IntStream builder() returns a builder for an IntStream.

Syntax :

static IntStream.Builder builder()

Parameters :

IntStream.Builder : A mutable builder for an IntStream. A stream builder has a lifecycle, which starts in a building phase, during which elements can be added, and then transitions to a built phase, after which elements may not be added.

Return Value : The function returns a builder for an IntStream.

Example 1 :

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

Output :

-1

Example 2 :

// Java code for IntStream builder()
import java.util.*;
import java.util.stream.Stream;
import java.util.stream.IntStream;
  
class GFG {
  
    // Driver code
    public static void main(String[] args)
    {
        // Creating an IntStream using
        // IntStream builder()
        IntStream stream = IntStream.builder()
                              .add(-1).add(0).add(2).add(4).add(7).build();
