Using HashMap need to count the frequency of letters in a String

[Abhinav satyam Gupta]

Hello Friends,

I wanted to write a prog which can count the frequency of letters in a String using HashMap.
Would seek your assistance to do so

You could try creating a HashMap<Character, int>, setting the keys to each letter your interested in. Then iterating through each Character in the String, and if (key<Character> .exists()) { value ++; }


now, there you go in sudo sudo code

That should be HashMap<Character, Integer> of course
And if the key does not exist, you have encountered the first occurrance. It's easy to determine what the value would have to be then.
