java.util.Calendar无法正确设置Month

Question

The issue is pretty simple. What I want is to create a Calendar and set it with this attributes: Day: 17 Month: 10 (october) Year: 1989

But the calendar is not setting the MONTH properly.

This is the code:

Calendar fecha = new GregorianCalendar();
fecha.set(Calendar.DAY_OF_YEAR, 17);
fecha.set(Calendar.MONTH, Calendar.OCTOBER);
System.out.println(new SimpleDateFormat("dd/MM/yyyy").format(fecha.getTime()));

And what I'm getting: 17/01/2013 ------------>The month is not October

What's wrong with this? Thanks in advance!

Answer 1

如果要设置月份和年份，那么在设置日期时，请使用DAY_OF_MONTH而不是DAY_OF_YEAR 。

Answer 2

fecha.set(Calendar.DAY_OF_YEAR, 17);

belongs to JANUARY

You need to set Calendar.DATE

Answer 3

Replace:

Calendar fecha = new GregorianCalendar();
fecha.set(Calendar.DAY_OF_MONTH, 17);
fecha.set(Calendar.MONTH, Calendar.OCTOBER);
System.out.println(new SimpleDateFormat("dd/MM/yyyy").format(fecha.getTime()));
