使用自定义排序顺序对对象的ArrayList进行排序

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

public class CustomSort {

    public static void main(String[] args) {
        ArrayList<MyObject> list = new ArrayList<>();
        list.add(new MyObject("Object 1", 5));
        list.add(new MyObject("Object 2", 3));
        list.add(new MyObject("Object 3", 1));
        list.add(new MyObject("Object 4", 4));

        Collections.sort(list, new MyObjectComparator());

        for (MyObject obj : list) {
            System.out.println(obj.getName() + " - " + obj.getValue());
        }
    }

    private static class MyObject {
        private String name;
        private int value;

        public MyObject(String name, int value) {
            this.name = name;
            this.value = value;
        }

            return name;
        }

        public int getValue() {
            return value;
        }
    }

    private static class MyObjectComparator implements Comparator<MyObject> {
        @Override
        public int compare(MyObject o1, MyObject o2) {
            return Integer.compare(o1.getValue(), o2.getValue());
        }
    }
