1、java8Person person1 = new Person("tom", 15);
Person person2 = new Person("jack", 26);
Person person3 = new Person("lucy", 12);
List<Person> list = Arrays.asList(person1,person2,person3);
//正
Comparator< T >接口实现自定义规则排序一、案例Demo二、案例解析三、compare方法的剖析（重）四、总结五、一些拓展 一、案例Demo先上一段代码（出自黑马程序员在B站的java基础课程）public class Demo_Student {
public static void main(String[] args) {
Student s
