The truncatedTo() method of an Instant class is used to get the value of this Instant in the specified unit. This method takes a parameter Unit, which is the Unit in which this Instant is to be truncated to. It returns a truncated immutable Instant with the value in the specified unit.
public Instant truncatedTo(TemporalUnit unit)
Parameter: This method takes a parameter unit which is the unit in which this Instant is to be truncated to. It should not be null.
Returns: This method returns an immutable truncated Instant with the value in the specified unit.
Exception: This method throws following Exceptions:
- DateTimeException: if the unit is invalid for truncation.
- UnsupportedTemporalTypeException: if the unit is not supported.
Below programs illustrate the Instant.truncatedTo() method:
Instant before truncate: 2018-12-30T09:24:54.630Z Instant after truncate: 2018-12-30T09:00:00Z
Instant before truncate: 2018-12-30T09:24:54.630Z Instant after truncate: 2018-12-30T00:00:00Z
Program 3: To show Exception:
Exception: java.time.temporal.UnsupportedTemporalTypeException: Unit is too large to be used for truncation
