1. Write an application that throws and catches an ArithmeticException when you attempt to take the square root of a negative value. Prompt the user for an input value and try the Math.sqrt() method on it. The application either displays the square root or catches the thrown Exception and displays an appropriate message. Save the file as SqrtException.java.
2. Create a ProductException class whose constructor receives a String that
consists of a product number and price. Save the file as ProductException.java.
Create a Product class with two fields, productNum and price. The Product
constructor requires values for both fields. Upon construction, throw a
ProductException if the product number does not consist of three digits, if the
price is less than $0.01, or if the price is over $1,000. Save the class as Product.java.
Write an application that establishes at least four Product objects with valid and invalid values. Display an appropriate message when a Product object is created
successfully and when one is not. Save the file as ThrowProductException.java.

Hi, I provided some explanation of key terms.

Explanation:

Wireless hacking: basically the term refers to any unethical activity carried over a radio wave-connected network (eg Internet or Wifi connection) that would provide unauthorized access to information.

Hardware hacking: On the other hand, hardware hacking involves resetting physical hardware with the objective of using it in a way not originally intended by the manufacturer.

Answer:

The not strong security methods are:

a. Disabling SSID

b. WPS

Explanation:

When you disable SSID, you only make your Wi-Fi secure for the less determined attackers.  By disabling the SSID (network name), those who are less technically inclined are prevented from connecting to the network but, this will not deter a more determined and technically savvy adversary.  The best two options are MAC filtering and setting encryption.  WPS (Wi-Fi Protected Setup) enables the process of connecting to a secure wireless network from a computer or other device easier instead of making it harder.

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)

Why is cloud better than on-premise? Dubbed better than on-premise due to its flexibility, reliability and security, cloud removes the hassle of maintaining and updating systems, allowing you to invest your time, money and resources into fulfilling your core business strategies.

The security of the cloud vs. on-premises is a key consideration in this debate. Cloud security controls have historically been considered less robust than onprem ones, but cloud computing is no longer a new technology. . A company running its own on-premises servers retains more complete control over security.

Answer:

d. All of the above

Explanation:

A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer how to perform a specific task and to solve a particular problem.

A software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications.

In Computer science, management of software development consist of;

a. Process: it involves the stages through which a software application is analyzed, designed, developed, tested, etc.

b. People: it refers to the individuals involved in the software development process.

c. Project: it's the entirety of the stages a software goes through before it gets to the end user.

Answer:

The updated program in C is as follows:

#include <stdio.h>

union myUnion{ char c; short s; int i; long l; };

int main(){

   union myUnion inputs;

   printf("Character: ");    scanf("%c", &inputs.c);

   printf("Output: %c", inputs.c);

   printf("\nShort: ");    scanf("%hd", &inputs.s);

   printf("Short: %hd", inputs.s);

   printf("\nInteger: ");    scanf("%d", &inputs.i);

   printf("Output: %d", inputs.i);

   printf("\nLong: ");    scanf("%ld", &inputs.l);

   printf("Long: %ld", inputs.l);

   return 0;

   }

The pseudocode is as follows:

Function union myUnion {

character; short; int; long

}

main() {

myUnion inputs;

Input inputs.c;  Print inputs.c

Input inputs.s; Print inputs.s

Input inputs.i; Print inputs.i;

Input inputs.l; Print inputs.l

}

Explanation:

This defines the union function

union myUnion{ char c; short s; int i; long l; };

The main begins here

int main(){

This calls the union function to main

   union myUnion inputs;

This prompts and gets input for character variable

   printf("Character: ");    scanf("%c", &inputs.c);

This prints the character input

   printf("Output: %c", inputs.c);

This prompts and gets input for short variable

   printf("\nShort: ");    scanf("%hd", &inputs.s);

This prints the short input

   printf("Short: %hd", inputs.s);

This prompts and gets input for integer variable

   printf("\nInteger: ");    scanf("%d", &inputs.i);

This prints the integer input

   printf("Output: %d", inputs.i);

This prompts and gets input for long variable

   printf("\nLong: ");    scanf("%ld", &inputs.l);

This prints the long input

   printf("Long: %ld", inputs.l);

   return 0;

   }

if userInput % 400 == 0

  Put userInput to output

  Put " is a leap year" to output

else

  if userInput % 4 == 0

     Put userInput to output

     Put " is a leap year" to output

  else

     Put " is not a leap year" to output

Explanation:

I don't know what is so special about Coral but here we go. I couldn't find and IDE that supported Coral so I just used their Coral simulator on their website. The first if statement on line 5 determines if the number is divisible by 400. If so, the leap year is on a century year e.g 1900 1800. If not, the else statement will be executed and the second if statement will execute. If the number is divisible by 4, it is a leap year. If not, the else statement gets executed in which case the number was not a century leap year or a leap year. After that the program terminates.

