Write an application that displays a series of at leastfive student ID numbers (that you have stored in anarray) and asks the user to enter a numeric test scorefor the student. Create a ScoreException class, andthrow a ScoreException for the class if the user doesnot enter a valid score (less than or equal to 100).Catch the ScoreException and then display anappropriate message. In addition, store a 0 for thestudent's score. At the end of the application, display allthe student IDs and scores. Save the files asScoreException.java and TestScore.java.

JavaDriver Program Write a driver program that contains a main method and two other methods. Create an Array of Objects In the main method, create an array of Food that holds at least two foods and at least two vegetables. You can decide what data to use. Method: Print Write a method that prints the text representation of the foods in the array in reverse order (meaning from the end of the array to the beginning). Invoke this method from main. Method: Highest Sugar Food Write a method that takes an array of Food objects and finds the Food that has the most sugar. Note that the method is finding the Food, not the grams of sugar. Hint: in looping to find the food, keep track of both the current highest index and value. Invoke this method from main.
Q1: The local Driver's License Office has asked you to write a program that grades the writ- ten portion of the driver's license exam. The exam has 20 multiple choice questions. Here are the correct answers: 1. A 2. D 3. B 4. B 5. C 6. B 7. A 8. B 9. C 10. D 11. A 12. C 13. D 14. B 15. D 16. C 17. C 18. A 19. D 20. B 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…
Write a program that generates a random number in the range of 1 through 100, and asks the user to guess what the number is. If the user’s guess is higher than the random number, the program should display “Too high, try again.” If the user’s guess is lower than the random number, the program should display “Too low, try again.” If the user guesses the number, the application should congratulate the user and then generate a new random number so the game can start over.Optional Enhancement: Enhance the game so it keeps count of the number of guesses that the user makes. When the user correctly guesses the random number, the program should display the number of guesses.
Using C# create a console app doing the following Write a method that takes two integers and displays their sum. Write a method that takes five doubles and returns their average. Write a method that returns the sum of two randomly generated integers. Write a method that takes three integers and returns true if their sum is divisible by 3, false otherwise. Write a method that takes two strings and displays the string that has fewer characters. Write a method that takes an array of doubles and returns the largest value in the array. Write a method that generates and returns an array of fifty integer values. Write a method that takes two bool variables and returns true if they have the same value, false otherwise. Write a method that takes an int and a double and returns their product. Write a method that takes a two-dimensional array of integers and returns the average of the entries.
Assume that the population of Mexico is 128 million and that the population increases 1.01 percent annually. Assume that the population of the United States is 323 million and that the population is reduced 0.15 percent annually. Write an application that displays the populations for the two countries every year until the population of Mexico exceeds that of the United States, and display the number of years it took. Save the file as Population.java.
Design an application that declares an array of 10 StockTransactionobjects. Prompt the user for data for each object, and then display all the values. Design an application that declares an array of 10 StockTransactionobjects. Prompt the user for data for each object, and then pass the array to a method that determines and displays the two stocks with the highest and lowest price per share.
Design and implement an application that plays the Hi-Lo guessing game with numbers. The program should pick a random number between 1 and 100 (inclusive) and then repeatedly prompt the user to guess the number. On each guess, report to the user that he or she is correct or that the guess is high or low. Continue accepting guesses until the user guesses correctly or chooses to quit. Use a sentinel value to determine whether the user wants to quit. Count the number of guesses, and report that value when the user guesses correctly. At the end of each game (by quitting or a correct guess), prompt to determine whether the user wants to play again. Continue playing games until the user chooses to stop.
TOPICS: Using Classes and Objects MUST BE IN JAVA. PLEASE USE COMMENTS AND WRITE THE CODE IN SIMPLEST FORM. 1. Write an application that prompts for and reads the user’s first and last name (separately), then displays a string composed of the first four characters of the user’s last name, followed by the first two letters of the user’s first name, followed by a random number in the range of 10 to 99. Assume that the last name is at least four letters long. Similar algorithms are sometimes used to generate usernames for new computer accounts. Testing: If the inputs were “Michael” and “Jackson,” the output should look like “JackMi42.” Include several tests with different inputs, including your own name.
Write a java application that handles a student report card. The application shall save the marks of computer science, math and English. Each subject has a total of 50 marks. If a student obtains at least 75/150 marks, an event will trigger and show a congratulation message on passing the exam. Otherwise, it will display an “F” grade.
Write an application in which the user can enter a date using digits and slashes (for example, "6/24/2012"), and receive output that displays the date with the month shown as a word (such as “June 24, 2012"). Allow for the fact that the user might or might not precede a month or day number with a zero (for example, the user might type "06/24/2012" or “6/24/2012"). Do not allow the user to enter an invalid date, defined as one for which the month is less than 1 or more than 12, or one for which the day number is less than 1 or greater than the number of days in the specified month. Also display the date's ordinal position in the year; for example, 6/24 is the 176th day. In this application, use your knowledge of arrays to store the month names, as well as values for the number of days in each month so that you can calculate the number of days that have passed. Figure shows the output when the user has entered 6/24/2012. Save the application as Date.java Input Enter a date in the format…
Create a program named Auction that allows a user to enter an amount bid on an online auction item. Include three overloaded methods that accept an int, double, or string bid. Each method should display the bid and indicate whether it is over the minimum acceptable bid of $10. If the bid is greater than or equal to $10, display Bid accepted. If the bid is less than $10, display Bid not high enough. If the bid is a string, accept it only if one of the following is true: It is numeric and preceded with a dollar sign. It is numeric and followed by the word dollars. Otherwise, display a message that says Bid was not in correct format. using static System.Console; public class Auction { static void Main() { // Write your main here } public static void AcceptBid(int bid, int min) { } public static void AcceptBid(double bid, int min) { } public static void AcceptBid(string bid, int min) { } }
