public static void main(String[] args) throws java.text.ParseException {
System.out.println("输入天数：");
Scanner scan = new Scanner(System.in);
int day = scan.nextInt();
String createDate = "2000-01-01";
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-mm-dd");
try {
Date date = sdf.parse(createDate);
Calendar cl = Calendar.getInstance();
cl.setTime(date);
// cl.set(Calendar.DATE, day);
cl.add(Calendar.DATE, day);
String temp = "";
temp = sdf.format(cl.getTime());
System.out.println(temp);
} catch (ParseException e) {
// TODO Auto-generated catch block
