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

public static void main(String[] args) {
    String str = "helloword";   
    char[] arr;
    List l = new ArrayList();
    for (int i = 0; i < str.length(); i++) {
        arr = str.toCharArray();
        l.add(arr[i]);

    }
    Collections.sort(l);
    str = l.toString();
    System.out.println(str);
    str = str.replaceAll("\\[", "").replaceAll("\\]", "")
            .replaceAll("[,]", "");
    System.out.println(str);

}
