Sort a single String in Java

Question

Is there a native way to sort a String by its contents in java? E.g.

String s = \"edcba\"  ->  \"abcde\"

Answer 1

Convert to array of chars → Sort → Convert back to String:

String s = "edcba";
char[] c = s.toCharArray();        // convert to array of chars 
java.util.Arrays.sort(c);          // sort
String newString = new String(c);  // convert back to String
System.out.println(newString);     // "abcde"
