Java程序使用反向比较器对字符串流进行排序
让我们首先创建一个字符串列表：
List<String> list = Arrays.asList("Tom", "Jack", "Ryan", "Kevin", "Loki", "Thor");现在比较每个元素的反向：
Comparator<String> comp = (aName, bName) -> aName.compareTo(bName);
现在，执行排序：
list.stream().sorted(comp.reversed())
以下是使用反向比较器对字符串流进行排序的示例：
示例
import java.util.Arrays;
import java.util.Comparator;
import java.util.List;
public class Demo {
public static void main(String[] args) {
List<String> list = Arrays.asList("Tom", "Jack", "Ryan", "Kevin", "Loki", "Thor");
System.out.println("Initial List = "+list);
System.out.println("Reverse...");
Comparator<String> comp = (aName, bName) -> aName.compareTo(bName);
list.stream().sorted(comp.reversed()) .forEach(System.out::println);
}
}输出结果
Initial List = [Tom, Jack, Ryan, Kevin, Loki, Thor] Reverse... Tom Thor Ryan Loki Kevin Jack
