DoubleStream forEach() method in Java

Java 8Object Oriented ProgrammingProgramming

The forEach() method of the DoubleStream class performs an action for each element of this stream.

The syntax is as follows:

void forEach(DoubleConsumer action)

Here, DoubleConsumer represents an operation that accepts a single double-valued argument and returns no result. The parameter action is a non-interfering action to perform on the elements.

To use the DoubleStream class in Java, import the following package:

import java.util.stream.DoubleStream;

Create a DoubleStream and add some elements to the stream:

DoubleStream doubleStream = DoubleStream.of(45.7, 67.8, 89.7, 95.6);

Now, display the elements:

doubleStream.forEach(System.out::println);

The following is an example to implement DoubleStream forEach() method in Java:

Example

 Live Demo

import java.util.stream.DoubleStream;
public class Demo {
   public static void main(String[] args){
      DoubleStream doubleStream = DoubleStream.of(45.7, 67.8, 89.7, 95.6);
      doubleStream.forEach(System.out::println);
   }
}

Output

45.7
67.8
89.7
95.6
