A LocalTime object can be obtained using the seconds of the day with the ofSecondOfDay() method in the LocalTime class in Java. This method requires a single parameter i.e. the seconds of the day and it returns the LocalTime object for the seconds of the day.A program that demonstrates this is given as followsExample Live Demoimport java.time.*; public class Demo {    public static void main(String[] args) {       long seconds = 18930;       System.out.println("The seconds of the day: " + seconds);       System.out.println("The LocalTime is: " + LocalTime.ofSecondOfDay(seconds));    } }outputThe seconds of the ...

The rangeClosed() class in the IntStream class returns a sequential ordered IntStream from startInclusive to endInclusive by an incremental step of 1. This includes both the startInclusive and endInclusive values.The syntax is as followsstatic IntStream rangeClosed(int startInclusive, int endInclusive)Here, startInclusive is the value including the first value and endInclusive is the value indicating the last value. To work with the IntStream class in Java, import the following packageimport java.util.stream.IntStream;The following is an example to implement IntStream rangeClosed() method in JavaExample Live Demoimport java.util.stream.IntStream; public class Demo { public static void main(String[] args) { ...

The mapToLong() method of the DoubleStream class returns a LongStream consisting of the results of applying the given function to the elements of this stream.The syntax is as followsLongStream mapToLong(DoubleToLongFunction mapper)Here, the parameter mapper is a stateless function to apply to each element. The DoubleToLongFunction here is a function that accepts a double-valued argument and produces a long-valued result.To use the DoubleStream class in Java, import the following packageimport java.util.stream.DoubleStream;Create a DoubleStream and add some elementsDoubleStream doubleStream = DoubleStream.of(30.5, 45.8, 89.3);Now, use the LongStream and set a condition for the stream elementsLongStream longStream = doubleStream.mapToLong(a -> (long)a); The following is ...

The hash code value of the LocalTime can be obtained using the hashCode() method in the LocalTime class in Java. This method requires no parameters and it returns the hash code value of the LocalTime.A program that demonstrates this is given as followsExample Live Demoimport java.time.*; public class Demo { public static void main(String[] args) {    LocalTime lt = LocalTime.parse("23:15:30");       System.out.println("The LocalTime is: " + lt);       System.out.println("The hash code is: " + lt.hashCode());    } }outputThe LocalTime is: 23:15:30 The hash code is: -387418074Now let us understand the above program.First the LocalTime is displayed. ...

The averagingLong() method of the Collectors class returns a Collector that produces the arithmetic mean of a long-valued function applied to the input elements.The syntax is as followsstatic Collector averagingLong(ToLongFunction

The noneMatch() method of the DoubleStream class returns true if none of the elements of this stream match the provided predicate.The syntax is as followsboolean noneMatch(DoublePredicate predicate)Here, predicate is a stateless predicate to apply to elements of this stream. To use the DoubleStream class in Java, import the following packageimport java.util.stream.DoubleStream;Create DoubleStream and add some elements to the streamDoubleStream doubleStream = DoubleStream.of(15.8, 28.7, 35.7, 48.1, 78.9);Now, TRUE is returned if none of the element match the conditionboolean res = doubleStream.noneMatch(num -> num > 90); The following is an example to implement DoubleStream noneMatch() method in JavaExample Live Demoimport java.util.*; import java.util.stream.DoubleStream; ...
