Answer to Question #58415 in Java | JSP | JSF for Lekorius Wallace

Question #58415
Design a Java program that asks for the number of students registered in a course. The user should be prompted to enter the number of students enrolled in a course. If the number of students is greater than 0, use a counter-controlled while loop to prompt the user to enter the names of the students registered for the class. Create an output file that contains the names of the students in the class. Display a message to the user when the program is complete.
