Java/Data Type/String sort

Sort array values in case insensitive order

   <source lang="java">

import java.util.Arrays; public class Main {

 public static void main(String[] args) {
   String[] teams = new String[5];
   teams[0] = "M";
   teams[1] = "c";
   teams[2] = "A";
   teams[3] = "l";
   teams[4] = "E";
   Arrays.sort(teams);
   System.out.println(Arrays.toString(teams));
   Arrays.sort(teams, String.CASE_INSENSITIVE_ORDER);
   System.out.println(Arrays.toString(teams));
 }

Sorting a string List

 public static void main(String[] argv) throws Exception {
   String[] strArray = new String[] { "z", "a", "A" };
