2.精简版

2.1这是Renan创建的简化版本（下面的评论）

package com.mkyong;import java.time.LocalDateTime;
import java.time.ZoneId;
import java.util.AbstractMap.SimpleEntry;
import java.util.Map;public class DisplayZoneAndOffSet2 {public static final boolean SORT_BY_REGION = false;public static void main(String[] args) {LocalDateTime localDateTime = LocalDateTime.now();long total = ZoneId.getAvailableZoneIds().stream().map(ZoneId::of).map(zoneId -> new SimpleEntry<>(zoneId.toString(), localDateTime.atZone(zoneId).getOffset().getId().replaceAll("Z", "+00:00"))).sorted(SORT_BY_REGION? Map.Entry.comparingByKey(): Map.Entry.<String, String>comparingByValue().reversed()).peek(e -> System.out.printf(String.format("%35s (UTC%s) %n", e.getKey(), e.getValue()))).count();System.out.println("\nTotal Zone IDs " + total);}
}

它可以在Java 8中使用，但是由于存在peek()和count()问题 ，因此'peek（）'在Java 9及更高版本中将无法打印

2.2我做了一点修改并返回了一个新的排序图。 经过Java 8和Java 12测试。

package com.mkyong;import java.time.LocalDateTime;
import java.time.ZoneId;
import java.util.AbstractMap.SimpleEntry;
import java.util.LinkedHashMap;
import java.util.Map;
import java.util.stream.Collectors;public class DisplayZoneAndOffSet3 {public static final boolean SORT_BY_REGION = false;public static void main(String[] args) {LocalDateTime localDateTime = LocalDateTime.now();Map<String, String> result = ZoneId.getAvailableZoneIds().stream().map(ZoneId::of).map(zoneId -> new SimpleEntry<>(zoneId.toString(), localDateTime.atZone(zoneId).getOffset().getId().replaceAll("Z", "+00:00"))).sorted(SORT_BY_REGION? Map.Entry.comparingByKey(): Map.Entry.<String, String>comparingByValue().reversed()).collect(Collectors.toMap(SimpleEntry::getKey,SimpleEntry::getValue,(oldValue, newValue) -> oldValue,LinkedHashMap::new));result.forEach((k, v) -> System.out.printf(String.format("%35s (UTC%s) %n", k, v)));System.out.println("\nTotal Zone IDs " + result.size());}
}
