Question

Exercise 1: Students Records Develop a java program that saves 3 students records using array of objects. Each contains student name, age and GPA. In the main class, use arrays of objects, methods, for loop to print Student Record and set both age and GPA. Use 2 interfaces (printable, changeable) that has all methods needed as abstract. The following is detailed hierarchy content: Changeable interface: Methods: Method to update age of certain student object array Method to update GPA of certain student object array Printable interface: Method: Method that prints the array of object containing the student record Student class: Attributes: 3 array of objects given Object class type (each holding student name, age and GPA) Methods: Interfaces' methods fully implemented & main method to test the program Test Scenario: 1- Print all 3 students 2- Change the age and GPA of student 1 then reprint it Hierarchy: Printable Interface Changeable Interface Class (3 arrays, 3 methods)

          Exercise 1: Students Records
Develop a java program that saves 3 students records using array of objects. Each contains student
name, age and GPA. In the main class, use arrays of objects, methods, for loop to print Student Record
and set both age and GPA. Use 2 interfaces (printable, changeable) that has all methods needed as
abstract. The following is detailed hierarchy content:
Changeable interface:
Methods:
Method to update age of certain student object array
Method to update GPA of certain student object array
Printable interface:
Method:
Method that prints the array of object containing the student record
Student class:
Attributes:
3 array of objects given Object class type (each holding student name, age
and GPA)
Methods:
Interfaces' methods fully implemented & main method to test the program
Test Scenario:
1- Print all 3 students
2- Change the age and GPA of student 1 then reprint it
