skipping a step

when i run the program it will not allow me to enter 'yes' or 'no' in response. it runs the "Please enter...." line, gives a space, and moves on to the next section of code in the program. (not shown)

edit: I decided to just put the whole method on here because when i tested the piece from before it worked fine.

public static void userInterface()
{

Scanner scan = new Scanner(System.in);

System.out.println("Please enter 'Avatar', 'The Blind Side', or 'Up'.\n");
String movie = scan.nextLine();
if(!movie.equals("Avatar") ^ !movie.equals("The Blind Side") ^ !movie.equals("Up"))
{

System.out.println("\nInvalid input");
System.exit(1);

}

System.out.println("\n");

System.out.println("Please enter the month you wish to see the movie in as an integer.");
System.out.println("('3' for March, '4' for April, '5' for May)\n");
int month = scan.nextInt();
if(month != 3 ^ month != 4 ^ month != 5)
{

System.out.println("\nInvalid input");
System.exit(1);

}

System.out.println("\n");

System.out.println("Please enter the date you wish to view the movie on.\n");
int date = scan.nextInt();
if(!isValidDate(month, date))
{

System.out.println("\nInvalid input");
System.exit(1);

}

System.out.println("\n");

System.out.println("Please enter 'yes' or 'no' if you want to watch the matinee or not.\n");
String matineeOrNot = scan.nextLine();

boolean isMatinee;

if(matineeOrNot.equals("yes"))
{

isMatinee = true;

}
else
{

isMatinee = false;

}

if(!matineeOrNot.equals("yes") && !matineeOrNot.equals("no"))
{

System.out.println("\nInvalid input");
System.exit(1);

}

System.out.println("\n");

System.out.println("Please enter the number of adult tickets you want.\n");
System.out.println("('0' if none)");
int adultTickets = scan.nextInt();
if(adultTickets < 0)
{

System.out.println("\nInvalid input");
System.exit(1);

}

System.out.println("\n");

System.out.println("Please enter the number of student tickets you want.");
System.out.println("('0' if none)\n");
int studentTickets = scan.nextInt();
if(studentTickets < 0)
{

System.out.println("\nInvalid input");
System.exit(1);

}

System.out.println("\n");

System.out.println("Your tickets cost $" + getCost(movie,month,date,isMatinee,adultTickets,studentTickets));

}

Try to use just next() to read the String.

would you mind elaborating? i just started java a few weeks ago.

Sure - in your current code you're doing:

Instead, try:

I always have problems with the nextLine method reading and behaving differently than I want.

that worked, thank you very much.
