Insensitive Sorting with comparator

How can I sort Strings with String.CASE_INSENSITIVE_ORDER, using collator or comparator? Actually, how can i combine them?

Comparator comparator=(Collator.getInstance(Locale.forLanguageTag(inputs.getLocale())));

Collections.sort(lines,String.CASE_INSENSITIVE_ORDER);

String.CASE_INSENSITIVE_ORDER is itself a static Comparator.

https://docs.oracle.com/javase/7/docs/api/java/lang/String.html#CASE_INSENSITIVE_ORDER

You can chain multiple comparators by using thenComparing eg. 

Comparator<String> cmp = Comparator.comparingInt(String::length)
             .thenComparing(String.CASE_INSENSITIVE_ORDER);
