Introduction to Java 21 Sequenced Collections

Java 21 introduces a new feature called Sequenced Collections, which provides a more efficient way to work with large datasets. Before diving into the details of Sequenced Collections, it’s essential to have a solid understanding of Java Algorithms and data structures. This knowledge will help you appreciate the benefits and trade-offs of using Sequenced Collections in your Java applications.

Sequenced Collections are designed to improve the performance of data-intensive operations, such as filtering, mapping, and reducing. They achieve this by leveraging the power of parallel processing and lazy evaluation. To get the most out of Sequenced Collections, you should also be familiar with SOLID Design Principles in Java, which will help you design and implement efficient and scalable data processing pipelines.

A simple example of using Sequenced Collections in Java 21 is shown below:

 List data = List.of("a", "b", "c");
 SequencedCollection seq = data.sequenced();
 seq.filter(s -> s.startsWith("a")).forEach(System.out::println);

A basic example of using sequenced collections in Java 21 can be seen in the following code snippet:

 List myList = new ArrayList<>();
 // populate the list
 myList.add("Element1");
 myList.add("Element2");
 // utilizing sequenced collection methods
