SimpleDateFormat.格式返回错误的日期

Question

我有这个代码，我想知道为什么它返回正确的日期

Festival f= (Festival) festival.get(0);

Date d=f.getSDate();

System.out.println(d.getYear());

System.out.println(d.getMonth());

System.out.println(d.getDate());

SimpleDateFormat df = new SimpleDateFormat("dd/MM/yyyy"); // define your format.

String formattedDate = df.format(d);

System.out.println("New Date To Show::"+formattedDate);

输出是这个

2019

2

27

New Date To Show::27/03/3919

Answer 1

尝试使用这个：   Date date=new Date();    // you can assign your return from the function here    LocalDate localDate = date.toInstant().atZone(ZoneId.systemDefault()).toLocalDate();    System.out.println(localDate.getMonthValue());    System.out.println(localDate.getDayOfMonth());    System.out.println(localDate.getYear());    SimpleDateFormat df = new SimpleDateFormat("dd/MM/yyyy");    String formattedDate = df.format(date);    System.out.println("New Date To Show::"+formattedDate);

Answer 2

这是因为月份（d.getMonth（））从零开始，而2实际上是3
