Chapter 5. PC #17. Rock, Paper, Scissors Game (page 317) Write a program that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows. 1. Add the following two lines to the beginning of your main method. This will allow your computer choices match with the test cases here in HyperGrade. long seed = Long.parseLong(args[0]); Random random = new Random(seed); 2. When the program begins, a random number in the range of 0 through 2 is generated. If the number is 0, then the computer has chosen rock. If the number is 1, then the computer has chosen paper. If the number is 2, then the computer has chosen scissors. (Do not display the computer choice yet.) 3. The user enters his or her choice of "rock", "paper", or "scissors" at the keyboard. You should use 1 for rock, 2 for paper, and 3 for scissors. Internally, you can store 0, 1, and 2 as the user choice, to match with the above schema. 4. Both user and computer choices…
Complete the Course class by implementing the courseSize() method, which returns the total number of students in the course. Given classes: Class LabProgram contains the main method for testing the program. Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here.) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. Ex. For the following students: Henry Bendel 3.6 Johnny Min 2.9 the output is: Course size: 2 public class LabProgram { public static void main (String [] args) { Course course = new Course(); // Example students for testing course.addStudent(new Student("Henry", "Bendel", 3.6)); course.addStudent(new Student("Johnny", "Min", 2.9)); System.out.println("Course size: " + course.courseSize()); } } public class Student { private String first; // first name private String last; // last name private…
Write a method for the farmer class that allows a farmer object to pet all cows on the farm. Do not use arrays.
53. Write a class with two instance variables, representing an old password and a new password. Write a recursive method that returns the number of places where the two passwords have different characters. The passwords can have different lengths. Write another, nonrecursive method returning whether the two passwords are sufficiently different. The method takes an int parameter indicating the minimum number of differences that qualify the passwords as being sufficiently different. Your program should include a client class to test your class.
Create another class DayProg and write the main() method to display the following: Today is 2022-02-03. The Daylight-Saving Time start day is 2022-03-13. There are 38 days until the Daylight-Saving Time start day. The date after 19 days is: Year : 2022 Month: 2 Day : 22
Using python: (see attached- I need help with part Q2) Add a method to the person class name it (username) that takes the email and take off all the part from @ and after, and assigns the string before the @ sign to a variable username. For example: malabdullah@UT.edu, the method will assign 'malabdullah' as the username.
This is for python class, so please answer in python 9.12 LAB: Product class In main.py define the Product class that will manage product inventory. Product class has three attributes: a product code, the product's price, and the number count of product in inventory. Implement the following methods: A constructor with 3 parameters that sets all 3 attributes to the value in the 3 parameters set_code(self, code) - set the product code (i.e. SKU234) to parameter code get_code(self) - return the product code set_price(self, price) - set the price to parameter price get_price(self) - return the price set_count(self, count) - set the number of items in inventory to parameter count get_count(self) - return the count add_inventory(self, amt) - increase inventory by parameter amt sell_inventory(self, amt) - decrease inventory by parameter amt

First, implement a python class called Student. This class should store 2 variables, name and grade. Later, implement a class called Classroom. The constructor of this class should input the list of students in this classrom. This class should also contain 3 methods, add_student, remove_student and calculate_stats. As the names suggest, add_student method should input a Student object and add that to its' already existing student list, remove_student must input a full name(string) and delete the student with the provided name(you can assume no 2 students have the same full name). Finally, calculate_stats method must calculate and print the following statistics of the grades: 1. The name of the student with highest grade and the grade itself. 2. The name of the student with lowest grade and the grade itself. 3. The average grade
