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

    String a ="dgfa";
    char [] c = a.toCharArray();
    Arrays.sort(c);
    return new String(c);

Note that this will not work as expected if it is a mixed case String (It'll put uppercase before lowercase). You can pass a comparator to the Sort method to change that.
