Finding repeated words on a string and counting the repetitions

Question

I need to find repeated words on a string, and then count how many times they were repeated. So basically, if the input string is this:

String s = \"House, House         


        

Answer 1

Try this,

public class DuplicateWordSearcher {
@SuppressWarnings("unchecked")
public static void main(String[] args) {

    String text = "a r b k c d se f g a d f s s f d s ft gh f ws w f v x s g h d h j j k f sd j e wed a d f";

    List list = Arrays.asList(text.split(" "));

    Set uniqueWords = new HashSet(list);
    for (String word : uniqueWords) {
        System.out.println(word + ": " + Collections.frequency(list, word));
    }
}

}
