The month name for a particular LocalDate can be obtained using the getMonth() method in the LocalDate class in Java. This method requires no parameters and it returns the month name in the year.A program that demonstrates this is given as followsExample Live Demoimport java.time.*; public class Demo {    public static void main(String[] args) {       LocalDate ld = LocalDate.parse("2019-02-14");       System.out.println("The LocalDate is: " + ld);       System.out.println("The month is: " + ld.getMonth());    } }OutputThe LocalDate is: 2019-02-14 The month is: FEBRUARYNow let us understand the above program.First the LocalDate is displayed. ...

To create LabelValue tuple from an array, use the fromArray() method. First, create an array and add elements to it. After that, use the fromArray() method to create a Tuple and set the array in it.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 ... Read More

The concat() method in the LongStream class creates a concatenated stream whose elements are all the elements of the first stream followed by all the elements of the second stream.The syntax is as follows.static LongStream concat(LongStream one, LongStream two)Here, parameter one is the 1st stream, whereas two is the 2nd stream. The method returns the concatenation of both the streams.To use the LongStream class in Java, import the following package.import java.util.stream.LongStream;Create a LongStrem and add some elements.LongStream streamOne = LongStream.of(100L, 150L, 300L, 500L);Now, create another stream.LongStream streamTwo = LongStream.of(200L, 250L, 400L, 600L, 550L);To concatenate both the above streams, use the ...

The day of the year for a particular LocalDate can be obtained using the getDayOfYear() method in the LocalDate class in Java. This method requires no parameters and it returns the day of the year which can be in the range of 1 to 365 and also 366 for leap years.A program that demonstrates this is given as followsExample Live Demoimport java.time.*; public class Demo {    public static void main(String[] args) {       LocalDate ld = LocalDate.parse("2019-02-14");       System.out.println("The LocalDate is: " + ld);       System.out.println("The day of the year is: " + ld.getDayOfYear()); ...

Create Decade Tuple in Java using a constructor or with() method. Here, we will see how to create a Decade of Tuple using constructor.Let us first see what we need to work with JavaTuples. To work with Decade class in JavaTuples, you need to import the following package −import 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 -> Add External Jars and upload the downloaded JavaTuples jar file. Refer the below guide for all the steps to run JavaTuples −Steps − How ... Read More

The day of the month for a particular LocalDate can be obtained using the getDayOfMonth() method in the LocalDate class in Java. This method requires no parameters and it returns the day of the month which can be in the range of 1 to 31.A program that demonstrates this is given as followsExample Live Demoimport java.time.*; public class Demo {    public static void main(String[] args) {       LocalDate ld = LocalDate.parse("2019-02-14");       System.out.println("The LocalDate is: " + ld);       System.out.println("The day of the month is: " + ld.getDayOfMonth());    } }OutputThe LocalDate is: 2019-02-14 ...

The distinct() method in the LongStream class returns a stream consisting of the distinct elements of this stream.The syntax is as follows.LongStream distinct()To use the LongStream class in Java, import the following package.import java.util.stream.LongStream;Create a LongStream and add elements.LongStream longStream = LongStream.of(100L, 150L, 100L, 300L, 150L, 500L);Now, get the distinct elements.longStream.distinct().The following is an example to implement LongStream distinct() method in Java. Here, we have repeated elements in the stream.Example Live Demoimport java.util.stream.LongStream; public class Demo {    public static void main(String[] args) {       LongStream longStream = LongStream.of(100L, 150L, 100L, 300L, 150L, 500L);       System.out.println("Distinct elements..."); ...
