boolean variable)
loop = True
This while loop iterates, indefinitely
while(loop):
The next three lines prompt user for three numbers
nm1 = float(input("Number 1: "))
nm2 = float(input("Number 2: "))
nm3 = float(input("Number 3: "))
The following if condition checks if all of the numbers are greater than or equal to 0
if (nm1 >= 0 and nm2 >= 0 and nm3 >= 0):
If yes, the result is calculated
result = nm2 * nm3 + nm1
... and printed
print("Result: "+str(result))
The loop is then set to true
loop = True
else:
If otherwise, the user is prompted to enter valid inputs
print("All inputs must be greater than or equal to 0")
The loop is then set to true
loop = True

III. Drift Layout.
Generally, end users are able to print a hard copy (physical copy) of the word document they created through the use of a printer.
In this scenario, Stacy plans to print her contacts and would like to choose an option that will print select information for each contact in a business card format. Therefore, the option she should choose is Card style.
The Card style is designed to present informations in a grid-like format or landscape arrangement.
We have looked at several basic design tools, such as hierarchy charts, flowcharts, and pseudocode. Each of these tools provide a different view of the design as they work together to define the program. Explain the unique role that each design tool provides (concepts and/or information) to the design of the program.
Answer:
Answered below
Explanation:
Pseudocode is a language that program designers use to write the logic of the program or algorithms, which can later be implemented using any programming language of choice. It helps programmers focus on the logic of the program and not syntax.
Flowcharts are used to represent the flow of an algorithm, diagrammatically. It shows the sequence and steps an algorithm takes.
Hierarchy charts give a bird-eye view of the components of a program, from its modules, to classes to methods etc.

Explanation:
You've created a new programming language, and now you've decided to add hashmap support to it. Actually you are quite disappointed that in common programming languages it's impossible to add a number to all hashmap keys, or all its values. So you've decided to take matters into your own hands and implement your own hashmap in your new language that has the following operations:
insert x y - insert an object with key x and value y.
get x - return the value of an object with key x.
addToKey x - add x to all keys in map.
addToValue y - add y to all values in map.
To test out your new hashmap, you have a list of queries in the form of two arrays: queryTypes contains the names of the methods to be called (eg: insert, get, etc), and queries contains the arguments for those methods (the x and y values).
Your task is to implement this hashmap, apply the given queries, and to find the sum of all the results for get operations.
Example
For queryType = ["insert", "insert", "addToValue", "addToKey", "get"] and query = [[1, 2], [2, 3], [2], [1], [3]], the output should be hashMap(queryType, query) = 5.
The hashmap looks like this after each query:
1 query: {1: 2}
2 query: {1: 2, 2: 3}
3 query: {1: 4, 2: 5}
4 query: {2: 4, 3: 5}
5 query: answer is 5
The result of the last get query for 3 is 5 in the resulting hashmap.
For queryType = ["insert", "addToValue", "get", "insert", "addToKey", "addToValue", "get"] and query = [[1, 2], [2], [1], [2, 3], [1], [-1], [3]], the output should be hashMap(queryType, query) = 6.
The hashmap looks like this after each query:
1 query: {1: 2}
2 query: {1: 4}
3 query: answer is 4
4 query: {1: 4, 2: 3}
5 query: {2: 4, 3: 3}
6 query: {2: 3, 3: 2}
7 query: answer is 2
The sum of the results for all the get queries is equal to 4 + 2 = 6.

A customer comes into a grocery store and buys 8 items. Write a PYTHON program that prompts the user for the name of the item AND the price of each item, and then simply displays whatever the user typed in on the screen nicely formatted. Some example input might be: Apples 2.10 Hamburger 3.25 Milk 3.49 Sugar 1.99 Bread 1.76 Deli Turkey 7.99 Pickles 3.42 Butter 2.79 Remember - you will be outputting to the screen - so do a screen capture to turn in your output. Also turn in your PYTHON program code.
Answer:
name = []
price = []
for i in range(0,8):
item_name = input('name of item')
item_price = input('price of item')
name.append(item_name)
price.append(item_price)
for i in range(0, 8):
print(name[i], '_____', price[i])

