You are tasked with creating a Java program that simulates a simple quiz game. The program should prompt the user with a series of questions and allow them to enter their answers. After the user has answered all the questions, the program should compute and display the final score based on the number of correct answers.For this assignment, write a Java program that implements the functionality described in the scenario. Ensure that your program is error-free, compiles successfully, and produces the expected output. Test your program with different inputs to verify its correctness.Make sure the following requirements are met:The program should include five multiple-choice questions with four options.The four options should be labeled A, B, C, and D.The program should prompt the user to enter their answer by typing the corresponding letter (A, B, C, or D).After the user has entered their answer for each question, the program should compare it to the correct answer and keep track of the number of correct responses.The program should compute and display the final score as a percentage of the total number of questions.Use if and switch case statements to handle user input and compare it to the correct answers.Include comments to explain the purpose of each section of code and enhance code readability.

For this project you will write a Java program that will run a simple math quiz. Your program will generate two random integers between 1 and 20 and then ask a series of math questions. Each question will be evaluated as to whether it is the right or wrong answer. In the end a final score should be reported for the user. (See below for how to generate random numbers).Sample Ouptut This is a sample transcript of what your program should do. Values in the transcript in BOLD show the user inputs. So in this transcript the user inputs 33, Jeremy, 24, -16, and 80 the rest is output from the program.Enter a random number seed: 33Enter your name: JeremyHello Jeremy!Please answer the following questions:4 + 20 = 24Correct!4 - 20 = -16Correct!4 * 20 = 80Correct!You got 3 correct answers!That's 100.0%!Your code will behave differently based on the random number seed you use and the answers provided by the user. Here is a second possible execution of this code. As before, values in BOLD are provided by the user - in this case 54, Bob, 8, 8, and 8 - the rest is the output of the program when you run it.Enter a random number seed: 54Enter your name: BobHello Bob!Please answer the following questions:20 + 12 = 8Wrong!The correct answer is: 3220 - 12 = 8Correct!20 * 12 = 8Wrong!The correct answer is: 240You got 1 correct answers!That's 33.33333333333333%!Random numbers: Random numbers in a computer are rarely random. Instead computers use something known as a pseudorandom number generator. This is a process that gives the appearance of generating a random number sequence, but in fact is entirely predictable if you know the value used to seed (i.e. start) the process. The upshot of this is that we can get predictable behavior out of a random number generator for testing by using a known seed that we use as input as here in this program. Then when we move it to actual use, we can use a different seed to give more random behavior - typically by using the system clock or other input that will be different from one execution to the next as our seed value instead of prompting for it.To code this, we don't want to write our own pseudorandom generator. Not only would that be a fairly complicated thing to do with the Java knowledge we have currently, there are already psuedorandom generators built into the Java library for our use. For this project you will need to use the generator implemented in the Java Random class. You will need to create a new Random object and then draw numbers from it using the nextInt method of the Random class.The Random object's instance method nextInt will provide a random number between 0 and an upper bound (not including the upper bound) for example, the code below will provide an integer value for the variable x between 0 and 9 and a value for y between 1 and 10:int seed = 1024; // For your project, use a value entered by the user as your seed.Random rnd = new Random(seed);int x = rnd.nextInt(10); // x will be an integer between 0 and 9int y = rnd.nextInt(10) + 1; // y will be an integer between 1 and 10How would you modify the code above so that Random uses the seed provided by the user and x will be assigned a value between 1 and 20? That's what you'll need to do for this project.Note that you only ever want to create a single Random object in your code, even if you are generating multiple random numbers!  Just make multiple calls to nextInt to get different random numbers, as the code snippet above does.Displaying percentages: To display the percentage of answers correct you need to convert your integer count of the number of correct answers to a double percentage value. The following piece of Java code will display the decimal value of the fraction 1/4. Think about how you would modify this code to get the percentage of correct answers as required by this assignment:int numerator = 1;double denominator = 4.0;double quotient = numerator/denominator;System.out.println(quotient); // will display a value of 0.25

Enter the number of questions to answer. Ensure that the input is a positive integer. Continueprompting users with “The number of questions cannot be zero or negative. Re-enter: ” and acceptinput from users until a positive integer is provided.2. Utilize the code from Task A to generate questions involving addition (+), subtraction (-), multipli-cation (*), division (/), and remainder (%), with operands restricted to single-digit integers.3. Calculate and print the correctness percentage.4. If the percentage is 90 or higher, print ’A’; if it’s 80 or higher, print ’B’; if it’s 70 or higher, print ’C’;if it’s 60 or higher, print ’D’; otherwise, print ’F’.

Write a Java program that determines a student’s grade. The program will read three types ofscores(quiz, mid-term, and final scores) and determine the grade based on the following rules: -if theaverage score >=90% =>grade=A -if the average score >= 70% and <90% => grade=B -if theaverage score>=50% and <70% =>grade=C -if the average score<50% =>grade=F

Code 1 Copy this code, compile and run it so you can answer the questions. import java.util.Scanner; public class UserGradingSystem { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); // Prompt user to enter scores for three subjects System.out.print("Enter math score: "); int mathScore = scanner.nextInt(); System.out.print("Enter science score: "); int scienceScore = scanner.nextInt(); System.out.print("Enter English score: "); int englishScore = scanner.nextInt(); // Calculate the average score int averageScore = (mathScore + scienceScore + englishScore) / 3; // Determine the overall grade if (averageScore >= 90) { System.out.println("Outstanding!"); } else if (averageScore >= 80) { System.out.println("Very Good!"); } else if (averageScore >= 70) { System.out.println("Good"); } else { System.out.println("Needs improvement"); } } } What if the user enters "85," "90," and "88," but mistakenly adds a semicolon after the English score, entering "88;"? (Refer to Code 1) Group of answer choices The program outputs "Needs improvement" for the invalid score. The program handles it gracefully, treating the input as valid. The program outputs "Outstanding!" for the valid scores. The program crashes with a runtime exception.

Write a Java program that reads an unspecified number of scores anddetermines how many scores are above or equal to the average, and how many scoresare below the average. Enter a negative number to signify the end of the input. Assumethe maximum number of scores is 100.
