DoubleStream mapToInt() method in Java
The mapToInt() function of the DoubleStream class returns an IntStream consisting of the results of applying the given function to the elements of this stream.The syntax is as followsIntStream mapToInt(DoubleToIntFunction mapper)Here, mapper is a stateless function to apply to each element. The DoubleToIntFunction is a function that accepts a double-valued argument and produces an int-valued result.To use the DoubleStream class in Java, import the following packageimport java.util.stream.DoubleStream;The following is an example to implement DoubleStream mapToInt() method in JavaExampleimport java.util.stream.IntStream; import java.util.stream.DoubleStream; public class Demo { public static void main(String[] args) { DoubleStream doubleStream = DoubleStream.of(45.8, 78.9, ...

The forEachOrdered() method of the DoubleStream class in Java performs an action for each element of this stream. This assures that each element is processed in encounter order for streams that have a defined encounter order.The syntax is as followsvoid forEachOrdered(DoubleConsumer action)Here, DoubleConsumer represents an operation that accepts a single double-valued argument and returns no result. The parameter action is a non-interfering action to perform on the elements.To use the DoubleStream class in Java, import the following packageimport java.util.stream.DoubleStream;The following is an example to implement DoubleStream forEachOrdered() method in Java:Exampleimport java.util.stream.DoubleStream; public class Demo { public static void main(String[] ...
