 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.
 This is a value-based
 class; programmers should treat instances that are
 equal as interchangeable and should not
 use instances for synchronization, or unpredictable behavior may
 occur. For example, in a future release, synchronization may fail.
 The equals method should be used for comparisons.
- Implementation Requirements:
- This class is immutable and thread-safe.

- 
queryQueries this time using the specified query.This queries this time using the specified query strategy object. The TemporalQueryobject defines the logic to be used to obtain the result. Read the documentation of the query to understand what the result of this method will be.The result of this method is obtained by invoking the TemporalQuery.queryFrom(TemporalAccessor)method on the specified query passingthisas the argument.- Specified by:
- queryin interface- TemporalAccessor
- Type Parameters:
- R- the type of the result
- Parameters:
- query- the query to invoke, not null
- Returns:
- the query result, null may be returned (defined by the query)
- Throws:
- DateTimeException- if unable to query (defined by the query)
- ArithmeticException- if numeric overflow occurs (defined by the query)
 
- 
adjustIntoAdjusts 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)passingChronoField.NANO_OF_DAYas 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. - Specified by:
- adjustIntoin interface- TemporalAdjuster
- 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
 
- 
untilCalculates the amount of time until another time in terms of the specified unit.This calculates the amount of time between two LocalTimeobjects in terms of a singleTemporalUnit. The start and end points arethisand the specified time. The result will be negative if the end is before the start. TheTemporalpassed to this method is converted to aLocalTimeusingfrom(TemporalAccessor). For example, the amount in hours between two times can be calculated usingstartTime.until(endTime, HOURS).The calculation returns a whole number, representing the number of complete units between the two times. For example, the amount in hours between 11:30 and 13:29 will only be one hour as it is one minute short of two hours. There are two equivalent ways of using this method. The first is to invoke this method. The second is to use TemporalUnit.between(Temporal, Temporal):// these two lines are equivalent amount = start.until(end, MINUTES); amount = MINUTES.between(start, end); The choice should be made based on which makes the code more readable.The calculation is implemented in this method for ChronoUnit. The unitsNANOS,MICROS,MILLIS,SECONDS,MINUTES,HOURSandHALF_DAYSare supported. OtherChronoUnitvalues will throw an exception.If the unit is not a ChronoUnit, then the result of this method is obtained by invokingTemporalUnit.between(Temporal, Temporal)passingthisas the first argument and the converted input temporal as the second argument.This instance is immutable and unaffected by this method call. - Specified by:
- untilin interface- Temporal
- Parameters:
- endExclusive- the end time, exclusive, which is converted to a- LocalTime, not null
- unit- the unit to measure the amount in, not null
- Returns:
- the amount of time between this time and the end time
- Throws:
- DateTimeException- if the amount cannot be calculated, or the end temporal cannot be converted to a- LocalTime
- UnsupportedTemporalTypeException- if the unit is not supported
- ArithmeticException- if numeric overflow occurs
 
- 
formatFormats 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

- 
toEpochSecondConverts thisLocalTimeto the number of seconds since the epoch of 1970-01-01T00:00:00Z.This combines this local time with the specified date and offset to calculate the epoch-second value, which is the number of elapsed seconds from 1970-01-01T00:00:00Z. Instants on the time-line after the epoch are positive, earlier are negative. - Parameters:
- date- the local date, not null

- the number of seconds since the epoch of 1970-01-01T00:00:00Z, may be negative
- Since:
- 9

compareToCompares 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.- Specified by:
- compareToin interface- Comparable<LocalTime>
- Parameters:
- other- the other time to compare to, not null
- Returns:
- the comparator value, that is less than zero if this is before other, zero if they are equal, or greater than zero if this is afterother
- See Also:
 
- 
isAfterChecks if this time is after the specified time.The comparison is based on the time-line position of the time within a day. - Parameters:
- other- the other time to compare to, not null
- Returns:
- true if this is after the specified time
 
- 
isBeforeChecks if this time is before the specified time.The comparison is based on the time-line position of the time within a day. - Parameters:
- other- the other time to compare to, not null
- Returns:
- true if this point is before the specified time
 
- 
equalsChecks 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 LocalTimeare compared, other types return false. To compare the date of twoTemporalAccessorinstances, useChronoField.NANO_OF_DAYas a comparator.
