Write two methods: one called largestwhich returns the value of the largest of its three double parameters, and one called smallestwhich returns the value of the smallest of its three double parameters. The program shouldthen display both values with an appropriate message. 5. Data ValidationCreate the following methods that can be used to gather correct data from the user:public static int readValidInt (int low, int high)Returns an integer value that is within the stated range.public static double readValidIDouble (double low, double high)Returns a double value that is within the stated range.

ISBNThis problem is slightly more difficult than the above problem. This one requires a data type that stores 10 digits. BackgroundPublishers and bookstores use a number system called the International Standard Book Number (ISBN) system to identify books. At the start of publication, each book is assigned a unique ISBN. An ISBN, once assigned, can never be re-used. Click here for detailed information on this numbering system.An ISBN consists of exactly 10 digits. The rightmost digit is the check digit. The check digit is validated modulo 11.• multiply each digit from the first to the ninth by a weight from 10 to 2 respectively (the first digit by 10, the second by 9,.., the ninth by 2).• the sum of the products plus the check digit should be divisible without remainder by 11.• if there is a remainder, the whole number is not a valid ISBN SpecificationsDesign a program that validates an ISBN. Your program keeps accepting a whole number and determining if that whole number is a valid…
JAVA Problem description:You are to write a program called Seasons that prompts the user for a month and day and displays the season in which that date occurs. For reference, we will use the following date cutoffs for the various seasons: Winter December 21 – March 19 Spring March 20th – June 20th Summer June 21st – September 20th Fall September 21st – December 20th Data Validation For this program, you'll write a specific method to perform data validation based on the month and day entered. More specifically: Month – the month entered must be a valid month of the year (January – December). Day – the day entered must be a valid day for that month: January, March, May, July, August, October, December have 1-31 days. April, June, September, November have 1-30 days. February has 1-28 days (do not worry about leap years) Required program decomposition String getMonth(Scanner console) This method is called from the main method and should prompt for the month as a string…
Q6. 1.Using pseudocode, a method that will add two numbers, and return the sum to the calling function. Note that the method will receive two numbers as arguments.
C++ Visual 2019 A particular talent competition has five judges, each of whom awards a score between 0 and 10 to each performer. Fractional scores, such as 8.3, are allowed. A performer's final score is determined by dropping the highest and lowest score received, then averaging the three remaining scores. Write a program that uses this method to calculate a contestant's score. It should include the following functions: void getJudgeData() should ask the user for a judge's score, store it in a reference parameter variable, and validate it. This function should be called by main once for each of the five judges. void calcScore() should calculate and display the average of the three scores that remain after dropping the highest and lowest scores the performer received. This function should be called just once by main and should be passed the five scores. The last two functions, described below, should be called by calcScore, which uses the returned information to determine which of the…
C++ program int quadrant() This method will return at which quadrant does this point lie in our Cartesian plane. You may use the internet to recall your quadrants in the Cartesian coordinate system. This method will return 1 if it is in Quadrant I (+, +), 2 if it is in Quadrant II (-, +), 3 if it is in Quadrant III (-, -), and 4 if it is in Quadrant IV (+, -). If the point lies in the x-axis, return -1. If the point lies in the y-axis, return -2, if the point is in the origin, return 0.

In C# Define 4 methods with the names of addition, subtraction, multiplication and division. In writing methodsThe following points will be taken into consideration. The addition method takes two parameters, one is string and the other is int, anddisplays the result in the message box. This method is used in a namespace called Mathematical Operations.takes place. It takes two string methods into the subtraction method and calculates the result of the back removal operation.returns. This method can be used by creating the object of the class in the class called Operations.Multiplication calculates the multiplication of the number 5 by the number 6 and displays the result in the message box.This method is located in the name space called Carpals. No object is created from the class for use. It takes 5 parameters into the division operation, and each parameter is string, int, double, respectively.string must be int. This method divides each of these parameters in turn and calculates…
Order check Write a program OrderCheck.java that takes four int command-line arguments w, x, y, and z. Define a boolean variable whose value is true if the four values are either in strictly ascending order (w < x < y < z) or strictly descending order (w > x > y > z), and false otherwise. Then, display the boolean variable value.

The International Standard Book Number (ISBN) is a number that uniquely identifies a book. Publishers can buy or receive ISBNs from the International ISBN Agency. There are two types of ISBNs: ISBN-13 and ISBN-10, which are 10- and 13-digits long, respectively.ISBN-10 has a pattern, where the last digit can be found using the first 9. Additionally, ISBN-10 can also be used to calculate its ISBN-13 equivalent (and vice versa). Write two functions in ISBN.java. The main method is implemented for you so you can test your functions. Instructions on how to run this file to make use of the test.txt file are detailed below. calculateISBN10(int[] isbn) computes the last digit of the ISBN-10 number. The first 9 of the 10 digits of the ISBN will be passed to the function as the parameter isbn integer array of size 10. The last integer in the array will be -1. Your job is to calculate the last digit (called the check digit), and update the last index of the isbn array with the computed…
