如何在Java中对ArrayList进行排序

使用

Comparator

List<Fruit> fruits= new ArrayList<Fruit>();Fruit fruit;for(int i = 0; i < 100; i++){  fruit = new Fruit();  fruit.setname(...);  fruits.add(fruit);}// SortingCollections.sort(fruits, new Comparator<Fruit>() {        @Override        public int compare(Fruit fruit2, Fruit fruit1)        { return  fruit1.fruitName.compareTo(fruit2.fruitName);        }    });

现在，你的水果清单将基于进行排序

fruitName