A perpetual system of inventory can be defined as a method of financial accounting, which involves the updating informations about an inventory on a continuous basis (in real-time) as the sales or purchases are being made by the customers, through the use of enterprise management software applications and a digitized point-of-sale (POS) equipment.
Under a perpetual system of inventory, updates of the journal entry for cost of goods sold or received would include debiting accounts receivable and crediting sales immediately as it is being made or happening.
Hence, an advantage of the perpetual system of inventory over the periodic system of inventory is that, it ensures the inventory account balance is always accurate provided there are no spoilage, theft etc.
The following are the characteristic of a perpetual inventory system;
I. It is the most popular choice for modern business.
II. Inventory is updated in near real-time.
III. It provides up-to-date balance information and requires fewer physical counts.

Explanation:
magine that you are designing an application where you need to perform the operations Insert, DeleteMaximum, and Delete Minimum. For this application, the cost of inserting is not important, because itcan be done off-line prior to startup of the time-critical section, but the performance of the two deletionoperations are critical. Repeated deletions of either kind must work as fast as possible. Suggest a datastructure that can support this application, and justify your suggestion. What is the time complexity foreach of the three key operations
Answer:
Use the stack data structure with both best-case and worst-case time complexity of O(1) for insertion and deletion of elements.
Explanation:
The stack data structure is used in programs to hold data for which the last data in the stack is always popped out first when retrieving the data sequentially, that it, first-in, last-out.
The elements in the stack are located in an index location, which means that they can be retrieved directly by choice with constant time complexity of 1 or O(1) for best and worst-case.
So inserting, and deleting the minimum and maximum elements in the stack data structure executes at a speed of the constant 1 (big-O notation, O(1) ).

numC =
Answer: 3
Explanation:
What is the value of numC at the end of this loop?
numC = 12
while numC > 3:
numC = numC / 2
numC =
The initial numC value = 12
Condition : while numC is greater than 3 ; 12 > 3 (condition met)
The expression numC / 2 is evaluated
numC / 2 = 12 / 2 = 6
numC then becomes 6 ;
Condition : while numC is greater than 3 ; 6 > 3 (condition met)
numC / 2 = 6 /2 = 3
numC = 3
Condition : while numC is greater than 3 ; 3 > 3 (condition not met)
Loop terminates
numC = 3
In the following code segment, assume that the ArrayList numList has been properly declared and initialized to contain the Integer values [1, 2, 2, 3]. The code segment is intended to insert the Integer value val in numList so that numList will remain in ascending order. The code segment does not work as intended in all cases.
int index = 0;
while (val > numList.get(index))
{
index++;
}
numList.add(index, val);
For which of the following values of val will the code segment not work as intended?
a. 0
b. 1
c. 2
d. 3
e. 4
Answer:
e. 4
Explanation:
The code segment will not work as intended if the value of the variable val is 4. This is because the while loop is comparing the value of the variable val to the value of each element within the numList. Since there is no element that is bigger than or equal to the number 4, this means that if the variable val is given the value of 4 it will become an infinite loop. This would cause the program to crash and not work as intended.
The program illustrates the use of while loops.
The code segment will not work as intended when the value of val is 4
LoopsLoops are used to perform repeated operations
The programFrom the program, the while loop is repeated under the following condition:
val > numList.get(index)
This means that:
The loop is repeated as long as val has a value greater than the index of numList (i.e. 3)
From the list of options, 4 is greater than 3.
Hence, the code segment will not work as intended when the value of val is 4

Write a function called is_present that takes in two parameters: an integer and a list of integers (NOTE that the first parameter should be the integer and the second parameter should be the list) and returns True if the integer is present in the list and returns False if the integer is not present in the list. You can pick everything about the parameter name and how you write the body of the function, but it must be called is_present. The code challenge will call your is_present function with many inputs and check that it behaves correctly on all of them. The code to read in the inputs from the user and to print the output is already written in the backend. Your task is to only write the is_present function.
Answer:
The function in python is as follows
def is_present(num,list):
stat = False
if num in list:
stat = True
return bool(stat)
Explanation:
This defines the function
def is_present(num,list):
This initializes a boolean variable to false
stat = False
If the integer number is present in the list
if num in list:
This boolean variable is updated to true
stat = True
This returns true or false
return bool(stat)

