Return value

The method returns an array of the double type.

Code

import java.util.Arrays;
import java.util.stream.DoubleStream;
class Main {
    public static void main(String[] args) {
        DoubleStream doubleStream = DoubleStream.of(5.6, 10.9, 12.4, 34.2, 0.00032);
        double[] doubleArray = doubleStream.toArray();
        System.out.println("Converting the DoubleStream to an array - " + Arrays.toString(doubleArray));
    }
}

Explanation

  • Lines 1 and 2: We import the Arrays class and the DoubleStream interface.
  • Line 6: We create a stream of double values.
  • Line 7: We convert the stream to a double type array using the toArray() method.
  • Line 8: We print the double type array.
