- Methods are functions that belong to a class. Explain the concept of function definitions outside a class using the following scenario:A University needs to calculate the fees of students. Explain the required class and function definition outside the class clearly writing a program.MindTap: In C#, Write a program named Averages that includes a method named Average that accepts any number of numeric parameters, displays them, and displays their average. Test your function in your Main(). Tests will be run against Average() to determine that it works correctly when passed one, two, or three numbers, or an array of numbers.Method Overloading is a feature that allows a class to have two or more methods having same name, if their argument lists are different. Argument lists could differ in: 1. Number of parameters. 2. Data type of parameters. 3. Sequence of Data type of parameters. Write different version of method sum() that display the sum of the values received as parameter according to the following main method content: public static void main(String[] args) { sum ( 10, 10 ); sum ( 10, 10, 10 ); sum ( 10.0, 10.0 ); sum ( 10, 10.0 ); sum ( 10.0, 10); } You have to define five functions with the specified types. Then, demonstrate the Argument Promotion concept by reducing the number of method to two.
- 2) Two integers are said to be relatively prime if their greatest common divisor (GCD) is one. For example 12 and 13 are relatively prime, but 12 and 14 are not. a. Write a method called relativelyPrime that accepts two integer parameters A and B. The method should output if A, and B are relatively prime or nat. Use the following method header: public static void relativelyPrime(int A, int B) b. Write a test program (main) to test the method by asking the user to input two positive integers X and Y. Then the program will call the method relativelyPrime to output if X and Y are relatively prime or not. Sample Run 1: Enter Two positive integers X and Y: 12 13 12 and 13 are relatively prime Sample Run 2: Enter Two positive integers X and Y: 12 14 12 and 14 are not relatively primeNOTE: JAVA language Write a program that asks the user for his first name and then prints it using a function/method called printName(). We do not expect the first name to exceed 20 letters. Then the program should print the name with a space between each character. Example: if the first name is Maryam, the :program will print Maryam -1 Maryam -23) Write a program called AveMethod (main method) that contains a method called threeAve (method name) that computes the average of three numbers. NO CREDIT if a method is not used. (7 pnts) a) The main method will do the following: asks the user for 3 number (double type). calls the threeAve method print the average of the three numbers b) The threeAve method will do the following: receives 3 numbers (parameters) calculate the average of the three numbers returns the average ● Sample Run: Input the first number: 2.5 Input the second number: 3.5 Input the third number: 6.6 The average is 4.2 Submission ● Copy and paste your code Screen shot the console with the same Sample Run as above
- Please include doctring, and write only in python: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie…PART B: JUnit Testing Write a Java program according to the following: Create a Multiple.java class. Create the following two static methods (with return type float): SquareRoot() and CubeRoot(). SquareRoot) method should take two arguments and return the float value at the end. CubeRoot() method should take three arguments and return the float value at the end. Create a test class with the name MultipleTest.java. In this class, import the following libraries at the top of this file import org.junit. Before; import org.junit. Test; import static org.junit.Assert.assertEquals; Create an object of Calculator.java class by writing the following code in CalculatorTest.java class: private Multiple multiple; @Before public void setup() {this.multiple new Multiple():) 4. Generate the JUnit test classes for both the methods one by one. Declare and initialize the required variables to pass those to the methods. Store the expected result in one of the variables and then compare it with the…Need help with part B the decode method AND the getChoice method using try/catch The program with the main method should be called ‘LetterCode.java’ The program with the class for performing the operations should be called LetterCodeLogic.java. The class should have two static methods: Encode and Decode (both of which receive a string parameter). Part A: The part A program will be the Encode function Part B: The Part B program will be the Decode function. This is my code so far for LetterCode.java: package lettercode; import business.LetterCodeLogic;import java.util.Scanner; /** * * @author Sean Jeffries */public class LetterCode { static Scanner sc = new Scanner(System.in); public static void main(String[] args) { int choice; String msg="", result=""; System.out.println("welcome to the Letter Code Program!"); choice = getChoice(); while (choice != 0) { switch (choice) { case 1: //encode…
- // The language is java Part I: Use of recursive method (4 points for students who need recursion/extracredit) Description: Code a class called RecursiveMultiply in which it will accept two integer arguments entered from user; pass these integers to a recursive method that returns the multiplication result of these two integers. The multiplication can be performed as repeated addition, for example, if two integers are 7 and 4: 8 * 4 = 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 You will write the application with GUI and recursion to display the result in a noneditable text field, based on the user’s entry from two text fields, while an OK button is pressed. You will utilize the exception handling code as you did in your Lab 4 and Lab 5 to verify if data entered in the text fields are valid (numerical and positive data only). You will make your own decision if there is any explanation that is not described in this specification. Finally, code a driver program that will test your class…T/F The body of a method may be empty1) Through BlueJ, write if the current number of shoppers is greater than or equal to the number leaving then the number of shoppers is decreased by the number leaving. Otherwise, the following error message must be printed and the number of shoppers present must be set to 0. There is an error in the number of shoppers. Use System.out.println to print the message. 2) The class must define a method called leaving that takes a single integer parameter. This represents the number of shoppers leaving the club at a particular point. You may assume that the parameter's value will always be greater than zero and you do not have to check for that. If the current number of clubbers is greater than or equal to the number leaving then the number of clubbers is decreased by the number leaving. Otherwise, the following error message must be printed and the number of clubbers present must be set to 0. There is an error in the number of shoppers. Use System.out.println to print the error message. 3)…
