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.
2. Create a program that allows a user to input customer records (ID number, first name, last name,
and balance owed) and save each record to a file.
3. Write an application for Limpopo's Car Care Shop that shows a user a list of available services: oil
change, tire rotation, battery check, or brake inspection. Allow the user to enter a string that

Your program should store the correct answers shown above in an array. It should ask the user to
enter the student's answers for each of the 20 questions, and the answers should be stored in another
array. After the student's answers have been entered, the program should display a message
indicating whether the student passed or failed the exam. (A student must correctly answer 15 of
the 20 questions to pass the exam.) It should then display the total number of correctly answered
questions, the total number of incorrectly answered questions, and a list showing the question
numbers of the incorrectly answered questions.
Input Validation: Only accept the letters A, B, C, or…

- 99 question Reza Enterprises sells tickets for buses, tours, and other travel services. Because Reza frequently mistypes long ticket numbers, Reza Enterprises has asked his students to write an application that shows if a ticket is invalid. Your application/program tells the ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you lose the last digit of the number, then divide by 7, the remainder of the division is exactly the same to the last dropped digit. This process is shown below: Step 1: Enter the ticket number; for example 123454 Step 2: Remove the last digit, leaving 12345 Step 3: Determine the remainder when the ticket number from step 2 is divided by 7. In this case, 12345 divided by 7 leaves a remainder of 4. Step 4: Display a message to the ticket agent indicating whether the ticket number is valid or not. If the ticket number is valid, save the number to a .txt file called “tickets.txt” and.arrow_forwardReza Enterprises sells tickets for buses, tours, and other travel services.

The formula, which is known as the future value formula, is:F=P×(1+i)tThe terms in the formula are as follows:o F is the future value of the account after the specified time period.o P is the present value of the account.o i is the monthly interest rate.o t is the number of months.Write a program that prompts the user to enter the account’s present value, monthlyinterest rate, and the number of months that the money will be left in the account. Theprogram should pass these values to a function named futureValue that returns thefuture value of the account, after the specified number of months. The program shoulddisplay the account’s future value. i attached the screenshot of the output so the output should look like that. the coding should be in c++arrow_forward

[Hint:arrow_forwardThis is the question: Write an application that displays every perfect number from 1 through 1,000. A perfect number is one that equals the sum of all the numbers that divide evenly into it. For example, 6 is perfect because 1, 2, and 3 divide evenly into it, and their sum is 6; however, 12 is not a perfect number because 1, 2, 3, 4, and 6 divide evenly into it, and their sum is greater than 12.
