Sorting multiple ArrayList synchronously
I have multiple parallel ArrayList, I am sorting one of them (i.e. indexes).
ArrayList<Integer> indexes = {2,3,1};
ArrayList<String> names = {"two","three","one"};
ArrayList<String> upper = {"TWO","THREE","ONE"};
I want to synchronise the sorting of the ArrayList 'indexes' with the others ArrayList. I am wondering in the Collections.sort(list) would give me a clue?
