Run Result: 9865421

Using ArrayList and collections

Importjava.util.ArrayList;Importjava.util.Collections; Public classBuble { Public Static voidMain (string[] args) {//TODO auto-generated Method StubString in = "1492586"; StringBuffer Sbuffer=NewStringBuffer (""); ArrayList<Integer> List =NewArraylist<integer>();  for(inti = 0; I < in.length (); i++) {List.add (Integer.parseint (string.valueof (In.charat (i)));        } collections.sort (List);        Collections.reverse (List);        System.out.println (List);  for(inti = 0; I < in.length (); i++) {sbuffer.append (List.get (i)); } String out=sbuffer.tostring ();    System.out.print (out); }}

Operation Result:

[9, 8, 6, 5, 4, 2, 1]
