Example 1 :

// Java code for LongStream builder()
import java.util.*;
import java.util.stream.Stream;
import java.util.stream.LongStream;

class GFG {

    // Driver code
    public static void main(String[] args)
    {
        // Creating a LongStream using
        // LongStream builder()
        LongStream stream = LongStream.builder().add(0).build();

        // Displaying the elements
        stream.forEach(System.out::println);
    }

        // LongStream builder()
        LongStream stream = LongStream.builder().add(1L).add(3L).add(5L).add(7L).add(9L).build();
