Java如何根据偏移获得缩写

Question

我有偏移值像UTC + 3我想在java中缩写它

Answer 1

this的改编可能有用。

Set<String> allZones = ZoneId.getAvailableZoneIds();
        LocalDateTime dt = LocalDateTime.now();

        List<String> zoneList = new ArrayList<>(allZones);
        Collections.sort(zoneList);

        zoneList.stream().map((s) -> ZoneId.of(s)).forEach((zone) -> {
            ZonedDateTime zdt = dt.atZone(zone);
            ZoneOffset offset = zdt.getOffset();
            String out = String.format("%35s %10s%n", zone, offset);
            if (offset.getTotalSeconds() == 10800) {
                System.out.printf(out);
            }
        });
