In Java we can use java.util.Date package or java.util.Calendar to work with Date and time. Let us see some simple examples.

1) java.util.Date

Get current Date

Java

Date date = new Date(); System.out.println(date);

2

Date date = new Date();
System.out.println(date);

Output

Sat May 14 16:21:23 IST 2016

Sat May 14 16:21:23 IST 2016

Convert String to date

SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/MM/yyyy");
String strDate = "12/05/2016";
Date date = simpleDateFormat.parse(strDate);
System.out.println(date);

SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/MM/yyyy");

String strDate = "12/05/2016";

Date date = simpleDateFormat.parse(strDate);

System.out.println(date);

Output

Thu May 12 00:00:00 IST 2016

1	Thu May 12 00:00:00 IST 2016

Date formatting using date formatter

Java

Date date = new Date(); SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/MM/yyyy"); System.out.println(simpleDateFormat.format(date));

2
3

Date date = new Date();
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/MM/yyyy");
System.out.println(simpleDateFormat.format(date));

Output

14/05/2016

14/05/2016
Get current date time

Java

SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss"); Date date = new Date(); System.out.println(simpleDateFormat.format(date));

1
2
3

SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss");
Date date = new Date();
System.out.println(simpleDateFormat.format(date));

Output

14/05/2016 04:42:16

14/05/2016 04:42:16

2) java.util.Calendar

Get current Date

Java

Calendar calendar = Calendar.getInstance(); Date date = calendar.getTime(); System.out.println(date);

1
2
3

Calendar calendar = Calendar.getInstance();
Date date = calendar.getTime();
System.out.println(date);

Output

Sat May 14 22:21:06 IST 2016

Sat May 14 22:21:06 IST 2016

Convert String to Calendar

SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/MM/yyyy");
String strDate = "12/05/2016";
Date date = simpleDateFormat.parse(strDate);
Calendar calendar = Calendar.getInstance();
calendar.setTime(date);
System.out.println(date);

SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/MM/yyyy");

String strDate = "12/05/2016";

Date date = simpleDateFormat.parse(strDate);

Calendar calendar = Calendar.getInstance();

calendar.setTime(date);

System.out.println(date);

Output

Thu May 12 00:00:00 IST 2016

1	Thu May 12 00:00:00 IST 2016

Get current date time

SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss");
Calendar calendar = Calendar.getInstance();
Date date = calendar.getTime();
System.out.println(simpleDateFormat.format(date));

SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss");

Calendar calendar = Calendar.getInstance();

Date date = calendar.getTime();

System.out.println(simpleDateFormat.format(date));

Output

14/05/2016 10:26:39

1	14/05/2016 10:26:39
