JavaFX application for the Sublime Sandwich Shop. The user can order sandwiches by using list boxes and the application displays the price. Each sandwich should allow a choice of at least three main ingredients (chicken, for example) at three different prices. The user should also be able to choose between three different bread types. Use CheckBoxes for additional ingredients - lettuce, tomato, etc.
Create an ArrayList to hold all of the sandwiches associated with an order. Display information about all the sandwiches that were ordered.

Write a program that accepts the lengths of three sides of a triangle as an input from the user: A, B, C
Validate the user input so that the user can only enter positive values for sides A, B, C. All three must be true:
A > 0
B > 0
C > 0
Answer:
The program in Python is as follows:
A = int(input("A: "))
B = int(input("B: "))
C = int(input("C: "))
while A<=0 or B <= 0 or C <= 0:
A = int(input("A: "))
B = int(input("B: "))
C = int(input("C: "))
print("Valid inputs")
Explanation:
Get input for A, B and C
A = int(input("A: "))
B = int(input("B: "))
C = int(input("C: "))
The loop is repeated until inputs for A, B and C are above 0
while A<=0 or B <= 0 or C <= 0:
Get input for A, B and C
A = int(input("A: "))
B = int(input("B: "))
C = int(input("C: "))
Print valid inputs when user inputs are correct
print("Valid inputs")

Write a program get_price.py with a function get_price() that takes a dictionary of fruits as an argument and returns the name of the most expensive fruit. Each item of the dictionary includes: A key: the name of the fruit A value: the price of the fruit.
Answer:
The program is as follows:
def get_price(fruits):
AllPrice = fruits.values()
value_iterator = iter(AllPrice)
mostExpensive = next(value_iterator)
for item in fruits:
if fruits[item]>=mostExpensive:
mostExpensive = fruits[item]
fruitName = item
print(fruitName)
fruits = {}
n = int(input("Number of Fruits: "))
for i in range(n):
name = input("Fruit name: ")
price = int(input("Fruit price: "))
fruits[name] = price
get_price(fruits)
Explanation:
This defines the get_price function
def get_price(fruits):
This gets all price in the dictionary fruit
AllPrice = fruits.values()
This passes the values to a value iterator
value_iterator = iter(AllPrice)
This initializes mostExpensive to the first price in the dictionary
mostExpensive = next(value_iterator)
This iterates through the elements of the dictionary
for item in fruits:
If current element is greater than or equals most expensive
if fruits[item]>=mostExpensive:
Set most expensive to the current element
mostExpensive = fruits[item]
Get the corresponding fruit name
fruitName = item
Print fruit name
print(fruitName)
The main begins here
This initializes the fruit dictionary
fruits = {}
This gets input for the number of fruits
n = int(input("Number of Fruits: "))
This is repeated for every inputs
for i in range(n):
Get fruit name
name = input("Fruit name: ")
Get fruit price
price = int(input("Fruit price: "))
Append name and price to dictionary
fruits[name] = price
Call the get_price function
get_price(fruits)

ISPs
Answer:
Routers
Explanation:
Essentially a router is a device used in networking that route packets of data from one computer network to another.
Answer:
routers
Explanation:
Routers are hardware devices that route the data from place to place. Data "hops" from one router to another until it reaches its destination. ISPs and IP addresses are not hardware devices. Servers are hardware devices but do not route data.

Peter is a new business owner. Because Peter is on a strict budget, he uses an older Novell NetWare server. The NetWare server still relies on the legacy IPX/SPX network protocol suite. Peter needs to connect his server to the Internet. He decides to use a gateway instead of a router. What is the likely motive behind Peter's decision
The most likely motive of Peter's decision to use a gateway for connecting his serve to the internet is to get a wireless connection for the internet.
A gateway server is used to communicate to the internet service provider. It is used to receives the data. It helps to sends the data to the router in order to translate as well as distribute the wireless devices.
In the context, Peter who is on a strict budget uses gateway system to connect to the internet and he uses the older version of Novell NetWare server.

3. Write a program that prompts the user to input an integer that represents cents. The program will then calculate the smallest combination of coins that the user has. For example, 27 cents is 1 quarter, 0 nickle, and 2 pennies. That is 27=1*25+0*5+2*1.
Answer:
The program in Python is as follows:
cents = int(input("Cents: "))
qtr = int(cents/25)
cents = cents -qtr * 25
nkl = int(cents/5)
pny = cents -nkl * 5
print(qtr,"quarters,",nkl,"nickels,",pny,"pennies")
Explanation:
This gets input for cents
cents = int(input("Cents: "))
This calculates the quarters in cents
qtr = int(cents/25)
This gets the remaining cents
cents = cents -qtr * 25
This calculates the nickel in remaining cents
nkl = int(cents/5)
This calculates the pennies in remaining cents
pny = cents -nkl * 5
This prints the required output
print(qtr,"quarters,",nkl,"nickels,",pny,"pennies")
Give examples of applications that access files by each of the following methods:
+ Sequentially.
+ Random.
Answer:
Explanation:
Usually, applications would have the capability of using either one of these options. But for the sake of the question here are some that usually prefer one method over the other.
Any program that targets an API usually uses Sequential access. This is because API's contain all of the data as objects. Therefore, you need to access that object and sequentially navigate that object to the desired information in order to access the data required.
A music application would have access to an entire folder of music. If the user chooses to set the application to randomly play music from that folder, then the application will use a Random Access method to randomly choose the music file to load every time that a song finishes.

Over-activity on LinkedIn?
Answer:
Being over-enthusiastic and crossing the line always get you in trouble even if you’re using the best LinkedIn automation tool in the world.
When you try to hit the jackpot over the night and send thousands of connection requests in 24 hours, LinkedIn will know you’re using bots or tools and they will block you, temporarily or permanently.
This is clearly against the rules of LinkedIn. It cracks down against all spammers because spamming is a big ‘NO’ on LinkedIn.
What people do is that they send thousands of connection requests and that too with the same old spammy templates, “I see we have many common connections, I’d like to add you to my network.”
It will only create spam.
The LinkedIn algorithm is very advanced and it can easily detect that you’re using a bot or LinkedIn automation tool and you’ll be called out on it.

ITS A SIMPLE ANSWER BUT THE PROBLEM IS TOO BIG!
Explanation:
The phishing email might contain a link which on clicking will take you to a fake web page. For example, the link might take you to a fake bank website which looks very legitimate but in reality is just a lookalike. If the victim falls for the scam and enters his/her account details on the website, the details will actually go to the hacker's server instead of going to the bank and the hacker will have all the information that the victim has provided on the website.
