hey i need to use the same concept of just instead of counting no of occurrences i want to grab there index key values
for ex: string =javais
what that hashmap should look like is {
j:0,
a:1,3

and so on...
}

String s ="Java";
HashMap h = new HashMap();
char []c = s.toCharArray();
for(Character i: c)
{
if(h.containsKey(i))
{
h.put(i,h.get(i)+1);
}
else
{
h.put(i,1);
}
}
Set set = h.keySet();
for(char c2 : set)
{
System.out.println("Char: "+c2+" "+h.get(c2));
}

// Easiest Solution
public static void main(String[] args) {
String text = "Sanjay";
HashMap hashmap = new HashMap();
for(int i=0; i< text.length(); i++)
{
char ch = text.charAt(i);
int count=0;
if(hashmap.containsKey(ch))
{
count = hashmap.get(ch);
}
hashmap.put(ch, ++count);
}
System.out.println(hashmap);
}
