Java - sort only subsection of array

Question

I have an array of characters

String a = \"badabcde\";
char[] chArr = a.toCharArray(); // \'b\',\'a\',\'d\',\'a\',\'b\',\'c\',\'d\',\'e\'

Answer 1

Use public static void sort(char[] a, int fromIndex, int toIndex) in Arrays class.

In your example:

Arrays.sort(chArr,2,6); // note that fromIndex is inclusive
                        // but toIndex is exclusive
