Sorry I dont want to give a detailed answer here cos no one e is going to read the code.
You can use Map<Char,List<Integer>> counterMap
Iterate through the length of the string
for(int i=i; i<s.length();i++){
if(counterMap.get(s.getCharAt(i))==nul){
//First time
List<Integer> a= new ArrayList<Integer>();
a.add(i);
counterMap.put(s.getCharAt(i),a);
}else{
counterMap.get(s.getCharAt(i)).add(i);
}
//We can iterate through keySet or entrySet to show the result
}
