[Solved] how to configure cypal plugins into eclipse [closed]

Using collections framework in Java, a developer has to use loops and make repeated checks. Another concern is efficiency; as multi-core processors are available at ease, a Java developer has to write parallel code processing that can be pretty error-prone.

To resolve such issues, Java 8 introduced the concept of stream that lets the developer to process data declaratively and leverage multicore architecture without the need to write any specific code for it. Using stream, you can process data in a declarative way.

In Java 8, Collection interface has two methods to generate a Stream −

stream() − Returns a sequential stream considering collection as its source.

parallelStream() − Returns a parallel Stream considering collection as its source.

Example:

List<String> strings = Arrays.asList("abc", "", "bc", "efg", "abcd","", "jkl");
List<String> filtered = strings.stream().filter(string -> !string.isEmpty()).collect(Collectors.toList());

The filter() method is used to eliminate elements based on a criteria. Like this there are so many methods in Stream.
