Calendar Constructor Java toString

Question

What I\'m trying to do is pass a date into the Calendar so that it will format the date ready for use with another constructor. So that i can make use of it later using the func

Answer 1

LocalDate

Apparently you want a date-only value without a day-of-time. For that use the LocalDate class rather than Calendar. The Calendar class was for a date plus a time-of-day. Furthermore, Calendar is now legacy, supplanted by the java.time classes after having proven to be troublesome, confusing, and flawed.

Simply pass the desired year, month, and day-of-month to a factory method. The month is sanely numbered 1-12 for January-December unlike Calendar.

LocalDate ld = LocalDate.of( 2012 , 10 , 20 );

Or, pass a constant for month.

LocalDate ld = LocalDate.of( 2012 , Month.OCTOBER , 20 );

The java.time classes tend to use static factory methods rather than constructors with new.

Strings

To generate a string in standard ISO 8601 format, call toString

String output = ld.toString() ;

2012-10-20

For other formats, search Stack Overflow for DateTimeFormatter. For example:

DateTimeFormatter f = DateTimeFormatter.ofPattern( "dd/MM/uuuu" );
String output = ld.format( f );
