9. //怎么让程序一直运行
10. Scanner scan = new Scanner(System.in);
11. while(scan.hasNext()) {
12. String in = scan.next().toString();
13. if(OPERATION_EXIT.equals(in.toUpperCase())
14. || OPERATION_EXIT.substring(0, 1).equals(in.toUpperCase())) {
15. System.out.println("您成功已退出！");
16. break;
17. }
18. System.out.println("您输入的值："+in);
19. }
