/////////my subscriber class////////////////////////////////////////////
class Subscriber{
	String movie;
	String Subscriber;
	String movieType;

	public Subscriber(String movie, String subscriber, String movieType) {
		super();
		this.movie = movie;
		Subscriber = subscriber;
		this.movieType = movieType;

	}

	@Override
	public String toString() {
		return "Subscriber [Subscriber=" + Subscriber + ", movie=" + movie
				+ ", movieType=" + movieType + "]";
	}
	
	
	
	
}

so the problem is due to lack of visibility. i want to create types of subscribers (let the user type the info) and send those type to an arraylist called "sub". then i want to print that arraylist.. problem is it says "the code is not reachable"
at the line indicated after the while loop

This is because your while loop says while (true), and the only place where you break out of the loop you "return" from main. Either change the condition of the loop using your stop variable, or change the return statement to a break statement, which will just break out of the loop but won't end the function.
