DateTimeFormatter to serialize LocalDate as ordinal 1st/2nd/3rd of a month [duplicate]

This question already has an answer here:




  • Printing date in java with ordinal characters [duplicate]

    1 answer




I'd like to display LocalDate as:



first day: 1st;

second day: 2nd;

third day: 3rd;

all rest days: Nth.


e.g. 1980-10-1 as 1st Oct 1980



I'm able to serialize it excluding the first 3 days using DateTimeFormatter.ofPattern("dth MMM yyyy").
Since the first 3 days have a different pattern than the rest days, how to construct the formatter to serialize also the first 3 days?

here is what you are searching : https://docs.oracle.com/javase/8/docs/api/java/time/format/DateTimeFormatterBuilder.html#appendText-java.time.temporal.TemporalField-java.util.Map-



and here is an exemple :



DateTimeFormatterBuilder builder = new DateTimeFormatterBuilder();

Map<Long, String> mapToRoman = new HashMap<>();

mapToRoman.put(1L, "1st");

mapToRoman.put(2L, "2nd");

mapToRoman.put(3L, "3rd");

mapToRoman.put(4L, "4th");

// continue to map all available days in a month

builder.appendText(ChronoField.DAY_OF_MONTH, mapToRoman );

builder.append(DateTimeFormatter.ofPattern(" MM yyyy", Locale.US));

DateTimeFormatter formatter = builder.toFormatter();

  • Is there a simpler way to just add 4 patterns (since it has only 4 different patterns) instead of adding all of 31 days?

  • @LunaticJape - Sort of - a similar answer here uses the same logic, but puts coverage for all 31 days in a few lines

Origin of the phrase “under your belt”?

Image
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0; } 17 1 Today, I found myself discussing what students should have "under their belts" during a lecture, and I wondered to myself if there was some inappropriate undertone here that I might be unaware of. Question : What is the origin of the phrase "under your belt"? A google search revealed some webpages (e.g. [1]) that assert its origin is related to consumption of food -- once a meal has been eaten, it's under your belt (which is a relief). However, with such websites, I have no way to determine fact from "random guy on the internet making stuff up". etymology idioms ...
