The following example demonstrates how to use the Calendar class to output the year, month, etc.:
/* author by w3cschool.cc 文件名:Main.java */import java.util.Calendar;public class Main { public static void main(String[] args) { Calendar cal = Calendar.getInstance(); int day = cal.get(Calendar.DATE); int month = cal.get(Calendar.MONTH) + 1; int year = cal.get(Calendar.YEAR); int dow = cal.get(Calendar.DAY_OF_WEEK); int dom = cal.get(Calendar.DAY_OF_MONTH); int doy = cal.get(Calendar.DAY_OF_YEAR); System.out.println("当期时间: " + cal.getTime()); System.out.println("日期: " + day); System.out.println("月份: " + month); System.out.println("年份: " + year); System.out.println("一周的第几天: " + dow); // 星期日为一周的第一天输出为 1,星期一输出为 2,以此类推 System.out.println("一月中的第几天: " + dom); System.out.println("一年的第几天: " + doy); }}
The output result of running the above code is:
当期时间: Fri Mar 27 21:44:15 CST 2015 日期: 27 月份: 3 年份: 2015 一周的第几天: 6 一月中的第几天: 27 一年的第几天: 86
