LocalTime

public final class LocalTime extends Object
implements Temporal TemporalAdjuster Comparable<LocalTime> Serializable

A time without a time-zone in the ISO-8601 calendar system, such as 10:15:30.

LocalTime is an immutable date-time object that represents a time, often viewed as hour-minute-second. Time is represented to nanosecond precision. For example, the value "13:45.30.123456789" can be stored in a LocalTime.

This class does not store or represent a date or time-zone. Instead, it is a description of the local time as seen on a wall clock. It cannot represent an instant on the time-line without additional information such as an offset or time-zone.

The ISO-8601 calendar system is the modern civil calendar system used today in most of the world. This API assumes that all calendar systems use the same representation, this class, for time-of-day.

Public Methods

public Temporal adjustInto (Temporal temporal)

Adjusts the specified temporal object to have the same time as this object.

This returns a temporal object of the same observable type as the input with the time changed to be the same as this.

The adjustment is equivalent to using Temporal.with(TemporalField, long) passing ChronoField.NANO_OF_DAY as the field.

In most cases, it is clearer to reverse the calling pattern by using Temporal.with(TemporalAdjuster):

   // these two lines are equivalent, but the second approach is recommended
   temporal = thisLocalTime.adjustInto(temporal);
   temporal = temporal.with(thisLocalTime);

This instance is immutable and unaffected by this method call.

Parameters

temporal	the target object to be adjusted, not null

Returns

the adjusted object, not null

Throws

DateTimeException	if unable to make the adjustment
ArithmeticException	if numeric overflow occurs

public LocalDateTime atDate (LocalDate date)

Combines this time with a date to create a LocalDateTime.

This returns a LocalDateTime formed from this time at the specified date. All possible combinations of date and time are valid.

Parameters

date	the date to combine with, not null

Returns

the local date-time formed from this time and the specified date, not null

public OffsetTime atOffset (ZoneOffset offset)

Combines this time with an offset to create an OffsetTime.

This returns an OffsetTime formed from this time at the specified offset. All possible combinations of time and offset are valid.

Parameters

offset	the offset to combine with, not null

Returns

the offset time formed from this time and the specified offset, not null

public int compareTo (LocalTime other)

Compares this time to another time.

The comparison is based on the time-line position of the local times within a day. It is "consistent with equals", as defined by Comparable.

Parameters

other	the other time to compare to, not null

Returns

the comparator value, negative if less, positive if greater

Throws

NullPointerException	if `other` is null

public boolean equals (Object obj)

Checks if this time is equal to another time.

The comparison is based on the time-line position of the time within a day.

Only objects of type LocalTime are compared, other types return false. To compare the date of two TemporalAccessor instances, use ChronoField.NANO_OF_DAY as a comparator.

Parameters

obj	the object to check, null returns false

Returns

true if this is equal to the other time

public String format (DateTimeFormatter formatter)

Formats this time using the specified formatter.

This time will be passed to the formatter to produce a string.

Parameters

formatter	the formatter to use, not null

Returns

the formatted time string, not null

Throws

DateTimeException	if an error occurs during printing

public static LocalTime from (TemporalAccessor temporal)

Obtains an instance of LocalTime from a temporal object.

This obtains a local time based on the specified temporal. A TemporalAccessor represents an arbitrary set of date and time information, which this factory converts to an instance of LocalTime.

The conversion uses the TemporalQueries.localTime() query, which relies on extracting the NANO_OF_DAY field.

This method matches the signature of the functional interface TemporalQuery allowing it to be used as a query via method reference, LocalTime::from.

Parameters

temporal	the temporal object to convert, not null

Returns

the local time, not null

Throws

DateTimeException	if unable to convert to a `LocalTime`

public int get (TemporalField field)

Gets the value of the specified field from this time as an int.

This queries this time for the value of the specified field. The returned value will always be within the valid range of values for the field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the query is implemented here. The supported fields will return valid values based on this time, except NANO_OF_DAY and MICRO_OF_DAY which are too large to fit in an int and throw a DateTimeException. All other ChronoField instances will throw an UnsupportedTemporalTypeException.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.getFrom(TemporalAccessor) passing this as the argument. Whether the value can be obtained, and what the value represents, is determined by the field.

Parameters

field	the field to get, not null

Returns

the value for the field

Throws

DateTimeException	if a value for the field cannot be obtained or the value is outside the range of valid values for the field
UnsupportedTemporalTypeException	if the field is not supported or the range of values exceeds an `int`
ArithmeticException	if numeric overflow occurs

public int getHour ()

Gets the hour-of-day field.

Returns

the hour-of-day, from 0 to 23

public long getLong (TemporalField field)

Gets the value of the specified field from this time as a long.

This queries this time for the value of the specified field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the query is implemented here. The supported fields will return valid values based on this time. All other ChronoField instances will throw an UnsupportedTemporalTypeException.

Parameters

field	the field to get, not null

Returns

the value for the field

Throws

DateTimeException	if a value for the field cannot be obtained
UnsupportedTemporalTypeException	if the field is not supported
ArithmeticException	if numeric overflow occurs

Parameters

other	the other time to compare to, not null

Returns

true if this point is before the specified time

Throws

NullPointerException	if `other` is null

public boolean isSupported (TemporalUnit unit)

Checks if the specified unit is supported.

This checks if the specified unit can be added to, or subtracted from, this time. If false, then calling the plus(long, TemporalUnit) and minus methods will throw an exception.

If the unit is a ChronoUnit then the query is implemented here. The supported units are:

NANOS
MICROS
MILLIS
SECONDS
MINUTES
HOURS
HALF_DAYS

All other ChronoUnit instances will return false.

If the unit is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.isSupportedBy(Temporal) passing this as the argument. Whether the unit is supported is determined by the unit.

Parameters

unit	the unit to check, null returns false

Returns

true if the unit can be added/subtracted, false if not

public boolean isSupported (TemporalField field)

Checks if the specified field is supported.

This checks if this time can be queried for the specified field. If false, then calling the range, get and with(TemporalField, long) methods will throw an exception.

If the field is a ChronoField then the query is implemented here. The supported fields are:

NANO_OF_SECOND
NANO_OF_DAY
MICRO_OF_SECOND
MICRO_OF_DAY
MILLI_OF_SECOND
MILLI_OF_DAY
SECOND_OF_MINUTE
SECOND_OF_DAY

MINUTE_OF_DAY
HOUR_OF_AMPM
CLOCK_HOUR_OF_AMPM
HOUR_OF_DAY
CLOCK_HOUR_OF_DAY
AMPM_OF_DAY

All other ChronoField instances will return false.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.isSupportedBy(TemporalAccessor) passing this as the argument. Whether the field is supported is determined by the field.

Parameters

field	the field to check, null returns false

Returns

true if the field is supported on this time, false if not

public LocalTime minus (TemporalAmount amountToSubtract)

Returns a copy of this time with the specified amount subtracted.

This returns a LocalTime, based on this one, with the specified amount subtracted. The amount is typically Duration but may be any other type implementing the TemporalAmount interface.

The calculation is delegated to the amount object by calling TemporalAmount.subtractFrom(Temporal). The amount implementation is free to implement the subtraction in any way it wishes, however it typically calls back to minus(long, TemporalUnit). Consult the documentation of the amount implementation to determine if it can be successfully subtracted.

This instance is immutable and unaffected by this method call.

Parameters

amountToSubtract	the amount to subtract, not null

Returns

a LocalTime based on this time with the subtraction made, not null

Throws

DateTimeException	if the subtraction cannot be made
ArithmeticException	if numeric overflow occurs
