New Code

[Brook Esper]

Can someone tell me how to get all the names printed? My program prints only one name, but I want all the names to be printed.

Course class

// Course class
public class Course {
 
	// Data fields
	private String courseName;
	private String[] students = new String[100];
	private int numberOfStudents;
	
	// Constructs 
	public Course (String courseName) {
		this.courseName = courseName;
		
	}
	
	// Methods 
	public String getCourseName() {
		return courseName;
	}
	
	
	public void addStudent(String student) {
		students[numberOfStudents] = student;
		numberOfStudents++;
		
	}
	
	public void dropStudent(String student) {
		
	}
	
	public String[] getStudents() {
		return students;
	
	}
	
	public int getNumberOfStudents() {
		return numberOfStudents;
	}
	
	
	
}

TestCourse

public class TestCourse {

	public static void main(String[] args) {
		Course course1 = new Course("Data Structures");
		Course course2 = new Course("Database Systems");
		
		course1.addStudent("Ben Johnson");
		course1.addStudent("Mary March");
		course1.addStudent("Nora Bently");
		
		course2.addStudent("John Tailor");
		course2.addStudent("Sara Gardner");
		
		System.out.println("Number of students in Data Structure Course is: " + 
		                      course1.getNumberOfStudents());
		
		String[] students = course1.getStudents();
		for (int i = 0; i < course1.getNumberOfStudents(); i++);
		    System.out.print(students[i] + ", ");
		    
		    System.out.println();
		    System.out.print("Number of students in Database Systems is: " + 
		                       course2.getNumberOfStudents());
		    		
		    	
	}		

}

Take a look at you for loop in TestCourse.

Ok and?

[Knute Snortum]

You have the printlns indented under the for loop, but are they really controlled by the loop?

How can I fix it?

[Ganish Patil]

for (int i = 0; i < course1.getNumberOfStudents(); i++);

remove this semicolon, here loop doesn't reach to below code. scope of int i is limited to loop circular bracket so can't access here

System.out.print(students[i] + ", ");

so declare int i before the loop.

Look at this tutorial then if you can't figure it out, look below:

Remove the semicolon at the end of the for() line and put braces {} around the lines controlled by the for loop.
