How to combine date and time into a single object?

deepak rawat :

my dao page is receiving date and time from two different field now i want know how to merge these both date and time in a single object so that i calculate time difference and total time. I have this code to merge but it is not working what am i doing wrong in this code please help.

    Date d = new SimpleDateFormat("yyyy-MM-dd").parse("2013-01-02");
    Date t = new SimpleDateFormat("hh:mm:ss").parse("04:05:06");
    LocalDate datePart = new LocalDate(d);
    LocalTime timePart = new LocalTime(t);
    LocalDateTime dateTime = datePart.toLocalDateTime(timePart);
    System.out.println(dateTime);

Sweeper :

You just need to use the correct methods, instead of calling constructors. Use parse to create local date and local time objects, then pass the two objects to the of method of LocalDateTime:

    LocalDate datePart = LocalDate.parse("2013-01-02");
    LocalTime timePart = LocalTime.parse("04:05:06");
    LocalDateTime dt = LocalDateTime.of(datePart, timePart);

EDIT

Apparently, you need to combine two Date objects instead of 2 strings. I guess you can first convert the two dates to strings using SimpleDateFormat. Then use the methods shown above.

String startingDate = new SimpleDateFormat("yyyy-MM-dd").format(startDate);
String startingTime = new SimpleDateFormat("hh:mm:ss").format(startTime);
