Create an application containing an array that stores eight integers. Prompt the user to enter the 8 integers. The application should call five methods that in turn (1) display all the integers, (2) display all the integers in reverse order, (3) display the sum of the integers, (4) display all values less than the calculated average value, and (5) display all values that are higher than the calculated average value. Save the file as ArrayMethodDemo
Write an application containing three parallel arrays that hold 10 elements each. The first array hold four-digit student ID numbers, the second array holds first names, and the third array holds the students’ grade point averages. Use dialog boxes to accept a student ID number and display the student’s first name and grade point average. If a match is not found, display an error message that includes the invalid ID number and allow the user to search for a new ID number.

- Create an application that contains an enumeration (enum) that represents the days of the week. Display a list of the days, then prompt the user for a day. Display business hours for the chosen day. Create your own business hours stored in an array; however, every day of the week should have different hours. Although companies do not normally have different business hours every day of the week, programming your code with this difference will help in finding and fixing coding errors. java programarrow_forwardJAVA Write an application containing three parallel arrays that hold 10 elements each.

- JAVA I cannot figure this one out no matter what I do I cannot get it to run. Please write it in a student way not in an too advance way. Write an application containing three parallel arrays that hold 10 elements each. The first array hold four-digit student ID numbers, the second array holds first names, and the third array holds the students’ grade point averages. Use dialog boxes to accept a student ID number and display the student’s first name and grade point average. If a match is not found, display an error message that includes the invalid ID number and allow the user to search for a new ID number.arrow_forwardCreating Enumerations In this section, you create two enumerations that hold colors and car model types. You will use them as field types in a Car class and write a demonstration program that shows how the enumerations are used. 1. Open a new file in your text editor, and type the following Color enumeration: enum Color {BLACK, BLUE, GREEN, RED, WHITE, YELLOW}; 2. Save the file as Color.java. 3. Open a new file in your text editor, and create the following Model enumeration: enum Model {SEDAN, CONVERTIBLE, MINIVAN}; 4. Save the file as Model.java. Next, open a new file in your text editor, and start to define a Car class that holds three fields: a year, a model, and a color. public class Car { private int year; private Model model; private Color color; 5. Add a constructor for the Car class that accepts parameters that hold the values for year, model, and color as follows: public Car(int yr, Model m, Color c) { year = yr; model = m; color = c; } 6. Add a display()…arrow_forwardCreate a program that will track student names and their grades and perform some simple statistics. In a main class create an ArrayList or array that will hold Student names. Create a second (parallel) ArrayList or array that will hold student scores, represented as integers from 0-100. Prompt the user to enter some students (for your purposes, enter information for at least three). Then present a menu for the user. The menu will contain the following options: Find student with the highest grade (print out the name of the student) Find grade average (return the grade average back to the calling method) print information of all students exit program Create methods in your main class for these options. Keep the your ArrayList or array inside your main method and pass it to the other methods; it should not be a global variable. Validate the grade; the user should not enter anything below 0 or above 100.arrow_forward
