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.

Answer and Explanation:
In C programming language:
char fun(int*a, int*b){
printf("enter two integers: ");
scanf("%d%d",a,b);
int e;
printf("please enter a character: ");
e=getchar();
return e;
}
int main(int argc, char *argv[]) {
int d;
int f;
int g;
fun();
printf("%d%d%d", d, f, g);
}
We have declared a function fun type char above and called it in main. Note how he use the getchar function in c which reads the next available character(after the user inputs with printf()) and returns it as an integer. We then return the variable e holding the integer value as char fun() return value.

Select the pseudo-code that corresponds to the following assembly code. Assume that the variables a, b, c, and d are initialized elsewhere in the program. You may want to review the usage of EAX, AH, and AL (IA32 registers). Also recall that the inequality a > b is equivalent to b < a. i.e. If A is greater than B, that's equivalent to saying that B is less than A.

What is the pseudo-codeIn assembly code, the command cmp AH, c checks if the high byte of the EAX register (AH) has the same value as the variable c. Then, if the value in AH is more than the value in c, the instruction jg option1 will move to option1.

Write a game that performs the roll of two dice randomly. The game should first ask for a target sum. Everytime the player enters r, the program should repeatedly print the side of the dice on a separate line. The game should stop prompting if one of these two events occur: -The sum of the two sides is equal to the target sum. -The player enters q.
Answers
Answer:
Explanation:
The following program was written in Java. It asks the user to first enter the target sum. Then it creates a while loop that continues asking the user to either roll dice or quit. If they decide to roll, it rolls the dice and prints out both values. If the target sum was hit, it prints that out and exits the program otherwise it loops again. The code has been tested and can be seen in the attached image below.
import java.util.Random;
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
Random rand = new Random();
Scanner in = new Scanner(System.in);
System.out.print("Enter Target Sum: ");
int targetSum = in.nextInt();
while (true) {
System.out.println("r: Roll Again");
System.out.println("q: Quit");
String choice = in.next();
char choiceModified = choice.toLowerCase().charAt(0);
if (choiceModified == 'r') {
int roll1 = rand.nextInt(6) + 1;
int roll2 = rand.nextInt(6) + 1;
int total = roll1 + roll2;
System.out.println("Dice 1: " + roll1);
System.out.println("Dice 2: " + roll2);
if (total == targetSum) {
System.out.println("Target Sum of " + targetSum + " hit.");
break;

} else if (choiceModified =='q') {

If your organization hires a new employee, what would you do to create a user account in the Linux system and add the account to a group? What commands would you use? What configuration files would you check and modify?
Answers
Following are the responses to this question:
The user account is "olivia".In the Linux system to see the account go to the "/home directory".For the configuration file we use ".bash_logout , .bash_profile, and .bashrc" files.Creating users:
We will use the useradd command to achieve this. Using that same command, you can create users who would log in or customers who would log in (in the case of creating a user for a software installation).
In its basic form, the command is as follows:
[Options] useradd usernameTake this user olivia, for instance. Assuming that you had been to issue the command prompt:
olivia has become a user.Users are added to the system without the need for a home directory and are unable to log on. It if we were using this rather than running the command without arguments?
sudo using useradd -m oliviaUsing the command above, a new user would be created, including a home directory that corresponded to the username. That means that you might now see the name "olivia" in the directory "/home".
But what about the lockout concern that was raised earlier? Both these methods are possible. After creating the user, you can enter the following command:
Password for olivia is: sudo passwd oliviaYou'll be requested to enter & verify your new password once you've completed the process. This unlocks the user profile, allowing them to log in.
This command might look like if you wanted to accomplish it in one go:
sudo useradd -m olivia -p PASSWORDYou should be using Passcodes as the login for the user olivia.
As soon as the user logs in, he or she can update their account password by using the password command to input their current password, and afterward entering/verifying their new one.
To create a user that has no personal account and cannot log in, execute the following instructions:
sudo use useradd as the-M USERNAME sudo use usermod as the -L USERNAMEThe user to be added is identified by USERNAME.
It establishes a user with really no root folder and prevents them from signing in with a second operation.
To add an existing user to a group on Linux, follow the instructions:
As root, log in to your accountUse the useradd instruction to add a new user (for example, useradd roman)If you'd like to log on as a new customer, type su plus that user's name.Entering the word "exit" will logout you from your account.Another way to add a user to a group under Linux would be to use the following syntax:
Alternatively, you can use the usermod command.The name of the club should be substituted for example group in this sentence.Example username should be replaced with the name of the user you'd like added.The following operations are performed when a new login is added to the system.
The user's home directory (/home/username by default) is now created.To set configuration files for the user's session, the following secret files are copied into another user's home directory..bash_logout
.bash_profile
.bashrc
/var/spool/mail/username includes the user's mail spool.The new user account is arranged in groups with the same name.Learn more:

Explanation:
Required
An algorithm to solve (a), (b) and (c)
For Series (a):
This series is a geometric progression and the common ratio is x
i.e.
[tex]r = x/1 = x^2/x = ...... = x^{n+1}/x^n =x[/tex]
So, the sum of the series is:
Sum = Previous Sums + x^i --- where i is between 0 and 20 (inclusive)
For Series (b):
This series is a geometric progression and the common ratio is -x
i.e.
[tex]r = -x/1 = -x^2/x = ...... = -(x^{n+1}/x^n) = -x[/tex]
So, the sum of the series is:
Sum = Previous Sums + (-x^i) --- where i is between 0 and 20 (inclusive)
For Series (c):
This series is a neither arithmetic nor geometric progression.
It obeys the following rule:
[tex]\frac{x^i}{1+i}[/tex] --- where i is between 0 and 20 (inclusive)
So, the sum of the series is:
Sum = Previous Sums + [tex]\frac{x^i}{1+i}[/tex]
