Write an application that displays a series of at least
five student ID numbers (that you have stored in an
array) and asks the user to enter a numeric test score
for the student. Create a ScoreException class, and
throw a ScoreException for the class if the user does
not enter a valid score (less than or equal to 100).
Catch the ScoreException and then display an
appropriate message. In addition, store a 0 for the
student's score. At the end of the application, display all
the student IDs and scores. Save the files as
ScoreException.java and TestScore.java.
this practice assignement wants me to Write an application that contains an array of 10 multiple-choice quiz questions related to your favorite hobby. Each question contains three answer choices. Also create an array that holds the correct answer to each question—A, B, or C. Display each question and verify that the user enters only A, B, or C as the answer—if not, keep prompting the user until a valid response is entered. If the user responds to a question correctly, display Correct!; otherwise, display The correct answer is and the letter of the correct answer. After the user answers all the questions, display the number of correct and incorrect answers

Your program should store these correct answers in an array. The program should read the student’s answers for each of the 20 questions from a text file and store the answers in another array. (Create your own text file to test the application.) After the student’s answers have been read from the file, 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.

- Allow a user to enter any number of double values up to 15. The user should enter 99999 to quit entering numbers. Display an error message if the user quits without entering any numbers; otherwise, display each entered value and its distance from the average. Save the file as DistanceFromAverage.java. Now, modify that program to first prompt the user to enter an integer that represents the array size. Java generates a NumberFormatException if you attempt to enter a noninteger value using nextInt(); handle this exception by displaying an appropriate error message. Create an array using the integer entered as the size. Java generates a NegativeArraySizeException if you attempt to create an array with a negative size; handle this exception by setting the array size to a default value of five. If the array is created successfully, use exception-handling techniques to ensure that each entered array value is a double before the program calculates each element’s distance from the average.…arrow_forwardMake an application that displays a series of at least five student ID numbers (that you have stored in an array) and asks the user to enter a numeric test score for the student.

The program contains an array that holds the 10 zip codes of areas to which the company makes deliveries. (Note that this array is created for you and does not need to be changed.) Prompt a user to enter a zip code, and display a message indicating whether the zip code is in the company’s delivery area. For example if the user enters a zip code in the array, such as 60007, the output should be Delivery to 60007 ok. If the user enters a zip code not in the array, such as 60008, the output should be Sorry - no delivery to 60008.arrow_forwardYou are a manager of a Wally's Training Gym and you encourage your trainers to enroll new members.

Write an application that allows the user to enter 15 Trainer's names and the number of new members they have enrolled into an array. Output is to display the number of trainers who are in each category. Use good programming techniques that you have learned throughout the course. Use appropriate variable names, use an array to store the names and number of new enrollees, and use prompts for the input and labels with the display.

- Write a C# console application named MaxMin that asks the user to enter 5 integers, representing the test scores of 5 students. For each input score, you need to check and make sure it is valid (i.e., in between 0 and 100). Store the 5 integers in an int array, and then find and display the highest and the lowest scores on the screen. For example, if you have the 5 scores as {85, 72, 65, 98, 80}, then the output message should be "The highest score is 98, and the lowest score is 65". Hint: use a while loop.arrow_forwardCreate a Console application that does the following:This program accepts 10 random names. It must use a single array to store the names; there will be onearray to store all 10 names.1.