Hope this helped :)  If it didn't let me know and I do my best to find out what went wrong.

Answer:

universal design

Explanation:

Using simplified language and numbers, using large font type with more spacing between questions, and having students record answers directly on their tests are all examples of universal design.

Universal Design can be regarded as design that allows the a system, set up , program or lab and others to be

accessible by many users, this design allows broad range of abilities, reading levels as well as learning styles and ages and others to have access to particular set up or program.

it gives encouragment to the development of ICTS which can be

usable as well as accessible to the widest range of people.

Answer:

Code:

CREATE TABLE student (

stu_code INTEGER PRIMARY KEY,

prof_code INTEGER

);

INSERT INTO student VALUES (100278,null);

INSERT INTO student VALUES (128569,2);

INSERT INTO student VALUES (512272,4);

INSERT INTO student VALUES (531235,2);

INSERT INTO student VALUES (531268,null);

INSERT INTO student VALUES (553427,1);

CREATE TABLE professor (

prof_code INTEGER PRIMARY KEY,

dept_code INTEGER

);

INSERT INTO professor VALUES (1,2);

INSERT INTO professor VALUES (2,6);

INSERT INTO professor VALUES (3,6);

INSERT INTO professor VALUES (4,4);

The SQL NATURAL JOIN is a type of EQUI JOIN and is structured in such a way that, columns with the same name of associated tables will appear once only. In our Example, Prof_code will appear only once and it will be matched in both the table;  

SELECT * FROM Student natural join Professor on student.prof_code=Professor.prof_code ;  

Stud_code   Prof_code  Dept_code

128569        2           6

512272        4           4

531235        2           6

553427        1           2

EQUI JOIN performs a JOIN against equality or matching column(s) values of the associated tables and an equal sign (=) is used as a comparison operator in the where clause to refer to equality. In our example, it will only show the result with prof_code=2 from the natural join result.

SELECT * FROM Student join Professor on student.prof_code=Professor.prof_code where student.prof_code=2;

Stud_code Prof_code Prof_code Dept_code

128569     2         2         6

531235     2         2         6

In SQL the FULL OUTER JOIN combines the results of both left and right outer joins and returns all (matched or unmatched) rows from the tables on both sides of the join clause.

SELECT * FROM professor full outer join student on professor.prof_code=student.prof_code ;

Stud_code Prof_code Prof_code Dept_code

100278                

128569    2          2         6

512272    4          4         4

531235    2          2         6

531268    

                    3         6

553427    1          1         2

Answer:

1.8 * 10^11 m

Explanation:

Given that :

Time taken for tweet to me posted after been sent, t = 10 minutes

t in seconds :

60 seconds = 1 minute

10 minutes = (10 * 60) = 600 seconds

Tweet sent will br transmitted at the speed of light, c = 3 * 10^8 m/s

Recall :

Speed = distance / time

Distance = speed * time

Distance of Curiosity from Earth = (3 * 10^8 * 600)

Distance of curiosity from earth = 1.8 * 10^11 m

Solution :

'AND" operation is a logical operation and is used in logical connective combining two statements and in truth tables.

Using AND operation verifies whether the outcome P and Q is true only when both the P as well as Q are true.  If one of the P or Q is not true, then outcome result will be false.

The open() operation notifies the system that the named file is about to become active. The close() operation notifies the system that the named file is no longer in active use by the user who issued the close operation.

Answer:

The algorithm is as follows:

1. Start

2. Capacity = 100%

3. Input Status (True/False)

4. While Status == True

    4.1. Read Quantity (%)

    4.2. Capacity = Capacity - Quantity

    4.3. If Capacity < 40%

          4.3.1 Display Yellow Flash

    4.4. Input Status (True/False)

5. Stop

Explanation:

This starts the algorithm

1. Start

The capacity of the machine is initialized to 100%

2. Capacity = 100%

This gets the status of the sales

3. Input Status (True/False)

The following iteration is repeated until the status is false

4. While Status == True

Read current sales quantity from the user

    4.1. Read Quantity (%)

Remove the quantity from the capacity

    4.2. Capacity = Capacity - Quantity

Check is capacity is below 40%

    4.3. If Capacity < 40%

If yes, display yellow flashes

          4.3.1 Display Yellow Flash

This gets the status of the sales

    4.4. Input Status (True/False)

End algorithm

5. Stop
