DoubleStream forEachOrdered() method in Java
  • Last Updated : 06 Dec, 2018

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

Syntax :

void forEachOrdered(DoubleConsumer action)

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

Note : forEachOrdered(DoubleConsumer 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 DoubleStream forEachOrdered
// (DoubleConsumer action) in Java 8
import java.util.*;
import java.util.stream.DoubleStream;
  
class GFG {
  
    // Driver code
    public static void main(String[] args)
    {
        // Creating an DoubleStream
        DoubleStream stream =
          DoubleStream.of(2.2, 3.3, 4.4, 5.5);
  
        // Using DoubleStream.forEachOrdered
        stream.forEachOrdered(System.out::println);
    }
}
Output:
2.2
3.3
4.4
5.5

Example 2 :




// Java code for DoubleStream forEachOrdered
// (DoubleConsumer action) in Java 8
import java.util.*;
import java.util.stream.DoubleStream;
  
class GFG {
  
    // Driver code
    public static void main(String[] args)
    {
        // Creating an DoubleStream
        DoubleStream stream = 
              DoubleStream.of(5.3, 6.4, 7.3, 6.1);
  
        // Using DoubleStream.forEachOrdered() on
        // parallel stream
        stream.parallel().forEachOrdered(System.out::println);
    }
}
Output:
5.3
6.4
7.3
6.1
