("Larry", 18))); //单字段排序-倒序1 personResult = personList.stream() .sorted(Comparator.comparing(Person::getName).reversed()) .collect(Collectors.toList()); assertEquals(personResult, asList( new Person("Larry", 18), new Person("James", 20), new Person("Harry", 18), new ...
We can further clean our code using Java 8 Streams API and write it as: Map<Integer,String>sortedMap = map.entrySet() .stream().sorted(Comparator.comparing(Map.Entry::getValue)) .collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue ...
本文从比较排序相关的两个接口(Comparable和Comparator)讲起,并以代码实例的形式,讲解了Array、List、Stream排序的方法,这应该可以覆盖大部分Java排序的使用场景。 对于其它集合类如Set和Map,一样可以进行排序处理,可以将它们转化为Stream然后再进行排序。

In the second example, we use Java stream to sort theArrayList. The Stream API allows a more powerful way to do sorting. Main.java import java.util.ArrayList; import java.util.List; import java.util.stream.Collectors; void main() { ...
import java.util.List; void main() { List<Integer> vals = Arrays.asList(5, -4, 0, 2, -1, 4, 7, 6, 1, -1, 3, 8, -2); System.out.println("Ascending order"); var sorted1 = vals.stream().sorted().toList(); System.out.println(sorted1); ...

Similar to thechained predicates, we can combine any number ofComparatorsto create any complex sorting logic and sort theStreamitems with it. We can use other Comparator methods as well as documented in theofficial Java docs. Happy Learning !!
