Write a Java program which will store, manipulate, and print student registration information.
As part of the solution, identify the following classes:
• Student
• Admissions.
The class Student must have the following fields – Name, Address, Id number, Courses, and Date, where:
• Name is a user defined class comprising of at minimum first name and last name.
• Address is a user defined class comprising of fields - street, city, state, and zip code.
• Date is a predefined class in the java.util package
• The field Courses is a set of no more than five (5) string values representing the courses being registered for. Course names supplied are assumed to be valid and contains no blank space, for instance COP3337 is valid but not COP 3337.
• Id number a string variable that uniquely identifies a student.
The class Student must be capable of adding courses and dropping courses
The class Admissions stores and manipulates the student information (student record). Because the list of students grows dynamically, it is best to use a dynamic data structure such as the ArrayList to store the information. This class should do the following, among other possible activities:
• Add student to the list
• Remove student from the list, which would first involve locating the record in order to remove it. In order to determine which record to remove you must supply the Id number as the search argument.
You are to provide a test class that coordinates the activities of the classes outlined above, by:
• Creating student objects and adding them to the database of the Admissions object
• Manipulating student record by:
o Adding a course(s)
o Dropping a course(s)
• Removing a student from the database
• Displaying list of currently registered students
• Displaying list of all students that were dropped from the course
Display the output in a scrollable pane, and must be formatted as follows:

this is the code we have so far but im kind of confused about the whole concept of a tester clas and how its used. could someone revise this code for me and just see if its correct, and if not make adjustements where needed, as well as explain the concept of the tester class and how to implement it in netbeans.

Solution
The interesting part is in main() and the use of Scanner. This solution also uses an ArrayList to store the results, and a for-each loop to iterate through them.
import java.util.*; public class Student { private String m_name; private int m_age; private String m_course; private String m_year; private String m_section; public Student( String name, int age, String course, String year, String section ) { m_name = name; m_age = age; m_course = course; m_year = year; m_section = section; } public String getName() { return m_name; } public int getAge() { return m_age; } public String getCourse() { return m_course; } public String getYear() { return m_year; } public String getSection() { return m_section; } public String toString() { return \"name: \" + m_name + \", age: \" + m_age + \", course: \" + m_course + \", year: \" + m_year + \", section: \" + m_section; } public static void main(String[] args) { ArrayList<Student> students = new ArrayList<Student>(); Scanner input = new Scanner(System.in); int menuChoice = 4; do { System.out.println(\"\\t\\t\\tStudent Record Menu\"); System.out.println(\"\\t\\t1. Add Student\\t2. View Students\\t3. Search Student\\t4. Exit\"); try { System.out.println(\"Enter a choice: \"); menuChoice = Integer.parseInt(input.nextLine()); } catch (NumberFormatException e) { continue; } if (menuChoice==1) { System.out.println(\"Full name:\"); String name = input.nextLine(); int age = -1; do { try { System.out.println(\"Age:\"); age = Integer.parseInt(input.nextLine()); } catch (NumberFormatException e) { System.out.println(\"Enter a number!\"); continue; } } while (age <= 0); System.out.println(\"Course:\"); String course = input.nextLine(); System.out.println(\"Year:\"); String year = input.nextLine(); System.out.println(\"Section:\"); String section = input.nextLine(); Student student = new Student(name, age, course, year, section); students.add(student); } else if (menuChoice==2) { System.out.println(\"Students:\"); for (Student student : students) { System.out.println(student); } } } while (menuChoice<4); } }
We want to call nextLine() to collect an entire line of input at a time. Calling next() will return the next token, and supposing the user enters a series of nnwords (a space delimited list of tokens) it wil
