Java 8 Streams
This tutorial will help you have a deep view of Java 8 Streams: what they are, ways to create them, how they work with intermediate operations, terminal operation...
This is an example of a Stream:
List numbers = Arrays.asList(1, 2, 3, 4, 5, 6, 7, 8, 9); // get List from Stream Operation List result = numbers.stream() .filter(i -> (i % 2) == 0) .map(i -> "[" + i + "]") .collect(Collectors.toList()); System.out.println(result);
Run the code above, the console shows:
[, , , ]
Now, we have concept of using a Stream is to enable functional-style operations on streams of elements. Those operations are composed into a stream pipeline which consists of:
Intermediate Operations >
