DoubleStream toArray() returns an array containing the elements of this stream. It is a terminal operation i.e, it may traverse the stream to produce a result or a side-effect. After the terminal operation is performed, the stream pipeline is considered consumed, and can no longer be used.
Syntax :
double[] toArray()
Return Value : The function returns an array containing the elements of this stream.
Example :
// Java code for DoubleStream toArray()import java.util.*;import java.util.stream.DoubleStream;  class GFG {      // Driver code    public static void main(String[] args)    {        // Creating a DoubleStream        DoubleStream stream = DoubleStream.of(1.2, 3.3,                                         5.4, 7.1, 9.2);          // Using DoubleStream toArray()        double[] arr = stream.toArray();          // Displaying the elements in array arr        System.out.println(Arrays.toString(arr));    }} |
Output :
[1.2, 3.3, 5.4, 7.1, 9.2]
