对两个ArrayList进行排序，一个相对于另一个

Question

I want to sort one ArrayList used to display to the user:

String[] listOne = {whip, amulet, cape};

Then sort a second ArrayList used as backed data relative to the first list being sort:

String[] listTwo = {abyssal_whip, amulet_of_power, strength_cape};

Is there any way I can do this?

Answer 1

Don't store two related pieces of data in separate arrays.

Instead create a custom Object that contains both pieces of data. Then you can implement Comparable on your class or write a custom Comparator to do the sorting for you.

For example check out: Sorting using Comparator- Descending order (User defined classes)

for an example that shows you how to:

1. create a custom Object
2. create a custom Comparator or implement Comparable .
3. use the Collections class to do the sorting.
