The truncatedTo() method of a LocalTime class is used to get the value of this LocalTime in the specified unit. This method takes a parameter Unit, which is the unit in which this LocalTime is to be truncated to. It returns a truncated immutable LocalTime with the value in the specified unit.
Syntax:
public LocalTime truncatedTo(TemporalUnit unit)
Parameters: This method accepts a single parameter unit which represents the unit to truncate to, It should not be null.
Return value: This method returns a immutable truncated LocalTime based on this time with the time truncated, not null.
Exception: This method throws following two exception:
- DateTimeException: if unable to truncate.
- UnsupportedTemporalTypeException: if the unit is not supported
Below programs illustrate the truncatedTo() method:
Program 1:
// Java program to demonstrate// LocalTime.truncatedTo() method  import java.time.*;import java.time.temporal.ChronoUnit;  public class GFG {    public static void main(String[] args)    {          // create a LocalTime object        LocalTime time            = LocalTime.parse("21:45:36.13");          // print instance        System.out.println("LocalTime before"                           + " truncate: "                           + time);          // truncate to ChronoUnit.MINUTES        // means unit smaller than Minute        // will be Zero        LocalTime returnvalue            = time.truncatedTo(ChronoUnit.MINUTES);          // print result        System.out.println("LocalTime after "                           + " truncate: "                           + returnvalue);    }} |
LocalTime before truncate: 21:45:36.130 LocalTime after truncate: 21:45
Program 2:
// Java program to demonstrate// LocalTime.truncatedTo() method  import java.time.*;import java.time.temporal.ChronoUnit;  public class GFG {    public static void main(String[] args)    {          // create a LocalTime object        LocalTime time            = LocalTime.parse("01:21:30.13");          // print instance        System.out.println("LocalTime before"                           + " truncate: "                           + time);          // truncate to ChronoUnit.HOURS        // means unit smaller than Hour        // will be Zero        LocalTime returnvalue            = time.truncatedTo(ChronoUnit.HOURS);          // print result        System.out.println("LocalTime after "                           + " truncate: "                           + returnvalue);    }} |
LocalTime before truncate: 01:21:30.130 LocalTime after truncate: 01:00
