如何根据List<Object>中的Object的某一属性对List进行排序？

首先是Object类

public class StuVO {
    private String name;
    private int score;

    public StuVO(String name, int srore) {
        this.name = name;
        this.score = srore;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getScore() {
        return score;
    }

    public void setScore(int srore) {
        this.score = srore;
    }
}

然后是处理的代码

import com.catk.entity.StuVO;

import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;

public class ListSort {

    public static void main(String[] args) {
        List<StuVO> list = new ArrayList<>();
        list.add(new StuVO("AAA",90));
        list.add(new StuVO("BBB",150));
        list.add(new StuVO("CCC",12));
        list.add(new StuVO("DDD",64));
        list.add(new StuVO("EEE",5));
        for(int i = 0;i < list.size();i++){
            System.out.println(list.get(i).getName()+" "+list.get(i).getScore());
        }
        System.out.println("--------");

        Collections.sort(list, new Comparator<StuVO>() {
            @Override
            public int compare(StuVO o1, StuVO o2) {
                int i = o1.getScore() - o2.getScore();
                return i;
            }
        });

        for(int i = 0;i < list.size();i++){
            System.out.println(list.get(i).getName()+" "+list.get(i).getScore());
        }
    }
}

通过Collection.sort进行排序。
