Project

In this project you will implement an in-memory, i.e. nothing will be written to or read from disk b, student information system. For this purpose create a class with the following attributes none of which can be accessed out of the class.

• id: attribute to store student id, type will be integer
• name: attribute to store student name, type will be string
• surname: attribute to store student surname, type will be string
• gpa: attribute to store student gpa, type will be double.

Implement the following helpers for the class, determine the return types based on the semantic of the helper. Helper names are self explanatory, i.e. setName(s) assigns value of s to name attribute of the object and getName() returns name value of the object.

• student(id, name, surname, gpa): constructor
• setName(string s)
• setSurname(string s)
• setGpa(double s)
• setId(int s)
• getName()
• getSurname()
• getGpa()
• getId()

==================================

To store single student's information you need an object of type student.

To store information of multiple students you need to use array list. To use array lists you need to import java.util.ArrayList

Later you can use the following definition to store information for multiple students:

static ArrayList <student> studentList = new
ArrayList<student> ();
BONUS!!!

Add a new menu item "Sort Students by Name" which will sort the arraylist based on the student name
