【java】List元素排序Lambda表达式

List<Student> students = new ArrayList<>();
Student s1 = new Student("haha",12,"女",2);
Student s2 = new Student("xixi",13,"女",4);
Student s3 = new Student("guagua",14,"女",3);
Student s4 = new Student("yaya",15,"女",1);

students.add(s1);
students.add(s2);
students.add(s3);
students.add(s4);

students.sort(Comparator.comparing(Student :: getSort));

for (int i = 0; i < students.size(); i++) {
Student s = students.get(i);
System.out.println(s.getName() + s.getAge() + s.getSex() + s.getSort());
// yaya15女1
// haha12女2
// guagua14女3
// xixi13女4
