uestion 1: Write a java program for a simple calculator. The program accept two numbers from user. The program consists from four classes are add, sub, mul and div. For each class, two constructors, first with no argument and second with argument. Add class for addition to get addition of two numbers, it include two methods: 1. Operation method with two parameters 2. To print result and to give a description for the method Sub class to do subtraction and it's inherit from Add class and it include 1. Operation method with two parameters 2. To print result and to give a description for the method 3. Overriding the print method " show it for subtraction" Mul class to do multiplications and it's inherit from sub class and it include 1. Operation method with two parameters 2. To print result and to give a description for the method 3. Overriding the print method " show it for multiplication" div class to do division and it's inherit from mul class and it include 1. Operation method with two parameters 2. To print result and to give a description for the method 3. Overriding the print method " show it for division" Vrite the main methods to show the results for each class and description for the method

6. Design a Java class with a main method that does the following. You must include a meaningful comment for main and each method a. Main invokes a method readScores to read input from a file (name of your choice) that contains the name of the bowlers (no more than 25) and their bowling scores (two scores per bowler). The program stops reading values when it has reached the end of the file. For example, the file might contain: Bob 203 176 Jane 210 253 Jack 300 189 Eileen 220 298 • As the method reads the data, it stores the name into a String array and the average of the two bowling scores into an array of double. • The method returns the actual number of bowlers read in b. Main then invokes a method computeOverallAvg to: compute (a) the overall average score of all the bowlers combined, (b) the average score and name of the bowler with the highest average score and (c) the average score and name of the bowler with the lowest average scores. print to the console (a) the overall average…

Write a python code for both 1 and 2 use random inputs for each variable

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…
