Answer 1

java.time

Using java.time framework built into Java 8

int year = 2015;
int month = 12;
int day = 22;
LocalDate.of(year, month, day); //2015-12-22
LocalDate.parse("2015-12-22"); //2015-12-22
//with custom formatter 
DateTimeFormatter.ofPattern formatter = DateTimeFormatter.ofPattern("dd-MM-yyyy");
LocalDate.parse("22-12-2015", formatter); //2015-12-22

If you need also information about time(hour,minute,second) use some conversion from LocalDate to LocalDateTime

LocalDate.parse("2015-12-22").atStartOfDay() //2015-12-22T00:00
