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

Please use the below code. It is the most simplest as per my analysis. Hope you will like it:

import java.util.Arrays;
import java.util.Collections;
import java.util.HashMap;
import java.util.HashSet;
import java.util.List;
import java.util.Scanner;
import java.util.Set;

public class MostRepeatingWord {

    String mostRepeatedWord(String s){
        String[] splitted = s.split(" ");
        List listString = Arrays.asList(splitted);
        Set setString = new HashSet(listString);
        int count = 0;
        int maxCount = 1;
        String maxRepeated = null;
        for(String inp: setString){
            count = Collections.frequency(listString, inp);
            if(count > maxCount){
                maxCount = count;
                maxRepeated = inp;
            }
        }
        return maxRepeated;
    }
    public static void main(String[] args) 
    {       
        System.out.println("Enter The Sentence: ");
        Scanner s = new Scanner(System.in);
        String input = s.nextLine();
        MostRepeatingWord mrw = new MostRepeatingWord();
        System.out.println("Most repeated word is: " + mrw.mostRepeatedWord(input));

    }
}
