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2019227New 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
