Design 3 classes: Computer - Superclass
Laptop - Subclass
Desktop - Subclass
You will design these classes to optimize the superclass/subclass relationship by creating instance variables and getter/setter methods.
Include the following instance variables:
int screenSize -
Inches of monitor space
int memory - GB of ram
double batteryLife - Hours of battery life
boolean monitor - Whether or not a monitor is included
Each class should have at least one variable in it.
Once completed, the Tester class should execute without error.
Answers
Answer:
Explanation:
The following code is written in Java. It creates the three classes mentioned and a Tester class that contains the main method. The Computer class contains the memory variable since both laptops and Desktops need memory. The screen size variable is placed separately in the Laptop and Desktop class since desktops may or may not have a monitor so this variable cannot be placed in the Computer class. The batteryLife variable is only in the Laptop class because Desktops do not have batteries. Finally, the monitor variable is only placed in the Desktop class since Laptop's come with built-in monitors. The tester class seen in the picture below tests the creation of both of these objects and it executes without any error.
class Computer {
int memory;
public int getMemory() {
return memory;
}
public void setMemory(int memory) {
this.memory = memory;
}
}
class Laptop extends Computer {
int screenSize;
double batteryLife;
public int getScreenSize() {
return screenSize;
}
public void setScreenSize(int screenSize) {
this.screenSize = screenSize;
}
public double getBatteryLife() {
return batteryLife;
}
public void setBatteryLife(double batteryLife) {
this.batteryLife = batteryLife;
}
}
class Desktop extends Computer {
boolean monitor;
int screenSize;
public boolean isMonitor() {
return monitor;
}
public void setMonitor(boolean monitor) {
this.monitor = monitor;
}
public int getScreenSize() {
return screenSize;
}
public void setScreenSize(int screenSize) {
this.screenSize = screenSize;
}
}
class Tester {
public static void main(String[] args) {
Laptop computer1 = new Laptop();
Desktop computer2 = new Desktop();

The XYZ daycare has installed a new high-tech system for keeping track of which children are under its supervision at any moment in time. Each parent of a child has a card with a unique ID, where the ID is some integer x. Every morning, the parent swipes the card at a card-reader when dropping their child off at the daycare. The system then adds x to an array of integers. In the evening, when the parent comes to pick up the child, the same card is swiped, and a second copy of x is added to the list. Each night at midnight, the array is wiped clean and reset to have zero elements. In this way, the daycare can quickly check every afternoon which children are yet to be picked up by their parents by picking out the array elements that occur precisely once. Unfortunately, at 4:55 pm on Thursday, April 20, 2017, the daycare realizes that somewhere in their daycare is precisely one child who is yet to be picked up. Can you help them determine the integer ID of this child

The change in complex systems can be explained according to the relationship of the environment where the system is implemented.
The system environment is dynamic, which consequently leads to adaptation to the system, which generates new requirements inherent to changes in business objectives and policies. Therefore, changing systems is necessary for tuning and usefulness so that the system correctly supports business requirements.

Which of the following is a form of media?Check all that apply.
A. a brochure distributed to many people
B. a diary
C. an email to a friend
D. a blog
Answers
Answer:
A. a brochure distributed to many people.
D. a blog.
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.
Generally, the linear model of communication comprises of four (4) main components and these are;
1. Sender (S): this is typically the source of information (message) or the originator of a message that is being sent to a receiver. Thus, they are simply the producer of a message.
2. Channel (C): this is the medium used by the sender for the dissemination or transmission of the message to the recipient. For example, telephone, television, radio, newspapers, billboards etc.
3. Message (M): this is the information or data that is being sent to a recipient by a sender. It could be in the form of a video, audio, text message etc.
4. Receiver (R): this is typically the destination of information (message) or the recipient of a message that is being sent from a sender.
Hence, the following are forms of media (communication channel);
I. A brochure distributed to many people. It comprises of printed textual informations used mainly for promotional purposes.
II. A blog. It is an online website that contains both textual and multimedia messages, especially as a news platform.

