如何排序的java对象的ArrayList？ [英] How to sort an arraylist of objects java?

问题描述

所以，我想在Java对象的ArrayList

So I want an arraylist of objects in java.

我 object1.number 和 object2.number ， object3.number ，等...但这些对象另外还有其他属性数量，如名称，距离，等...

I have object1.number and object2.number, object3.number, etc... but those objects have other properties besides number, such as name, distance, etc...

因此​​，如果正在整理在一个字符串数组这纯粹是，把一个字符串中时间而让另一个字符串取代其位置......但在 araryList 的对象，我该怎么办呢？

So if it was sorting a string in a array it would just be, put a string in a temporal and let the other string take its place... but in an araryList of objects, how can I do it?

我可以只移动对象的数组中的位置？

Can I just move objects to that position of the array?

感谢。

推荐答案

实现您自己的比较器：

Arrays.sort(yourArray, new Comparator<YourClass>() {
        @Override
        public int compare(YourClass o1, YourClass o2) {
            //compare object properties
        }
});
