- Create an application via NetBeans with named Pizza that storesinformation about a single pizza. It should contain the following:• Private instance variables to store the size of the pizza (eithersmall, medium, or large), the number of cheese toppings, the number ofbeef toppings, and the number of chicken toppings.• Constructor(s) that set all of the instance variables.• Public methods to get and set the instance variables.• A public method named calcCost( ) that returns a double that is thecost of the pizza.Pizza cost is determined by: Small: OR10 + OR 2 per topping Medium: OR 12 + OR 2 per topping Large: OR 14 + OR 2 per topping• A public method named getDescription( ) that returns a Stringcontaining the pizza size, quantity of each topping, and the pizzacost as calculated by calcCost( ).Create an application named ConvertMilesToKilometers whose Main( ) method prompts a user for a number of miles, passes the value to a method that converts the value to kilometers, and then returns the value to the Main() method where it is displayed. A mile is 1.60934 kilometers.Modify the NumbersDemo application whose main() method holds two integer variables. Assign values to the variables. In turn, pass each value to methods named displayTwiceTheNumber(), displayNumberPlusFive(), and displayNumberSquared(). public class NumbersDemo { public static void main (String args[]) { // Write your code here } public static void displayTwiceTheNumber(int n) { // Write your code here } public static void displayNumberPlusFive(int n) { // Write your code here } public static void displayNumberSquared(int n) { // Write your code here } }
- Create an application for a library and name it FineForOverdueBooks. TheMain() method asks the user to input the number of books checked out and the number of days they are overdue. Pass those values to a method named DisplayFine that displays the library fine, which is 10 cents per book per day for the first seven days a book is overdue, then 20 cents per book per day for each additional day.FOR JAVA, PLEASE URGENT Part I Use Company class and create OptionDialog for 5 any methods about company. Part II Modify the methods to get input from user by dialog systems (InputDialog, OptionDialog etc.). You can add more if you don’t have proper methods to utilize dialogues. Part III Modify the exception handling codes to show the caught error by MessageDialog. Part IV Create an UI by JFrame in order to initialize the Company objects.Write a method with the following specifications:name: DisplayMenuarguments: nonereturn value: nonetasks: display the following menu choice on the screenCalculation Menu3) Calculate Sum 4) Calculate Sum of Squares5) Calculate Sum of Cubes0) To ExitEnter the number that corresponds to your choice: You may beautify the output to your own likings. You don’t have to implement the functionalities of the various menu choices at this stageCall this method from your main. Modify your main so that the above method is call repeatedly. The program will terminate when the user enters 0. Any other choice should produce an error message. Because you will not be doing any arithmetic you may accept the user response either as an int, or a char or a string. Write a method with the following specifications:name : CalculateSumarguments : a single int representing the number of inputs that will constitute the sumreturn value : int representing the sum of all the user inputsdisplays…
- Create a program named FindSquareRoot that finds the square root of a user’s input value. The Math class contains a static method named Sqrt() that accepts a double and returns the parameter’s square root. If the user’s entry cannot be converted to a double, display an appropriate message, and set the square root value to 0. Otherwise, test the input number’s value. If it is negative, throw a new ApplicationException to which you pass the message “Number can’t be negative.” and again set sqrt to 0. If the input value is a double and not negative, pass it to the Math.Sqrt() method, and display the returned valueIn Java Given the following CircleDriver.java file. Provide an accompanying Circle.javafile. Specifically, your Circle class should contain:• One instance variable – radius• A method named setRadius that assigns the passed-in radius value to the radiusinstance variable.• A method named initialize that prompts the user for a radius value and thenassigns the entered value to the radius instance variable.• A method named printCircleData that uses the circle’s radius to calculate thecircle’s diameter, circumference, and area. Use the Java API constant Math.PIfor the value of π. Print the circle’s radius, diameter, circumference, and area. Thereare many ways to implement printCircleData. In the interest of gainingexperience with local variables, declare and use local variables for storing thecircle’s diameter, circumference, and area. The Driver:/***************************************************** CircleDriver.java** This is the driver for the Circle…Modify the NumbersDemo application whose main() method holds two integer variables. Assign values to the variables. In turn, pass each value to methods named displayTwiceTheNumber(), displayNumberPlusFive(), and displayNumberSquared().

- Using Java, Create a JFrame application with a textfield and an OK button. The user types in a number, and presses "OK", your application will get that text, convert it to an int, and display the square of that number in a messagedialog.Which of the methods below is a correct implementation of the functionality described in this Javadoc comment? /** * This method returns a value that is twice as large as the provided * integer argument. * * @throws IllegalArgumentException if the provided number is negative. */ Group of answer choices public int increase1(int number) throws IllegalArgumentException { return number * 2; } public int increase(int number) { try { if (number < 0) { throw new IllegalArgumentException(); } else { return number * 2; } } catch (IllegalArgumentException e) { System.out.println("Negative number!"); } } public int increase(int number) { if (number < 0) { throw new IllegalArgumentException(); } return number * 2; } public int increase(int number) { if (number >= 0) { return number * 2; } else { return IllegalArgumentException; } }1. Create a project in NetBeans and name the project Hw06. 2. The class will contain the following static methods: reverseS – A method that displays a string reversely on the console using the following signature: publicstaticvoidreverseS(Strings) printSub1 – print all substrings of a string NOTE: duplicated substrings are allowed, but loops are not allowed The method signature: public static void printSub1(String s) printSub2 – print all substrings of a string NOTE: duplicated substrings are not allowed, but loops are allowed The method signature: public static void printSub2(String s) Note: All methods should be RECURSIVE. Any predefined classes that are based on Set are not allowed. In the main method, read a string from the user and output the reversed string and substrings to the screen: Sample Run: Please input a string: abcdThe reversed string: dcbaThe substrings of the input string: abcd abc ab a b bc b c bcd bc b c cd c d The substrings of the input string: a ab abc abcd b…
