How to transform a time value into YYYY-MM-DD format in Java?

Question

How can I transform a time value into YYYY-MM-DD format in Java?

long lastmodified = file.lastModified();
String lasmod =  /*TODO: Transform it to this format YYYY-MM-DD*/

Answer 1

Something like:

Date lm = new Date(lastmodified);
String lasmod = new SimpleDateFormat("yyyy-MM-dd").format(lm);

See the javadoc for SimpleDateFormat.

Answer 2

final Date modDate = new Date(lastmodified);
final SimpleDateFormat f = new SimpleDateFormat("yyyy-MM-dd");
final String lasmod = f.format(modDate);
