The java.util.Random.doubles() method returns an effectively unlimited stream of pseudorandom double values, each between zero (inclusive) and one (exclusive). A pseudorandom double value is generated as if it's the result of calling the method nextDouble().

Syntax

public DoubleStream doubles()

Parameters

No parameter is required.

Return Value

Returns a stream of pseudorandom double values.

Exception

NA

Example:

In the example below, the java.util.Random.doubles() method is used to get a stream of pseudorandom double values.

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

public class MyClass {
  public static void main(String[] args) {
    //creating a random object
    Random rand = new Random();

    //generating a stream of double random numbers
    DoubleStream stream = rand.doubles();

    //printing 10 random numbers from the stream
    stream.limit(10).forEach(System.out::println); 
  }
}
