The builder() method of the DoubleStream class returns a builder for a DoubleStream.The syntax is as follows −static DoubleStream.Builder builder()To use the DoubleStream class in Java, import the following package −import java.util.stream.DoubleStream;The following is an example to implement DoubleStream builder() method in Java −Example Live Demoimport java.util.stream.Stream; import java.util.stream.DoubleStream; public class Demo {    public static void main(String[] args) {       DoubleStream doubleStream = DoubleStream.builder().add(15.9).build();       doubleStream.forEach(System.out::println);    } }Output15.9

The contains() method of the ArrayBlockingQueue class is used to search for an element in the queue. If the element exist in the queue, TRUE is returned.The syntax is as follows −boolean contains(Object ob)Here, ob is the element to be searched.To work with ArrayBlockingQueue class, you need to import the following package −import java.util.concurrent.ArrayBlockingQueue;The following is an example to implement contains() method of Java ArrayBlockingQueue class −Example Live Demoimport java.util.concurrent.ArrayBlockingQueue; public class Demo {    public static void main(String[] args) throws InterruptedException {       ArrayBlockingQueue q = new ArrayBlockingQueue(10);       q.add(200);       q.add(310);   ...

To search for a value in the LabelValue tuple in Java, use the contains() method. It returns a boolean value. TRUE is returned if the value exists, else FALSE is the return value. Let us first see what we need to work with JavaTuples. To work with LabelValue class in JavaTuples, you need to import the following package −import 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 -> Add External Jars and upload the downloaded JavaTuples jar file. Refer the below guide ... Read More

To get the size of the LabelValue tuple in Java, use the getSize() method. Let us first see what we need to work with JavaTuples.

The indexOf() method is inherited from the AbstractList class. It is used to return the index of the first occurrence of the specified element in this list. If the list is empty, it returns -1.The syntax is as follows −public int indexOf(Object ele)Here, ele is the element for which you want the index.To work with the AbstractSequentialList class in Java, you need to import the following package −import java.util.AbstractSequentialList;The following is an example to implement AbstractSequentialList indexOf() method in Java −Example Live Demoimport java.util.LinkedList; import java.util.AbstractSequentialList; public class Demo {    public static void main(String[] args) {       ...

An immutable copy of a LocalTime object where some seconds are added to it can be obtained using the plusSeconds() method in the LocalTime class in Java. This method requires a single parameter i.e. the number of seconds to be added and it returns the LocalTime object with the added seconds.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Demo {    public static void main(String[] args) {       LocalTime lt = LocalTime.now();       System.out.println("The current LocalTime is: " + lt);       System.out.println("The LocalTime with 5 seconds added is: ...

The time in the form of nanoseconds of the day can be obtained using the toNanoOfDay() method in the LocalTime class in Java. This method requires no parameters and it returns the time in the form of nanoseconds of the day.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Main {    public static void main(String[] args) {       LocalTime lt = LocalTime.parse("05:15:30");       System.out.println("The LocalTime is: " + lt);       System.out.println("The nanoseconds of the day are: " + lt.toNanoOfDay());    } }OutputThe LocalTime is: 05:15:30 The nanoseconds of ...
