Question

I am so confused right now. I am supposed to write a program that uses a hashtable. The hashtable holds words along with their frequency of use. The class “Word” holds a counter and the string. If the word is already in the table then its frequency increases. I have been researching how to do this but am just lost. I need to be pointed in the right direction. Any help would be great.

Answer 1

Hashtable<String, Word> words = new Hashtable<String, Word>();

public void addWord(String s) {
    if (words.containsKey(s) {
        words.get(s).plusOne();
    } else {
        words.put(s, new Word(s));
    }
}

This will do it.
