public class TestDate {
public static void main(String[] args) {
// 2019-05-22
Calendar cal = Calendar.getInstance();
System.out.println(cal.get(Calendar.MONTH) + 1);
System.out.println(cal.get(Calendar.DAY_OF_MONTH));
System.out.println(cal.get(Calendar.WEEK_OF_MONTH));
System.out.println(cal.get(Calendar.DAY_OF_WEEK));
}
}
2019-05-22执行效果如下：5月，22日，第四周，第四周的第四天（周日为第一天）
