(Thanks to @KevinJ.Chase) You might want to look at the following discussions about sorting arrays of strings, and sorting subsets of arrays of strings in Java (not JavaScript!): http://stackoverflow.com/questions/13335233/sorting-subset-of-string-array-in-java-ignoring-case http://stackoverflow.com/questions/12986386/sorting-an-array-of-strings-with-java — Marcus, Oct 29 '16 at 18:59
I wanted to know if there is a function that could do it. I knew about Arrays.sort but not that it accepts parameters. I had googled it but did not find anything substantial. — Ameya Sinha, Oct 30 '16 at 10:23

Arrays.sort accepts range parameters.

Example sorting array indexes 1 until 3 inclusive:

String[] arr = {"abc", "rst", "pqr", "qwerty", "lmn"};
Arrays.sort(arr, 1, 4);
System.out.println(Arrays.toString(arr));
