Question

I have a simple program that reads two .txt files and prints out the number of unique words in each file. I need to write a HashMap that counts the alphabetical characters and prints the three most common and their counts from either file. So basically this was the original question: "Write a character counting method, public static Map getCounts(FileInputStream input), that creates a Map of character counts in a file. Report the three most common alphabetic characters (a-z) and their counts in each file (moby.txt and hamlet.txt).

Here is the code I have so far, I'm having trouble counting characters instead of strings:

public static Map getCounts(FileInputStream input){

Map<String, Integer> map = new HashMap<String, Integer>();

String string;

for(int i = 0; i < string.length(); i++){

char c = (String) (i);

Integer val = map.get(new String());

if(val != null){

map.put(c, new Integer(val + 1));

}else{

map.put(c,1);

}

}

}
