> This PR introduces a new efficient API for appending two-digit integers to > StringBuilders and refactors DateTimeHelper to leverage this new > functionality. > > Changes include: > > 1. New `appendPair` method for efficient two-digit integer formatting (00-99): > - Added `AbstractStringBuilder.appendPair(int i)` with core implementation > - Added `JavaLangAccess.appendPair(StringBuilder, int)` for internal access > - Added `System.JavaLangAccessImpl.appendPair(StringBuilder, int)` bridge > - Added `DecimalDigits.appendPair(StringBuilder, int)` public static > utility method > - Enhanced Javadoc documentation for all new methods > > 2. Refactored `DateTimeHelper` to use the new `DecimalDigits.appendPair`: > - Updated `DateTimeHelper.formatTo` methods for `LocalDate` and `LocalTime` > - Replaced manual formatting logic with the new efficient two-digit > appending > - Improved code clarity and consistency in date/time formatting > > These changes improve code clarity and performance when formatting two-digit > numbers, particularly in date/time formatting scenarios.
Shaojin Wen has updated the pull request incrementally with one additional commit since the last revision: Use DecimalDigits.appendPair for formatting in time classes This change modifies the toString() methods in MonthDay, YearMonth, ZoneOffset, and ChronoLocalDateImpl to use DecimalDigits.appendPair for formatting two-digit numbers. This provides a more efficient and consistent way to format these values. Also added a comment in ChronoLocalDateImpl.toString() to explain why get() is used instead of getLong() for performance reasons, as the values are guaranteed to be within the int range for all chronologies.
