- Create java code a new class called "Module" in which you add the following attributes: Code Name Number_students 2.Create another class called principle_program in which you create two instances of the class Module called ITP and POP. class principle_program { public static void main(String args[]) { //create two instances of the class Module } }Java script. class Chameleon { static colorChange(newColor) { this.newColor = newColor; return this.newColor; } constructor({ newColor = 'green' } = {}) { this.newColor = newColor; } } const freddie = new Chameleon({ newColor: 'purple' }); console.log(freddie.colorChange('orange'));.java An instance variable declared as static is "common" to all objects of the class. Choose one of the options:TrueFalse
- Charge Account ValidationCreate 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.JAVA Programming Problem 3 - Book A Book has such properties as title, author, and numberOfPages. A Volume will have properties such as volumeName, numberOfBooks, and an array of book objects (Book [ ]). You are required to develop the Book and Volume classes, then write an application (DemoVolume) to test your classes. The directions below will give assistance. Create a class called Book with the following properties using appropriate data types: Title, Author, numberOfPages, Create a second class called Volume with the following properties using appropriate data types: volumeName, numberOfBooks and Book [ ]. The Book [ ] contains an array of book objects. Directions Create a class called Book with the following properties using appropriate data types: Title, Author, numberOfPages, The only methods necessary in the Book class, for this exercise, are the constructor and a toString(). Create a second class called Volume with the following properties using appropriate data types:…Using Java Language: DESCRIPTION The goal is to create a library called DisneyPlus, which hosts Movies and Books, and then to be able to view information such as the best movie (based on score), the most expensive book, all the movies in which an actor has acted.

- INVENTORY CLASS You need to create an Inventory class containing the private data fields, as well as the methods for the Inventory class (object). Be sure your Inventory class defines the private data fields, at least one constructor, accessor and mutator methods, method overloading (to handle the data coming into the Inventory class as either a String and/or int/float), as well as all of the methods (methods to calculate) to manipulate the Inventory class (object). The data fields in the Inventory class include the inventory product number (int), inventory product description (String), inventory product price (float), inventory quantity on hand (int), inventory quantity on order (int), and inventory quantity sold (int). The Inventory class (java file) should also contain all of the static data fields, as well as static methods to handle the logic in counting all of the objects processed (counter), as well as totals (accumulators) for the total product inventory and the total product…java code"User interface" create a main class called MainUI code a method called startRobots,which will decleare and initialise the following 2 robots:kuratas 1350 and megabot 1700 print the toString to display the details of both robots to the user(use JOptionpanel) code a method called startBooks which will create the following two instances of books and display them to the user (using JOptionpane) title:hello world,author:ada,copies:120 title:it ,author;study ,copies:1 in the main method write code to display a menu option prompting the user to choose which program to run as follows press 1 to view:Robots press 2 to view:Books press 0 to: Exitjava code Problem : Bank Account Details Super Class : Account Attributes : customerid , customerame , balance , account Methods : 1-Read the account details 2-Display the Account details Sub class : Bank Attributes : deposit amount , withdraw the amount Methods : 1-Set the deposit amount and return the deposit amount 2-Set the withdraw amount and return the withdraw the amount 4- Display the Bank details

Parameterized constructor…subject :- object oriented programming python assume a typical luggage contains shirts, jackets, pants, and socks, among other items. It may also include DVDs with operating systems such as Windows 11, Ubuntu Linux, and MacOS. It can also store games and movie DVDs in addition to software DVDs. It could also include some basic hardware tools like a hammer, screwdrivers, and scissors. You'll design classes for the luggage object and the objects it holds using an object-oriented approach. Except for abstract classes, each class should include at least one attribute and one feature method (a unique function that belongs to that class, such as cut() in the Scissor class). Keep in mind that for objects with similar features and behaviors, you should attempt to design abstract classes. Define suitable class relationships like aggregation, composition, and association as well. Create a UML class diagram to represent your classes and their relationships.
