Passing Objects Created By User to Array in Different Class

[Kd Martin]

I have to create two classes: Student and Course. The purpose of the program is to have the user create students and courses and add students and drop them from courses. I was told by my professor to create an array called "Student" in the course class. What I'm having a problem understanding is how to pass the student object created by the user in the class "EnrollStudent" to "Course" to fill the array "Student". If you could help me understand this I would really appreciate it! Thanks!

Student:

public class Student {
	//Data Fields
	private String name; 
	private int UFID;
	private String DOB;
	
	//Number of Students created
	private static int numberOfStudents = 0;
	
	//Constructor
	Student(String name_, int UFID_, String DOB_) {
		name = name_;
		UFID = UFID_;
		DOB = DOB_;
		numberOfStudents++;
	}
	
	//Get and set methods for all properties
	String getName() {
		return name;
	}
	public void setName(String newName) {
		name = newName;
	}
	int getUFID() {
		return UFID;
	}
	public void setUFID(int newUFID) {
		UFID = newUFID;
	}
	String getDOB() {
		return DOB;
	}
	public void setDOB(String newDOB) {
		DOB = newDOB;
	}
}

Course:

import java.lang.*;

public class Course {
	//Data Fields
	private String name; 
	private int capacity; 
	private int currentEnrollment; 
    private Student[] students; //Create array of students in course
	private static int numberOfCourses = 0; //Number of courses created so far
	
	//Constructor
	Course(String n, int cap) {
		name = n;
		numberOfCourses++; 
		capacity = cap;
		currentEnrollment = 0;
		students = new Student[capacity] //Create array
	 }
	
	//Get and set methods
	String getName() {
		return name;
	}
	public void setName(String newName) {
		name = newName;
	}
	int getCapacity() {
		return capacity;
	}
	public void setCapacity(int newCapacity) {
		capacity = newCapacity;
	}
	int getCurrentEnrollment() {
		return currentEnrollment;
	}	
	
	//Add a student to course and return true if added and false if not
	public static boolean addStudent(Student s) {
		if (currentEnrollment < capacity) { 
			students[currentEnrollment] = s; //Add student s to a seat
			currentEnrollment++;
			return true;
		}
		else {
			return false;
		}
	}
	
	/*Method to remove student from a class
	public static void removeStudent(Student s) {
		currentEnrollment--;
	}
	*/
	
	//Print courses a student is in
	public void display() {
		System.out.println("Student name: " + name);
		System.out.println("\t UFID: " + UFID);
		System.out.println("\t DOB: " + DOB);
		
	}
}

Enroll Student:

import java.util.Scanner;

public class EnrollStudent {
	public static void main(String[] args) {
		Scanner input = new Scanner(System.in);
		System.out.println("How many courses would you like to create?");
		int numCourses = input.nextInt();
		
		//Create courses
		if(numCourses > 0) {
			Course[] courses = new Course[numCourses]; //Create array of course objects
			
			for (int i=0; i<numCourses; i++) {
				System.out.println("What is the capacity of Course " + (i+1) + ": ");
				int cap = input.nextInt();
				Course c = new Course(capacity);
				courses[i] = c; //Store in array of courses
			}
		}
		
		else {
			System.out.println("You have to create at least 1 course!");
		}
		
		System.out.println("How many students are there?");
		int numStudents = input.nextInt();
		
		//Create Students
		if(numStudents > 0) {
			//Read student information
			for (int i = 0; i < numStudents; i++) {
				System.out.println("Student's name? "); 
				String name = in.next(); 
				System.out.println("Student's UFID? "); 
				int UFID = in.nextInt(); 
				System.out.println("Student's DOB? (mm/dd/yyyy) "); 
				String DOB = in.nextDouble(); 
			
				Student students = new Student(name, UFID, DOB); 

			} 
		}

First I assume you are getting at least one compilation error for your Course class. The addStudent method should not be static.
Once you've fixed that you will need to call that method to add a student to the course.

The first thing you need to do is find out which course the student is to be enrolled on. Lets assume for the moment it's only going to be one course - we can expand it later to support multiple courses.
Probably the easiest way to do this is to display a numbered list of courses and ask the user to enter the number of the course.
Give that a go and see how far you get. You'll need a for loop to display the list and it needs to go after line 39 where you create the Student object.

Sorry, I forgot to welcome you to the Ranch. Welcome, now

This question looks so similar to your question from yesterday that I shall close this thread; please continue discussion there (even if I did scare you with a long reply there).
