The interfaces java.util.List and java.util.Set extend Collection, representing more specialized data structures and adding more operations and/or constraints. List represents a sequence of ...

Examples of generic types in Java Raw types vs. generics Why use generics? Generics are commonly used in the Java Collections Framework with java.util.List, java.util.Set, and java.util.Map.

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