From ae6ff90f5ae31f6e67ad99be9c35c7a92b2da875 Mon Sep 17 00:00:00 2001 From: Shai Almog <67850168+shai-almog@users.noreply.github.com> Date: Sat, 17 Oct 2026 15:07:57 +0300 Subject: [PATCH 01/49] Add pure-logic Java class library additions to JavaAPI and CLDC11 java.util.function, java.util.stream, java.time, java.text, collections, java.util.concurrent, non-file java.io streams, java.lang members, MessageDigest/SecureRandom, charsets and UUID. Host-backed APIs (files, nio.file, prefs, logging, URL, resource bundles, service loader, modules) are left as on master. JdkHost is a narrow internal hook.

Each +/// subpattern is a prefix, a number and a suffix. In the number: +/// +/// - `0` is a digit that is always written, `#` a digit written only when +/// it is significant. +/// - `.` is the decimal separator and `,` the grouping separator; the +/// distance from the last `,` to the end of the integer part is the group +/// size. +/// - `E` followed by one or more `0` selects scientific notation, with at +/// least that many exponent digits. With more integer digit positions than +/// `0`s among them (`##0.###E0`), the exponent is kept a multiple of the +/// number of integer positions. +/// +/// In a prefix or suffix, `%` multiplies the number by 100 and writes a +/// percent sign, the per mille sign multiplies by 1000, the currency sign +/// writes the currency symbol (doubled, the international currency code), and +/// `-` writes the minus sign. A single quote makes the characters up to the +/// next one literal, and two in a row stand for one quote. +/// +/// The characters actually written -- separators, minus, percent, currency +/// -- come from the format's [DecimalFormatSymbols]. +/// +/// #### Rounding +/// +/// Rounding is half-even, the JDK default, and like the JDK it is decided by +/// the exact binary value of a `double`: `0.125` is a true tie and formats as +/// `0.12` under `0.00`, while `0.15`, which as a `double` lies just below the +/// decimal `0.15`, formats as `0.1` under `0.0`. +/// +/// The JDK departs from half-even in two places, and so does this class, +/// because a last digit that differs from the desktop's is worse than either +/// answer: a whole number rounds a tie up in scientific notation (`12345` +/// under `0.###E0` is `1.235E4`), and `5E-4`, `5E-5` and so on round down +/// when the 5 is the first digit dropped (`0.0005` under `0.000` is `0.000`). +/// +/// #### Differences from the JDK +/// +/// - No `setRoundingMode`, `setCurrency`, `setParseBigDecimal` or +/// `formatToCharacterIterator`: the device has none of the types they name. +/// - No localized patterns (`applyLocalizedPattern`, `toLocalizedPattern`). +public class DecimalFormat extends NumberFormat { + + private static final long serialVersionUID = 1L; + + /// The currency sign of a pattern.

{@code String.format} used to be a native method. Its Objective-C branch built an - * argument vector by hand, threw away the string it formatted, and returned - * {@code fromNSString([NSString init])} -- sending {@code init} to the {@code NSString} - * class object, which aborts the process with - * {@code +[NSString init]: cannot init a class object}. Because that branch is behind - * {@code #if defined(__APPLE__) && defined(__OBJC__)} and this suite runs on Linux in CI, - * nothing ever executed it. The C fallback that CI did run silently ignored width and - * precision, so {@code "%.3f"} rendered every digit of the double.

- * - *

Formatting is now plain Java shared by every target, so this one test covers the - * iOS behavior too. It runs the same program on the JVM and under ParparVM and requires - * the two renderings to be identical, case by case -- which pins the output against the - * real {@code java.util.Formatter}, not against a hand-written expectation.

deadlines are overflow safe for any clock origin. - Comments for the ideographic blocks and BufferedWriter locking. - windows-arm64 hello RAM baseline.

(svn+ssh). DateTimeFormatter parses ZZZZ as the localized GMT offset it prints. WeakHashMap compares with the queried key's equals. Properties keeps the empty entry a last line of only a backslash makes.

Int/Long/DoubleSummaryStatistics print the JDK's summary. A CompletableFuture dependent completed by hand skips its action. A reversed view hands bulk changes to the backing list, so an unmodifiable one refuses even a no-op. NavigationTest uninstalls its static dispatcher and LocalContinuityTest clears it: one left behind answered a Form for any route and made an unknown route restorable. linux-x64 objectAllocation RAM recorded lower.
