Sorting two arrays simultaneously

Question

I\'m learning and understanding Java now, and while practising with arrays I had a doubt. I wrote the following code as an example:

Answer 1

You should not have two parallel arrays. Instead, you should have a single array of WestWingCharacter objects, where each object would have a field name and a field number.

Sorting this array by number of by name would then be a piece of cake:

Collections.sort(characters, new Comparator() {
    @Override
    public int compare(WestWingCharacter c1, WestWingCharacter c2) {
        return c1.getName().compareTo(c2.getName();
    }
});

or, with Java 8:

Collections.sort(characters, Comparator.comparing(WestWingCharacter::getName));

Java is an OO language, and you should thus use objects.
