write a program in java containing two classes named student and roster, respectively. The program will maintain a current roster of students within a given course. Student data for the program includes student ID, first name, last name, e-mail address, age, and array of grades. The program you create will read a list of five students, with one of the students being yourself, and use the series of method calls below (see part B3 below). A well-designed program would use the principles of encapsulation and information hiding. Here is the data that will be used from within the main method of your program:
| Student ID | First Name | Last Name | Age | Grades | |
| 1 | John | Smith | John1989@mail.com | 20 | 88, 79, 59 |
| 2 | Suzan | Erickson | Erickson_1990@mail.com | 19 | 91, 72, 85 |
| 3 | Jack | Napoli | The_lawyer99@yahoo.com | 19 | 85, 84, 87 |
| 4 | Erin | Black | Erin.black@comcast.net | 22 | 91, 98, 82 |
| 5 | Your first name | Your last name | Your valid e-mail address | 21 | 92, 88, 95 |
Requirements:
A. Include your personal information in the last item of the table above.
B. Create a program that uses the information in the table above to create an ArrayList of Student objects. For the Student object class, do the following. 1. Include the following instance variables that describe each student:
student ID
first name
last name
e-mail address
age
array of grades
2. Include the following methods in the Student class:
a. an accessor (i.e., getter) for each instance variable from part B1
b. a mutator (i.e., setter) for each instance variable from part B1
Note: All access and change to the instance variables of the Student class should be through accessor and mutator methods.
c. constructor using all of the input parameters
d. print() to print specific student data (e.g., student ID, first name, last name) using accessors (i.e., getters)
Note: Printing out the grades is optional, not required.
3. Create a student Roster class with the following methods that contain all ArrayList method calls:
a. public static void remove(String studentID) that removes students from the roster by student ID
Note: If the student ID doesnt exist, the method should print an error message indicating that it is not found.
b. public static void print_all() that prints a complete tab-separated list of student data using accessor methods
Note: Tabs can be formatted as such: 1 [tab] First Name: John [tab] Last Name: Smith [tab] Age: 20 [tab] Grades: {88, 79, 59}. The print_all() method should loop through all the students in the student array list and call the print() method for each student.
c. public static void print_average_grade(String studentID) that correctly prints a students average grade by student ID
d. public static void print_invalid_emails() that verifies student e-mail addresses and displays all invalid e-mail addresses to the user
Note: A valid e-mail should include an at sign (@) and period (.) and doesnt include a space.
C. Demonstrate the programs required functionality by running the following scenario: print_all(); print_invalid_emails(); //loop through the ArrayList and for each element: print_average_grade(current_loop_student); remove("3");
remove("3"); //expected: this should print a message saying such a student with this ID was not found.
1. Submit evidence of the programs required functionality by attaching the output along with the entire (zipped) project folder.
Note: The program may be created in any IDE, but BlueJ or NetBeans are recommended for faster evaluation.
