 make a University  app to have a simple system to keep track of all the students (graduate  and undergrads).To do that the following classes are needed for this  object-oriented database.

Student

• StudentID : Integer
• stdFirstName: String
• stdLastName: String
• stdMarks : Double []
• stdAddress: Address

** Class Student should have set/get properties, constructor and have following methods:

Average() - that returns the average grade for students

toString() method that returns the above information as a String

1. A class called Address which can be that can be added into the class student

Address

• streetInfo: String
• city: String
• postalCode: String
• province: String
• country: String

** Class Address should have set/get properties, constructor and following method:

toString() method that returns the above information as a String

1. A class called UndergraduateStudent that inherits from Student and has the following members:

Undergrad Student

• subject: String
• yearOfEntry :Integer

***Class Student should have set/get properties, constructor and following method:

Graduate()  - Boolean that returns true if the Student is eligible to graduate when  the average of their marks is greater than 50.

toString() method that returns the above information as a String

1. A class called GraduateStudent that inherits from Student and has the following members:

Graduate Student

• subject : String
• yearOfEntry :Integer
• thesisTopic: String

Class Student should have set/get properties, constructor and following method:

Graduate()  - Boolean that returns true if the Student is eligible to graduate when  the average of their marks is greater than 70.

toString() method that returns the above information as a String

Summary of Operations

System Menu:

1. Add undergraduate student
2. Add graduate  student
3. View all the students
4. View only eligible students for graduation
5. exit

Overview:

• You may use array or ArrayList to store all your students(graduate and undergrad) into one array of objects.
• If you use an Array, you may assume the user does not enter more than ten students in total into the system

1 -Add undergraduate Students: this  menu should accept all the necessary parameters for undergraduate  students and create an instance from undergraduate class and store it  into students array.

2 -Add graduate student:  this menu should accept all the necessary parameters for graduate  students. It should create an instance from the graduate class and store  it in the students' array.

3- View all the students: view all the relevant information of students (graduate and undergraduate) from students array

4- View only eligible students for graduation: view all the relevant information (graduate and undergraduate) from the students' array only if they are eligible to graduate.

5 - Exit: exit the running menu (program)
