Complete the convert() method that casts the parameter from a double to an integer and returns the result.Note that the main() method prints out the returned value of the convert() method. Ex: If the double value is 19.9, then the output is: 19 Ex: If the double value is 3.1, then the output is: 3 code: public class LabProgram { public static int convert(double d){ /* Type your code here */ } public static void main(String[] args) { System.out.println(convert(19.9)); System.out.println(convert(3.1)); }}
Charge Account Validation Using Java programming Create a class with a method that accepts a charge account number as its argument. The method should determine whether the number is valid by comparing it to the following list of valid charge account numbers:5658845 4520125 7895122 8777541 8451277 13028508080152 4562555 5552012 5050552 7825877 12502551005231 6545231 3852085 7576651 7881200 4581002These numbers should be stored in an array. Use a sequential search to locate the number passed as an argument. If the number is in the array, the method should return true, indicating the number is valid. If the number is not in the array, the method should return false, indicating the number is invalid.Write a program that tests the class by asking the user to enter a charge account number. The program should display a message indicating whether the number is valid or invalid.

In python and include doctring: 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 that takes a Movie…
