Since Sequenced Collections were introduced in Java 21, an article explaining them could be added to the section [The Collections Framework](https://dev.java/learn/api/collections-framework/). Alternatively, information about sequenced collections could be added to [Getting to Know the Collection Hierarchy](https://dev.java/learn/api/collections-framework/organization/) and [Using Maps to Store Key Value Pairs](https://dev.java/learn/api/collections-framework/maps/).
