Netbeans 12 on Windows, Console not outputting System.out.print

问题

Running the following simple program in Netbeans 12 and finding that the print statements won't display until after all data is entered - so there is no prompting before the input request. When using println, it works as expected.

    public static void main(String[] args) {
    Scanner in = new Scanner(System.in);
    
    System.out.print("Enter first name: ");
    String firstName = in.next();

    System.out.print("Enter last name: ");
    String lastName = in.next();
    
    System.out.print("Enter age: ");
    int age = in.nextInt();
    
    System.out.printf("%-16s%-16s%-16s%n", "First Name", "Last Name", "Age");
    System.out.printf("%-16s%-16s%-16s%n", firstName, lastName, age);
