Question

I’m trying to have the option of reading a string with multiple words, ie. Los Angeles or New York City. Using scanner.next() for “Departure” and “Arrival” would only read the first one if there were two words and split them between variables. nextLine() has not been much luck either. Here’s my code:

            System.out.print("\nEnter flight number: ");
            int flightNumber = Integer.valueOf(scanner.nextLine());
            System.out.print("\nEnter departing city: ");
            String departingCity = scanner.nextLine();
            System.out.print("\nEnter arrival city: ");
            String arrivalCity = scanner.nextLine();

I know it’s something simple but I haven’t figured it out.

Here’s the input/output w/ the code above:

Enter flight number: 29

Enter departing city: (immediately it skips to the next line)

Enter arrival city:

—- What I’m really going for —-

Enter flight number: 29

Enter departing City: Los Angeles (be able to type multiple words without it skipping the next input)

Enter arrival city: Kansas City

Your problem is that next() does not read the carriage return and it gets automatically read by your next next() or nextLine(). Use nextLine() all time and convert input to integer:

public static void main(String[] args) throws Exception {
    Scanner scanner = new Scanner(System.in);
    System.out.print("\nEnter flight number: ");
    int flightNumber = Integer.valueOf(scanner.nextLine());
    System.out.print("\nEnter departing city: ");
    String departingCity = scanner.nextLine();
    System.out.print("\nEnter arrival city: ");
    String arrivalCity = scanner.nextLine();

}
