，主题是“Android-java-如何按对象内的某个值对对象列表进行排序”。文章分为介绍、排序方法、案例代码和四个部分。

import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;
class Student {
    private String name;
    private int score;
    public Student(String name, int score) {
        this.name = name;
        this.score = score;
    }
    public String getName() {
        return name;
    }
    public int getScore() {
        return score;
    }
}
public class Main {
    public static void main(String[] args) {
        List students = new ArrayList<>();
        students.add(new Student("Alice", 80));
        students.add(new Student("Bob", 90));
        students.add(new Student("Charlie", 70));
        // 使用Comparator接口按照分数属性对学生列表进行排序
        Collections.sort(students, new Comparator() {
            @Override
            public int compare(Student student1, Student student2) {
                return student1.getScore() - student2.getScore();
            }
        });
        // 打印排序后的学生列表
        for (Student student : students) {
            System.out.println(student.getName() + ": " + student.getScore());
        }
    }
}
