All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<LocalTime>, Temporal, TemporalAccessor, TemporalAdjuster
```
public final class LocalTime
extends java.lang.Object
implements Temporal, TemporalAdjuster, java.lang.Comparable<LocalTime>, java.io.Serializable
```
A time without 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.
It 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.
Specification for implementors

  - isSupported
```
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 and get 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_HOUR
    - 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.doIsSupported(TemporalAccessor) passing this as the argument. Whether the field is supported is determined by the field.
    Specified by:
    
    isSupported in interface TemporalAccessor
    
    Parameters:
    field - the field to check, null returns false
    
    Returns:
    true if the field is supported on this time, false if not
  - range
```
public ValueRange range(TemporalField field)
```
    Gets the range of valid values for the specified field.
    The range object expresses the minimum and maximum valid values for a field. This time is used to enhance the accuracy of the returned range. If it is not possible to return the range, 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 appropriate range instances. All other ChronoField instances will throw a DateTimeException.
    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.doRange(TemporalAccessor) passing this as the argument. Whether the range can be obtained is determined by the field.
    
    Specified by:
    
    range in interface TemporalAccessor
    
    Parameters:
    field - the field to query the range for, not null
    
    Returns:
    the range of valid values for the field, not null
    
    Throws:
    
    DateTimeException - if the range for the field cannot be obtained
  - get
```
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 for 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 a DateTimeException.
    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.doGet(TemporalAccessor) passing this as the argument. Whether the value can be obtained, and what the value represents, is determined by the field.
    
    Specified by:
    
    get in interface TemporalAccessor
    
    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
    
    java.lang.ArithmeticException - if numeric overflow occurs
  - getLong
```
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 for 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 a DateTimeException.
    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.doGet(TemporalAccessor) passing this as the argument. Whether the value can be obtained, and what the value represents, is determined by the field.
    
    Specified by:
    
    getLong in interface TemporalAccessor
    
    Parameters:
    field - the field to get, not null
    
    Returns:

  - with
```
public LocalTime with(TemporalAdjuster adjuster)
```
    Returns an adjusted copy of this time.
    This returns a new LocalTime, based on this one, with the time adjusted. The adjustment takes place using the specified adjuster strategy object. Read the documentation of the adjuster to understand what adjustment will be made.
    A simple adjuster might simply set the one of the fields, such as the hour field. A more complex adjuster might set the time to the last hour of the day.
    The result of this method is obtained by invoking the TemporalAdjuster.adjustInto(Temporal) method on the specified adjuster passing this as the argument.
    This instance is immutable and unaffected by this method call.
    
    Specified by:
    
    with in interface Temporal
    
    Parameters:
    adjuster - the adjuster to use, not null
    
    Returns:
    a LocalTime based on this with the adjustment made, not null
    
    Throws:
    
    DateTimeException - if the adjustment cannot be made
    
    java.lang.ArithmeticException - if numeric overflow occurs
  - with
```
public LocalTime with(TemporalField field,
             long newValue)
```
    Returns a copy of this time with the specified field set to a new value.
    This returns a new LocalTime, based on this one, with the value for the specified field changed. This can be used to change any supported field, such as the hour, minute or second. If it is not possible to set 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 adjustment is implemented here. The supported fields behave as follows:
    - NANO_OF_SECOND - Returns a LocalTime with the specified nano-of-second. The hour, minute and second will be unchanged.
    - NANO_OF_DAY - Returns a LocalTime with the specified nano-of-day. This completely replaces the time and is equivalent to ofNanoOfDay(long).
    - MICRO_OF_SECOND - Returns a LocalTime with the nano-of-second replaced by the specified micro-of-second multiplied by 1,000. The hour, minute and second will be unchanged.
    - MICRO_OF_DAY - Returns a LocalTime with the specified micro-of-day. This completely replaces the time and is equivalent to using ofNanoOfDay(long) with the micro-of-day multiplied by 1,000.
    - MILLI_OF_SECOND - Returns a LocalTime with the nano-of-second replaced by the specified milli-of-second multiplied by 1,000,000. The hour, minute and second will be unchanged.
    - MILLI_OF_DAY - Returns a LocalTime with the specified milli-of-day. This completely replaces the time and is equivalent to using ofNanoOfDay(long) with the milli-of-day multiplied by 1,000,000.
    - SECOND_OF_MINUTE - Returns a LocalTime with the specified second-of-minute. The hour, minute and nano-of-second will be unchanged.
    - SECOND_OF_DAY - Returns a LocalTime with the specified second-of-day. The nano-of-second will be unchanged.
    - MINUTE_OF_HOUR - Returns a LocalTime with the specified minute-of-hour. The hour, second-of-minute and nano-of-second will be unchanged.
    - MINUTE_OF_DAY - Returns a LocalTime with the specified minute-of-day. The second-of-minute and nano-of-second will be unchanged.
    - HOUR_OF_AMPM - Returns a LocalTime with the specified hour-of-am-pm. The AM/PM, minute-of-hour, second-of-minute and nano-of-second will be unchanged.
    - CLOCK_HOUR_OF_AMPM - Returns a LocalTime with the specified clock-hour-of-am-pm. The AM/PM, minute-of-hour, second-of-minute and nano-of-second will be unchanged.
    - HOUR_OF_DAY - Returns a LocalTime with the specified hour-of-day. The minute-of-hour, second-of-minute and nano-of-second will be unchanged.
    - CLOCK_HOUR_OF_DAY - Returns a LocalTime with the specified clock-hour-of-day. The minute-of-hour, second-of-minute and nano-of-second will be unchanged.
    - AMPM_OF_DAY - Returns a LocalTime with the specified AM/PM. The hour-of-am-pm, minute-of-hour, second-of-minute and nano-of-second will be unchanged.
    In all cases, if the new value is outside the valid range of values for the field then a DateTimeException will be thrown.
    All other ChronoField instances will throw a DateTimeException.
    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.doWith(Temporal, long) passing this as the argument. In this case, the field determines whether and how to adjust the instant.
    This instance is immutable and unaffected by this method call.

  - query
```
public <R> R query(TemporalQuery<R> query)
```
    Queries this time using the specified query.
    This queries this time using the specified query strategy object. The TemporalQuery object 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 passing this as the argument.
    
    Specified by:
    
    query in 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)

  - adjustInto
```
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.
    Specified by:
    
