Need help on finishing this program:
Below is the start of a definition for a Course class. Each Course stores its name, current enrollment, and maximum enrollment. In the class definition, provide a Course constructor and define methods so that the following code will compile:

Course introJava = new Course("Java Programming", 15, 25);
System.out.println("Course currently has " + introJava.getCurrentEnrollment() + " students");
System.out.println("How many students to add?");
Scanner input = new Scanner(System.in);
int moreStudents = input.nextInt();
introJava.addStudents(moreStudents);
System.out.println("Course currently has " + introJava.getCurrentEnrollment() + " students");
if (introJava.overFull()){
System.out.println("too many students!");
}

When the code fragment above is run, the output might look like:

Course currently has 15 students
How many students to add?
18
Course currently has 33 students
too many students!

I started right here with my code:

public class Course
{
private String name;
private int enrollment;
private int max_enrollment;
public course (String nm, int currentEnrollment, int max_ currentEnrollment)
{ 
name = nm;
Enrollment = currentEnrollment;
max_enrollment = max_ currentEnrollment;
}
public getCurrentEnrollment ()
{
return enrollment;
}
}

Can anyone help please?

What exactly are the problems you are having?

I haven't tried your code or anything, but I did just spot that your constructor has no capital 'C' on course. I'm not sure if that's just a typo here, but if it isn't and the code isn't running. That might be a reason.

you need the following two methods

public void addStudents(int moreStudents){
    enrollment += moreStudents;
}

public boolean overFull(){
    return enrollment > max_enrollment;
}
