IntStream sequential() returns a sequential IntStream. It may return itself, either because the stream was already sequential, or because the underlying stream state was modified to be sequential. IntStream sequential() is an intermediate operation. Intermediate operations are invoked on a Stream instance and after they finish their processing, they give a Stream instance as output. Syntax :
IntStream sequential()

Where, IntStream is a sequence of primitive
int-valued element.
Example 1 :
// Java code for IntStream sequential()
// to return a sequential IntStream.
import java.util.*;
import java.util.stream.IntStream;
  
class GFG {
  
    // Driver code
    public static void main(String[] args)
    {
        // Creating an IntStream
        IntStream stream = IntStream.of(3, 5, 9, 12, 14);
  
        // Using IntStream sequential()
        IntStream streamNew = stream.sequential();
  
        // Displaying sequential IntStream
        streamNew.forEach(System.out::println);
    }
}

                    
Output:
3
5
9
12
14
Example 2 :
// Java code for IntStream sequential()
// to return a sequential IntStream.
import java.util.*;
import java.util.stream.IntStream;
  
class GFG {
  
    // Driver code
    public static void main(String[] args)
    {
        // Creating an IntStream of elements
        // in range [-2, 4)
        IntStream stream = IntStream.range(-2, 4);
  
        // Using IntStream sequential()
        IntStream streamNew = stream.sequential();
  
        // Displaying sequential IntStream
        streamNew.forEach(System.out::println);
    }
}

                    
Output:
-2
