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 Arrays.sort([], int startIndex, int endIndex).

 String a = "badabcde";
 char[] chArr = a.toCharArray(); // 'b','a','d','a','b','c','d','e'
 Arrays.sort(chArr, 2, 5);
 System.out.println(new String(chArr)); // this prints baabdcde
