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.
Overview:A new bank wants to make a simple application to keep track of all accounts and transactions.In this TMA, it is required to help the bank manager implement the required application.Requirements:After a quick meeting with the bank manager, you got the following information: It is required to store all bank accounts in one collection and all the transactions happenedin another collection. Each account has a unique account number, a holder and balance. There is a specific prefix(common for all accounts) that should be added to the holder's civil id to create the uniqueaccount number. In addition, it is not allowed for a holder to have more than one account.Furthermore, only three transactions are allowed on any account: deposit, withdrawal andtransfer money to another account. Each holder has a unique civil ID (national id), a name and other attributes (add at least 2attributes from your choice). For each transaction, it is required to store the account(s) affected, amount of…

Suppose that an application declares an array of class objects with the following statement: Employee[] employees = new Employee[9]; Write a loop that creates 10 instances of the class and assigns them to the elements of the array.
The class Name consists of 4 instance data, String title, String first, String middle, and String last. The class has a constructor that is passed all 4 String values and initializes the class appropriately. It has 4 methods and each returns one of the four instance data, called returnTitle (), returnFirst(), returnMiddle and returnLast(). Name [] addressBook = new Name[100]; is performed. It is then used to store n entries (n is an int). Write a method that is passed 4 String parameters corresponding to the title, first, middle, and last of Name, and finds this Name in addressBook and returns the index of where this Name was found, or -1 if the Name was not found. Assume that addressBook stores n entries (n is an int).

Create the StockTask1 Java project Create a Stock object class that contains the following information: The symbol of the stock is stored in a private string data field called symbol. The stock's name is stored in a private string data field called name. previousClosingPrice is a private double data area that stores the stock price for the previous day. currentPrice is a private double data area that stores the stock price at the current time. A constructor for creating a stock with the given symbol and name. For the data fields, there are accessor methods (get-methods). For the data fields, there is a mutator method (set-methods). A method named getChangePercent()that returns the percentage changed from previousClosingPrice to currentPrice. Formula:perc_change = (current price - previous closing price) / previous closing price x 100 Create a test class named testStockthat creates a Stockobject with the stock symbol SUNW, the name Sun Microsystems Inc., and the previous closing…
Develop a Java application that implements Remote Method Invocation (RMI) for the Pearson Institute of Higher Education. The application should allow the user to enter their details to a user interface and these details should then be saved to a database. The Java application must consist of the following: A database:The database should be called registrants, and should have a table called students with the following table properties: idNumber, name, surname, age, cellnumber, degree; A server object interface:This interface should be called ConnectInterface and must have a method called Insert() which will be used to insert the parameters obtained from the GUI. ConnectionImplement class:o The class should be called ConnectionImplement and should implement the ConnectInterface interface.o It should have a method to get the all the student details from the GUI and populate them to the registrants database using the method defined in the ConnectInterface interface.o The method should…
