The findFirst() method in Java returns an OptionalInt describing the first element of this stream. If the stream is empty, an empty OptionalInt is returned.The syntax is as followsOptionalInt findFirst()Here, OptionalInt is a container object which may or may not contain an int value.To work with the IntStream class in Java, import the following packageimport java.util.stream.IntStream;For OptionalInt class, import the following packageimport java.util.OptionalInt;First, create an IntStream and add elementsIntStream intStream = IntStream.of(30, 45, 70, 80, 90, 120);Now, get the first element of this streamOptionalInt res = intStream.findFirst();The following is an example to implement IntStream findFirst() method in JavaExample Live Demoimport java.util.OptionalInt; ...

The equality of two LocalTime objects can be determined using the equals() method in the LocalTime class in Java. This method requires a single parameter i.e. the LocalTime object to be compared. Also it returns true if both the LocalTime objects are equal and false otherwise.A program that demonstrates this is given as followsExample Live Demoimport java.time.*; public class Main {    public static void main(String[] args) {       LocalTime lt1 = LocalTime.parse("23:15:30");       LocalTime lt2 = LocalTime.parse("23:15:30");       System.out.println("The LocalTime lt1 is: " + lt1);       System.out.println("The LocalTime lt2 is: " + ...

The sorted() method in Java IntStream class is used to return a stream consisting of the elements of this stream in sorted order.The syntax is as followsIntStream sorted()The sorted() method returns the new stream. To work with the IntStream class, you need to import the following packageimport java.util.stream.IntStream;Create an IntStream and add some elementsIntStream intStream = IntStream.of(30, 50, 70, 120, 150, 200, 250, 300);Now, to sort the above stream elements, use the sorted() methodintStream.sorted() The following is an example to implement IntStream sorted() method in JavaExample Live Demoimport java.util.stream.IntStream; public class Demo {    public static void main(String[] args) { ...

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. ...
