java使⽤distinct_Java中的Stream.distinct（）⽅法使⽤流类的distinct()⽅法返回由该流的不同元素组成的流。语法如下-Stream distinct()
⽰例
以下是在Stream类中实现distinct()⽅法的⽰例-import java.util.*;
public class Demo {
public static void main(String[] args) {
List list = Arrays.asList(10, 30, 40, 40, 50, 70, 90, 90, 100);
System.out.println("List = "+list);
System.out.println("Displaying only the distinct elements = ");
list.stream().distinct().forEach(System.out::println);
}
}
