Example 1 :
// Java code for DoubleStream builder()import java.util.*;import java.util.stream.Stream;import java.util.stream.DoubleStream;  class GFG {      // Driver code    public static void main(String[] args)    {        // Creating an DoubleStream using        // DoubleStream builder()        DoubleStream stream = DoubleStream.builder()                                  .add(2.3)                                  .build();          // Displaying the elements        stream.forEach(System.out::println);    }} |
Output :
2.3
Example 2 :
// Java code for DoubleStream builder()import java.util.*;import java.util.stream.Stream;import java.util.stream.DoubleStream;  class GFG {      // Driver code    public static void main(String[] args)    {        // Creating an DoubleStream using        // DoubleStream builder()        DoubleStream stream = DoubleStream.builder().        add(2.3).add(-1.2).add(3.5).add(10.74).build();          // Displaying the elements        stream.forEach(System.out::println);    }} |
