1:

Import java.util.*;
int y,m,d,h,mm;

Calendar C = calendar.getinstance ();

y = C.get (calendar.year); Years

m = C.get (calendar.month) + 1; Month

D = C.get (Calendar.day_of_month); Day

h = c.get (Calendar.hour); Time 12-hour system

H2 = C.get (calendar.hour_of_day);//24-hour system

MM = C.get (Calendar.minute); Score of

2:

Java.util.Date d = new Java.util.Date ();

Java.text.SimpleDateFormat Dformat = new Java.text.SimpleDateFormat ("Yyyy-mm-dd");

String datetime = Dformat.format (d); SYSTEM.OUT.PRINTLN (datetime);

3:

Import java.util.*; Import java.text.*;
Date now = new Date ();

DateFormat DefaultFormat = Dateformat.getdateinstance ();

DateFormat Shortformat = dateformat.getdateinstance (Dateformat.short);

DateFormat Mediumformat = dateformat.getdateinstance (Dateformat.medium);

DateFormat Longformat = dateformat.getdateinstance (Dateformat.long);

DateFormat Fullformat = dateformat.getdateinstance (dateformat.full);

String defaultdate = Defaultformat.format (now);

String shortdate = Shortformat.format (now);

String mediumdate = Mediumformat.format (now);

String longdate = Longformat.format (now);

String fulldate = Fullformat.format (now);

System.out.println ("(Default) Today:" + defaultdate);

System.out.println ("(short) Today:" + shortdate);

System.out.println ("(MEDIUM) Today:" + mediumdate);

System.out.println ("(LONG) Today:" + longdate); System.out.println ("(Full) Today:" + fulldate);

4.
If it is only a year or so, it can be intercepted with substring (). or with this.

String time=new SimpleDateFormat ("Yyyy-mm-dd"). Format (Calendar.getinstance (). GetTime);

5.

Date currenttime = new Date ();

SimpleDateFormat formatter = new SimpleDateFormat ("Yyyy-mm-dd");

String datestring = Formatter.format (currenttime);

The datastring format is the 2007-03-08 type.
