Question
Project Inheritance-java
Develop a Person class, that has the name, address, physical description (weight, height, eye color), gender, date of birth, age (to be calculated based on date of birth).
Have a class US Citizen that inherits the Person class (have a Boolean attribute, if true then generate a SSN automatically, otherwise make the SSN = 999 99 9999)-it is your choice to have the SSN as a String or an integer.
Develop two more classes Student and Teacher that both inherit US. Citizen class.
For the student class, has a student ID (generated automatically with every intention to an object), number of courses taken, an array listing the names of the courses taken by the student (an array of Strings) and the grade for each course (an array of int), the overall GPA for the student.
For the teacher class, we need an ID (generated automatically –like the student ID but make it start from a different number than the student), and number of Courses, and the names of the courses that this instructor is teaching.
Write a driver that tests the Student and the Teacher classes by instantiating different objects using default values, and asking the user to enter the information, and outputting the information for each object before and after modification.
If the student is not a US. Citizen then insert which visa does s/he have, using the following information
F1 Visa
Academic Studies
The "F" visa is for academic studies. An F1 visa is issued to students who are attending an academic program or English Language Program. F1 visas are by far the most common form of international student visa in the U.S. F1 students must maintain the minimum course load for full-time student status. F-1 status allows for part-time, on-campus employment (fewer than 20 hours per week). Additionally, students can work on optional practical training (OPT) for up to one year after completion of their academic program. Students are expected to complete their studies by the expiration date on the I-20 form (Certificate of Eligibility for Nonimmigrant Student Status).
J1 Visa
Practical Training
A J1 visa is issued to students who need to obtain practical training that is not available in their home country to complete their academic program. J-1 student status allows for similar employment as the F-1
visa, with similar restrictions, as long as permission is given by the exchange visitor program sponsor.
M1 Visa
Non-Academic / Vocational Studies
An M1 visa is issued to a student who is going to attend a non-academic or vocational school. M-1 visa holders for technical and vocational programs are not permitted to work during the course of their studies. The M-1 student visa applicants must have evidence that sufficient funds are immediately available to pay all tuition and living costs for the entire period of intended stay.
You can include the visa information in the Citizen class. Remember, we will assume that in order to be able to work in the united state you must be a US. Citizen.
Draw UMLfor each class and show the relationship between classes. Draw the UML for every instantiated object.
You must have the setters and getters to all attributes in all classes You must have a toString method in every class
Have a default constructor for every class, and at least one overloaded constructor for every class. Use Super as needed.
Validate a user’s entry when applicable.
Document your code properly. (Don’t forget @override when overriding)
