Java 8Object Oriented ProgrammingProgramming

The DoubleStream.generate() method returns an infinite sequential unordered stream where each element is generated by the provided DoubleSupplier.

The syntax is as follows −

static DoubleStream generate(DoubleSupplier s)

Here, s is the DoubleSupplier for generated elements. The DoubleSupplier represents a supplier of double-valued results.

To use the DoubleStream class in Java, import the following package −

import java.util.stream.DoubleStream;

The following is an example to generate Infinite stream of Double in Java with DoubleStream.generate() method −

Example

import java.util.stream.*;
import java.util.*;

public class Demo {
   public static void main(String[] args) {
      Random r = new Random();
      DoubleStream.generate(r::nextDouble).forEach(System.out::println);
   }
}

Here is the output displaying an infinite stream of Double −
