TestDriver is given for the other image.Design a new Account class as follows:■■ Add a new data field name of the String type to store the name of thecustomer.■■ Add a new constructor that constructs an account with the specified name, id,and balance.■■ Add a new data field named transactions whose type is ArrayList thatstores the transaction for the accounts. Each transaction is an instance of theTransaction class, which is defined as shown in Figure ■■ Modify the withdraw and deposit methods to add a transaction to thetransactions array list. Write a test program that creates an Account with annual interest rate 1.5%,balance 1000, id 1122, and name George. Deposit $30, $40, and $50 to theaccount and withdraw $5, $4, and $2 from the account. Print an account summarythat shows the account holder name, interest rate, balance, and all transactions.Decision Structures Do this for jGrasp This program will calculate the cost of having a framed picture for customers. After the customer enters the appropriate prompted values, the program will calculate the cost of the framing based on the specifications outlined below. The program should allow the user to order a second frame if desired. Define a java instance class as described below. Save the class definition in a file with an appropriate filename. Class Name: Frame Instance Variables: length – float (representing inches) (Fields) width – float (representing inches) type – char (valid values P, W, or M for Plastic, Wood, or Metal) matte – integer (representing the number of matting layers) Static Variable: count – tracks the number of frames created Instance Methods: A constructor that accepts no arguments and sets default values as follows: the length to 8,…
- Project in Java programming language : Choose an enterprise and do a business description of it. 1-2 pages. Create all classes for entities. All classes must have at least a constructor, get and set methods for all private variables and a toString method. Create classes also for connection entities (e.g. orders, reservations, etc.) All information should be saved in files. When opening the program, all information from files must be loaded in array lists. Use an array list for every class. The program must have at least one menu where the user can choose the operations to work. You should at least have one class that inherits from another class. You should have at least one interface that is extended by at least 2 classes. You must use the interface methods in your program. You are allowed to use the GUI for this project. If not use JOptionPane You are allowed to use databases, instead of files.Language - Java Create a utility class called DuplicateCounter. Create an instance method called count that takes a single parameter called dataFile (representing the path to a text file) and uses a Map of Strings to count how many times each word occurs in dataFile. The counts should be stored in an instance variable called wordCounter. Create an instance method called write that takes a single parameter called outputFile (representing the path to a text file) and writes the contents of wordCounter to the file pointed to by outputFile. The output file should be overwritten if it already exists, and created if it does not exist. Create a separate class called Application that contains a main method which illustrates the use of DuplicateCounter by calling both the remove and write methods. Your input file must be called problem2.txt and your output file must be called unique_word_counts.txQ2 Create MusicOrganizer project using BlueJ . (i) Create a MusicOrganizer class and declare an ArrayList for storing the file names of music files into the String object. (ii) Create a constructor for the music organizer class and assign the field to the ArrayList. (iii) Write a method to add a file to the collection. (iv) Write a method to return the number of files in the collection. (v) Write a method to remove a file from the collection. (vi) Make a screen shot of the coding and output.
- Implement a PowerSeller class that is derived from the Seller class. Create the powerseller.h andpowerseller.cpp files for this class. This derived class contains additional data members include:o the seller’s own web site address (string),o number of items sold in the current year.Methods included in this derived class are:• A default constructor and a copy constructor• A value constructor that receives all data for a power seller• Appropriate get and set functions for the new data• print() – overrides the parent class print() method. This method should call the Sellerclass print method to display all the information from a Person class and the seller class,and also display the additional power seller data with appropriate messages.• read() – overrides the parent class read() method. This method should call the Seller classread method to read all the information for Person class and seller class, and also read inthe information for the specific data for a Power Seller. The addition…Define a Student class, with 3 data fields: ID: string Name: string FavoriteThing: string Create an application that stores and outputs a list of the students' favorite things.

- Books can come in various formats, like paper books, audio books, ebooks, etc. Create a generic classBook that has as common attributes the title, the year of publication, and the author. The constructor of thisclass should instantiate all three attributes. Override the toString method of class Book that returns a stringthat contains the values of its attributes. Create a subclass PrintBook that extends Book with attributesPublisher and ISBN. Create another subclass AudioBook which has the book’s size (in MB), its playlength and the playback artist’s name as attributes. Both PrintBook and AudioBook classes override thetoString method inherited from Book. Write a Java application to demonstrate the usage of this hierarchy.In an n-sided regular polygon, all sides havethe same length and all angles have the same degree (i.e., the polygon is both equilateraland equiangular). Design a class named RegularPolygon that contains:■■ A private int data field named n that defines the number of sides in the polygon with default value 3. ■■ A private double data field named side that stores the length of the side withdefault value 1.■■ A private double data field named x that defines the x-coordinate of the polygon’scenter with default value 0.■■ A private double data field named y that defines the y-coordinate of the polygon’scenter with default value 0.■■ A no-arg constructor that creates a regular polygon with default values.■■ A constructor that creates a regular polygon with the specified number of sidesand length of side, centered at (0, 0).■■ A constructor that creates a regular polygon with the specified number of sides,length of side, and x- and y-coordinates.■■ The accessor and mutator methods for all data…Match the following: This keyword is to declare a user-defined package.
