public static void main(String[] args)
String str = "123abc1cd";
char[] strS = new char[str.length()];
List<String>list = new ArrayList<String>();
for (int i = 0; i < str.length(); i++)
      strS[i] = str.charAt(i);
      String strIndex = String.valueOf( strS[i]);
      list.add(strIndex);

List<String> listTemp= new ArrayList<String>();  
Iterator<String> it=list.iterator();  
while(it.hasNext())  
 String a=it.next();  
 if(listTemp.contains(a))  
  it.remove();  
   
 else  
  listTemp.add(a);  
   
 
for(String i:list)  
 System.out.println(i);