You plan to make a delicious meal and want to take the money you need to buy the ingredients. Fortunately you know in advance the price per pound of each ingredient as well as the exact amount you need. The program should read in the number of ingredients (up to a maximum of 10 ingredients), then for each ingredient the price per pound. Finally your program should read the weight necessary for the recipe (for each ingredient in the same order). Your program should calculate the total cost of these purchases, then display it with 6 decimal places.
Example There are 4 ingredients and they all have a different price per pound: 9.90, 5.50, 12.0, and 15.0. You must take 0.25 lbs of the first, 1.5 lbs of the second, 0.3 lbs of the third and 1 lb of the fourth. It will cost exactly $29.325000.
Answers
Answer:
In Python:
prices = []
pounds = []
print("Enter 0 to stop input")
for i in range(10):
pr = float(input("P rice: "+str(i+1)+": "))
pd = float(input("Pound: "+str(i+1)+": "))
if pr != 0 and pd != 0:
prices.append(pr)
pounds.append(pd)
else:
break
amount = 0
for i in range(len(pounds)):
amount+= (pounds[i]*prices[i])
print("Amount: $",amount)
Explanation:
These initialize the prices and pounds lists
prices = []
pounds = []
This prompts the user to enter up to 10 items of press 0 to quit
print("Enter 0 to stop input")
This iterates through all inputs
for i in range(10):
This gets the price of each item
pr = float(input("P rice: "+str(i+1)+": "))
This gets the pound of each item
pd = float(input("Pound: "+str(i+1)+": "))
If price and pound are not 0
if pr != 0 and pd != 0:
The inputs are appended to their respective lists
prices.append(pr)
pounds.append(pd)
If otherwise, the loop is exited
else:
break
This initializes total to 0
amount = 0
This iterates through all inputs
for i in range(len(pounds)):
This multiplies each pound and each price and sum them up
amount+= (pounds[i]*prices[i])
The total is then printed
print("Amount: $",amount)

Course Project Part 4: Conducting the Experiment and Recording Data
After much preparation, you are finally ready to begin conducting your experiment. Due to all the hard work you put into your literature review and planning your procedures, the steps that you need to take to conduct your experiment successfully have already been set. While you conduct your experiment, you will need to keep a daily journal where you record the activities you undertake that are relevant to the experiment and also where you record any data that you collect. This is your experiment log and serves as a record of your work while also allowing you to make a record of any changes or modifications you may need to make during the experiment.
Conducting the Experiment and Keeping an Experiment Journal
Following the procedure that you established in the previous part of this project, set up your experiment and begin running it. Every day while your experiment is running you will make an entry in your journal. Record what activities you completed (refer to your outlined procedure to make sure you are following the procedure that you established), any modifications that had to be made to your set up or procedure, and any observations or data you collect. Even on days when you do not collect data (depending on your experiment, there may not be data collection every day), make an entry in your journal. Each journal entry should be clearly labeled with the date on which it was entered. You do not need to type up all your entries, but make sure that your journal entries are neatly written, as they will be evaluated by your instructor.
Depending on the topic and design of your experiment, the period of time during which you conduct and record your experiment may range from one to several weeks. In consultation with your instructor, you will establish a timeline for the evaluation of your journal. If you are running a shorter experiment, your journal may be evaluated several times over the course of one or two weeks. If your experiment takes longer to complete, you may have a weekly review over the course of a month. Follow the guidelines provided by your instructor.
Collecting Data
All experiments generate data. This data allows the scientist to evaluate the success of the experiment and make interpretations about the results generated by the investigation. When you record your data, you must collect it as consistently as possible. Returning to the plant experiment, it would be best to measure the plants on a set schedule. For example, you might choose to measure the plants every Thursday at 3 pm. It is important to measure the plants at the same time each week so that the difference in growth you might observe is a reflection of the experimental condition, not simply longer growing time. Additionally, it is important to use the same instruments to collect data. The plants should be measured with the same ruler or measuring tape each time. This helps reduce any error or bias that might be introduced by using different instruments to make measurements. Whatever measurements or data you collect, do so in a consistent manner. Use the same instruments, the same scales, and record the data in a standardized manner. It is also a good idea to record your experiment using photographs. This will help you later during analysis and provides information for others who might be interested in recreating your experiment. Record your data in your experiment journal, where it will be reviewed by your teacher on an on-going basis. Submit your journal to your instructor according to the schedule you have established together.

Write a program that will filter a list of non-negative integers such that all duplicate values are removed. Integer values will come from standard input (the keyboard) and will range in value from 0 up to 2,000,000,000. Input will be terminated by the special value, -1. Once the input is read in you should output (to the screen) the list of numbers as a sorted list (smallest to largest) with one value listed per line where all duplicates have been removed. The primary difficulty with this program is that there are an enormous number of input values and an expected large number of duplicate numbers.
Answers
Answer:
The program in python is as follows:
original = []
inp = int(input(": "))
while inp>=0:
if inp<=2000000000:
original.append(inp)
inp = int(input(": "))
newlist = []
for i in original:
if i not in newlist:
newlist.append(i)
newlist.sort()
for i in newlist:
print(i)
Explanation:
This initializes the original list
original = []
This gets input for the list
inp = int(input(": "))
The following loop is repeated while input is not negative
while inp>=0:
This ensures that only inputs from 0 and 2000000000 enters the list
if inp<=2000000000:
original.append(inp)
Prompt the user for another input
inp = int(input(": "))
This initializes a newlist
newlist = []
Iterates through the original list
for i in original:
Check for duplicate
if i not in newlist:
Each number is entered to the new list, without duplicate
newlist.append(i)
This sorts the new list in ascending order
newlist.sort()
This prints the list item one per line
for i in newlist:
print(i)
