Sort List of Strings with Localization

Question

I want to sort below List of strings as per user locale

List words = Arrays.asList(
      \"Äbc\", \"äbc\", \"Àbc\", \"àbc\", \"Abc\", \"abc\",         


        

Answer 1

List<MODEL> ulke = new ArrayList<MODEL>();

    Collections.sort(ulke, new Comparator<MODEL>() {
        Collator collator = Collator.getInstance(new Locale("tr-TR"));
        @Override
        public int compare(MODEL o1, MODEL o2) {
            return collator.compare(o1.getULKEAD(), o2.getULKEAD());
        }
    });

Answer 2

You can use a sort with a custom Comparator. See the Collator interface

Collator coll = Collator.getInstance(locale);
coll.setStrength(Collator.PRIMARY);
Collections.sort(words, coll);

The collator is a comparator and can be passed directly to the Collections.sort(...) method.

Answer 3

I think this what you should be using - Collator

The Collator class performs locale-sensitive String comparison. You use this class to build searching and sorting routines for natural language text.

Do something as follows in your comparator -

public int compare(String arg1, Sting arg2) {
    Collator usCollator = Collator.getInstance(Locale.US); //Your locale here
    usCollator.setStrength(Collator.PRIMARY);
    return usCollator.compare(arg1, arg2);
}

And pass an instance of the comparator the Collections.sort method.

Update

Like @Jan Dvorak said, it actually is a comparator, so you can just create it's intance with the desired locale, set the strength and pass it the sort method:

Collactor usCollator = Collator.getInstance(Locale.US); //Your locale here
usCollator.setStrength(Collator.PRIMARY); //desired strength
Collections.sort(yourList, usCollator);