Answer:
A. Computing devices translate digital to analog information in order to process the information.
Explanation:
Computing is the process of using computer hardware and software to manage, process and transmit data in order to complete a goal-oriented task.
The true statements about computers are;
I. Computing devices are electronic: the components and parts which makes up a computer system are mainly powered by a power supply unit and motherboard that typically comprises of electronic components such as capacitors, resistors, diodes etc.
II. The CPU processes commands: the central processing unit (CPU) is responsible for converting or transforming the data from an input device into a usable format and sent to the output device.
III. The memory uses binary numbers: computer only understand ones and zeros.
Write a program named BinaryToDecimal.java that reads a 4-bit binary number from the keyboard as a string and then converts it into decimal. For example, if the input is 1100, the output should be 12. (Hint: break the string into substrings and then convert each substring to a value for a single bit. If the bits are b0, b1, b2, b3, then decimal equivalent is 8b0 4b1 2b2 b3)
Answer:
import java.util.*;
public class BinaryToDecimal
{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String binaryNumber;
int decimalNumber = 0;
System.out.print("Enter the binary number: ");
binaryNumber = input.nextLine();
for(int i=0; i<binaryNumber.length(); i++){
char c = binaryNumber.charAt(binaryNumber.length()-1-i);
int digit = Character.getNumericValue(c);
decimalNumber += (digit * Math.pow(2, i));
}
System.out.println(decimalNumber);
}
}
Explanation:
Create a Scanner object to be able to get input from the user
Declare the variables
Ask the user to enter the binaryNumber as a String
Create a for loop that iterates through the binaryNumber. Get each character using charAt() method. Convert that character to an integer value using Character.getNumericValue(). Add the multiplication of integer value and 2 to the power of i to the decimalNumber variable (cumulative sum)
When the loop is done, print the decimalNumber variable
What is the relationship between an object and class in an OOP program?
The object contains classes.
The object and class are the same thing.
The object is used to create a class.
The object in a program is called a class.
Answer:
D. The object in a program is called a class.
Explanation:
Java is a object oriented and class-based programming language. It was developed by Sun Microsystems on the 23rd of May, 1995. Java was designed by a software engineer called James Gosling and it is originally owned by Oracle.
In object-oriented programming (OOP) language, an object class represents the superclass of every other classes when using a programming language such as Java. The superclass is more or less like a general class in an inheritance hierarchy. Thus, a subclass can inherit the variables or methods of the superclass.
Basically, all instance variables that have been used or declared in any superclass would be present in its subclass object.
Hence, the relationship between an object and class in an OOP program is that the object in a program is called a class.
For example, if you declare a class named dog, the objects would include barking, color, size, breed, age, etc. because they are an instance of a class and as such would execute a method defined in the class.

Follows are the code to this question:
def dic_sorted(data):#defining a method print_dic_sorted

d = {} #defining a dictionary
alpha = '0123456789abcdefghijklmnopqrstuvwxyz' #defining a variable alpha that hold english alphabets values
for k in alpha:#defining for loop that stores values in the dictionary
d[k]= set()# use dictionary to set value in list
for i in s:# defining for loop to convert value in lower case
i = i.lower() #convert value into lower case by using lower method
a = i[0]# adding value into dictionary
d[a].add(i) # use add method to hold value in dictionary
for k,v in sorted(d.items()):#use for loop to convert value in assending order
if len(d[k])!=0: #use if block to check length of dictionary

with open(f_name) as fi:#use open method to read file
data = fi.read() # read file data
dic_sorted(data)#calling method
output:
please find the attached file.
Explanation:
In the code, the "dic_sorted" method is used, which accepts a data variable as a parameter, and inside the method, a split method and an empty dictionary are defined, that converts and holds the value by alphabetical order, for this it defines three for loops.
In the first for loop, it holds a value in the dictionary, and in the second loop it converts a value into the lower case, and in the third loop, it stores the value in its alphabetical order.
