Java8中Stream的特性有哪些

@Beforepublic void init() { random = new Random(); stuList = new ArrayList<Student>() { { for (int i = 0; i < 100; i++) { add(new Student("student" + i, random.nextInt(50) + 50)); } } };}public class Student { private String name; private Integer score; //-----getters and setters-----}//1列出班上超过85分的学生姓名，并按照分数降序输出用户名字@Testpublic void test1() { List<String> studentList = stuList.stream() .filter(x->x.getScore()>85) .sorted(Comparator.comparing(Student::getScore).reversed()) .map(Student::getName) .collect(Collectors.toList()); System.out.println(studentList);}
