Try "(\\w)\\1+"
The \\w matches any word character (letter, digit, or underscore) and the \\1+ matches whatever was in the first set of parentheses, one or more times. So you wind up matching any occurrence of a word character, followed immediately by one or more of the same word character again.

class Counter {
public int frequency;
}
addWord() then looks like this:
public void addWord (String word) {
Counter c = map.get (word);
if (c == null) {
c = new Counter ();
map.put(word, c);
}
c.frequency ++;
