how to retrieve day month and year from Timestamp(long format)

Question

I need to retrieve day year and month from a timestamp object as long numbers:

public long getTimeStampDay()     {              String iDate = new SimpleDateFormat("dd/MM/yyyy")         .format(new Date(born_date.getDate()));           .....                return day; //just the day      }  public long getTimeStampMonth()     {     String iDate = new SimpleDateFormat("dd/MM/yyyy")         .format(new Date(born_date.getDate()));           .....                return month; //just month      }  public long getTimeStampYear()     {     String iDate = new SimpleDateFormat("dd/MM/yyyy")         .format(new Date(born_date.getDate()));           .....                return year; //just year     } 

born_date is a timestamp object.

Is it possible to do that?

Thanks in advance.

Answer 1

long timestamp = bornDate.getTime(); Calendar cal = Calendar.getInstance(); cal.setTimeInMillis(timestamp); return cal.get(Calendar.YEAR); 

There are calendar fields for each property you need.

Alternatively you can use joda-time:

DateTime dateTime = new DateTime(bornDate.getDate()); return datetime.getYear(); 

Answer 2

A little refreshment of this well-accepted thread that is a bit outdated by now.

Back in the day, Java 8 introduced Date and Time API which makes extracting much cleaner.

Let's assume that bornDate is instance of LocalDateTime.

bornDate.getDayOfMonth(); // extracts day of month bornDate.getMonth();      // extracts month bornDate.getYear();       // extracts year
