Use the String.charAt() method to loop and get each character.
Then have a HashMap.
Whenever you get a character check the map. If it is in there then take the value stored, increase it by one and then put it in the map to replace the old value.
If it is not in the map, just put it with initial value 1.

Check the API for the HashMap class.