    adjustInto in 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
    
    java.lang.ArithmeticException - if numeric overflow occurs
  - periodUntil
```
public long periodUntil(Temporal endTime,
               TemporalUnit unit)
```
    Calculates the period between this time and another time in terms of the specified unit.
    This calculates the period between two times in terms of a single unit. The start and end points are this and the specified time. The result will be negative if the end is before the start. The Temporal passed to this method must be a LocalTime. For example, the period in hours between two times can be calculated using startTime.periodUntil(endTime, HOURS).
    The calculation returns a whole number, representing the number of complete units between the two times. For example, the period in hours between 11:30 and 13:29 will only be one hour as it is one minute short of two hours.
    This method operates in association with TemporalUnit.between(R, R). The result of this method is a long representing the amount of the specified unit. By contrast, the result of between is an object that can be used directly in addition/subtraction:
```
   long period = start.periodUntil(end, HOURS);   // this method
   dateTime.plus(HOURS.between(start, end));      // use in plus/minus
 
```
    The calculation is implemented in this method for ChronoUnit. The units NANOS, MICROS, MILLIS, SECONDS, MINUTES, HOURS and HALF_DAYS are supported. Other ChronoUnit values will throw an exception.
    If the unit is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.between(Temporal, Temporal) passing this as the first argument and the input temporal as the second argument.
    This instance is immutable and unaffected by this method call.
    Specified by:
    
    periodUntil in interface Temporal
    
    Parameters:
    endTime - the end time, which must be a LocalTime, not null
    unit - the unit to measure the period in, not null
    
    Returns:
    the amount of the period between this time and the end time
    
    Throws:
    
    DateTimeException - if the period cannot be calculated
    
    java.lang.ArithmeticException - if numeric overflow occurs
