What is wrong with the code below :

Scanner scanner = new Scanner(System.in); int option = scanner.nextInt(); switch (option) { case 1: System.out.println("1 -> New"); break; case 2: System.out.println("2 -> Edit"); break; case 3: System.out.println("3 -> Delete"); break; case 4: System.out.println("4 -> View"); break; case 5: System.out.println("5 -> Quit"); default: System.out.println("Unknown command"); }
