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));
}
