Java's collections framework has long needed a collection type that represents a sequence of elements with a defined encounter order and a uniform set of operations that apply across such collections.

Java provides built-in collection processing features that help developers improve data processing, including the Collections Framework and native parallel processing functions.

Generics in the Java Collections Framework Generics are integrated into Java Collections to provide compile-time type checking and to eliminate the need for explicit type casting.

Proposal for enhancing the Java programming language would define interfaces for sequenced collections, sequenced sets, and sequenced maps.
