JSR 396 (Java SE 21): JEP Proposed to Target: 431: Sequenced Collections

[Iris Clark]

The following JEP with scope "SE" has been proposed to target JDK 21:

  431: Sequenced Collections
       https://openjdk.org/jeps/431

  Summary: Introduce new interfaces to represent collections with a
  defined encounter order.  Each such collection has a well-defined first
  element, second element, and so forth, up to the last element.  It also
  provides uniform APIs for accessing its first and last elements, and
  for processing its elements in reverse order.

The announced deadline for feedback to jdk-dev is Thu 16 Mar 23:59 UTC:

    https://mail.openjdk.org/pipermail/jdk-dev/2023-March/007447.html

If there are no unresolved objections at that time, then the JEP will be moved
to the Targeted state, indicating that the feature is expected to appear in
the specified release of the JDK Project.  For more information about states,
see the JEP Process document:
