LongStream forEachOrdered() method in Java

LongStream forEachOrdered(LongConsumer action) performs an action for each element of this stream in encounter order. LongStream forEachOrdered(LongConsumer action) is a terminal operation i.e, it may traverse the stream to produce a result or a side-effect.

Syntax :

void forEachOrdered(LongConsumer action)

Parameter : LongConsumer represents an operation that accepts a single long-valued argument and returns no result. This is the primitive type specialization of Consumer for long.

Note : forEachOrdered(LongConsumer action) performs an action for each element of this stream, in the encounter order of the stream if the stream has a defined encounter order.

Example 1 :

// Java code for LongStream forEachOrdered
// (LongConsumer action) in Java 8
import java.util.*;
import java.util.stream.LongStream;

class GFG {

    // Driver code
    public static void main(String[] args)
    {
        // Creating an LongStream
        LongStream stream = LongStream.of(2L, 3L, 4L, 5L);

        // Using LongStream.forEachOrdered
        stream.forEachOrdered(System.out::println);
    }
}

Output:

2
3
4
5

Example 2 :

// Java code for LongStream forEachOrdered
// (LongConsumer action) in Java 8
import java.util.*;
import java.util.stream.LongStream;

class GFG {

    // Driver code
    public static void main(String[] args)
    {
        // Creating an LongStream
        LongStream stream = LongStream.range(5L, 11L);

        // Using LongStream.forEachOrdered() on
        // sequential stream
        stream.forEachOrdered(System.out::println);
    }
}

Output:

5
6
7
8
9
10

Example 3 :

// Java code for LongStream forEachOrdered
// (LongConsumer action) in Java 8
import java.util.*;
import java.util.stream.LongStream;

class GFG {

    // Driver code
    public static void main(String[] args)
    {
        // Creating an LongStream
        LongStream stream = LongStream.range(5, 11);

        // Using LongStream.forEachOrdered() on
        // parallel stream
        stream.parallel().forEachOrdered(System.out::println);
    }
}

Output :

5
