The nanosecond of second for a particular LocalTime can be obtained using the getNano() method in the LocalTime class in Java. This method requires no parameters and it returns the nanosecond of second in the range of 0 to 999, 999, 999.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("23:15:30.53");       System.out.println("The LocalTime is: " + lt);       System.out.println("The nanosecond is: " + lt.getNano());    } }outputThe LocalTime is: 23:15:30.530 The nanosecond is: 530000000Now let us ...

The drainTo() method of the ArrayBlockingQueue class removes all available elements from this queue and adds them to the given collection. It returns the number of elements transferred.The syntax is as followsint drainTo(Collection

Collections reverse order class is a reverse order method, which is encoded in the collections class. It is present in the java.util package. It returns a comparator as a result, which is a predefined comparator in nature. By using this comparator package, we can rearrange the collections of a particular data set in a reverse manner. The Collectors toSet() is a collector class, which itself returns a collector and accumulates those particular elements as an input into a new set. toSet() is an unordered collector class which is not accountable to preserve the order of the encounter of some input ...

The parallel() method of the DoubleStream class returns an equivalent stream which is parallel.The syntax is as followsDoubleStream parallel()To use the DoubleStream class in Java, import the following packageimport java.util.stream.DoubleStream;The following is an example to implement DoubleStream parallel() method in JavaExample Live Demoimport java.util.*; import java.util.stream.DoubleStream; public class Demo {    public static void main(String[] args) { DoubleStream doubleStream = DoubleStream.of(35.8, 14.9, 23.3, 67.8, 89.4, 45.6); System.out.println("Parallel DoubleStream = "); doubleStream.parallel().forEach(System.out::println); } }OutputParallel DoubleStream = 67.8 14.9 23.3 89.4 45.6 35.8

A LabelValue class is a Tuple of 2 elements with label as the first position, whereas value as the second. It is in the JavaTuples library. The LabelValue Tuple class is Typesafe, Immutable, Iterable, Serializable, etc.The following is the declaration of the LabelValue class;public final class LabelValue extends Tuple implements IValueLabel, IValueValueLet us first see what we need to work with JavaTuples. To work with LabelValue class in JavaTuples, you need to import the following packageimport org.javatuples.LabelValue;Note: Download JavaTuples Jar library to run JavaTuples program. If you are using Eclipse IDE, then Right Click Project -> Properties -> Java Build Path ... Read More

The setAtX() method is used to set a new value in the Decade Tuple. Here, X is the index wherein you want to set the value. For example, setAt5() sets the value at index 5. The value to be included is to be set as the value in the parameter, likesetAt5(“Katie”);Let us first see what we need to work with JavaTuples. To work with Decade class in JavaTuples, you need to import the following packageimport org.javatuples.Decade;Note: Download JavaTuples Jar library to run JavaTuples program. If you are using Eclipse IDE, then Right Click Project -> Properties -> Java Build Path ... Read More
