The legacy **C**‑like array field syntax is confusing in **Java**, and it’s not used for the `@Stable int[]` arrays below.

Suggestion:

        @Stable
        private static final double[] T = {


--------------------------------------------------------------------------------

Or at least put the `T[]` on the same line so that it’s clear why this field has `@Stable`, since regular `static final double`s are already constant folded and @wenshao’s comment[^1] confused me on the “**Conversation**” tab, since it was missing the `T[]` there.

Suggestion:

        @Stable
        private static final double T[] = {
