Try this code

HashMap<Character,Integer> map = new HashMap<Character,Integer>();          
String s = "aasjjikkk";
for(int i = 0; i < s.length(); i++)
{
   char c = s.charAt(i);
   Integer val = map.get(new Character(c));
   if(val != null)
   {
     map.put(c, new Integer(val + 1));
   }
   else
   {
     map.put(c,1);
   }
}
