Java is a computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible.

1 Goals.
1. To use a text file for output and later for input.
2. To use exceptions and write an exception handler that does more than abort execution.
3. To Use a static class variable.
4. To use a boolean variable and a Date variable.
5. To use an ArrayList.
6. To implement Phase 1 of a four phase well-structured project with multiple classes using the Model-View-Controller design pattern (MVC).
2 Overview
This section discusses a finished application that you will construct in several phases. When all phases are finished, it will simulate a human resources system to keep track of savings through the company. There is a Human Resources Manager (Boss), and employees (eventually more than one type of employee will be used). Eventually, this system will be created as an application with a windows interface. The Employee’s login name will eventually be encrypted and the data will be stored in an object file. Program 4 implements only part of the menu, uses a text file and does not encrypt the employee data. At first this will be a menu-driven application allowing for these actions:
1. The first time the program is used, the user will enter his or her own data in to the program and will become the Boss (Human Resources Manager) with access to everyone’s data.
2. After that, when the program starts up, it will read in a database of employee data and store it in the employee collection.
3. After that, the Boss will be able to log in and create new employees by entering the person’s name (first, middle initial-optional, and last), login name, base salary, and savings percent. This data will be used to initialize a new employee object. The object will also record the current date and a unique ID number for this employee. The new employee will be added to the Employee collection.
4. The Boss can log in and display a list of all Employees in the collection and can change the base salary or percent savings for any employee. In the list, display the full name (first, middle initial and last), login name, Employee ID, base salary, percent savings and date of hire for each Employee.
5. Any Employee in the collection can log in and see his or her own data and change their name and percent savings (due to marriage, etc).
6. An Employee whose login name is in the collection may log in and out. Logging in will automatically log out the prior Employee.
7. The menu has an option to quit and quitting will cause the final contents of the collection to be written back to the database file (replacing it).
8. Since you have
more than one class
in this project, you will
need to create a package (call it “savings” – note the first letter is lower case)
and put all of the classes in the package. To tell your program to look for the other classes, you need to put the following in each class file near your import statements.

attempts The cubic_features function in features.py is already implemented for you. That function
can handle input with an arbitrary dimension and compute the corresponding features for the cubic
Kernel. Note that here we don't leverage the kernel properties that allow us to do a more efficient
computation with the kernel function (without computing the features themselves). Instead, here
we do compute the cubic features explicitly and apply the PCA on the output features..
