Counter of total words and without repeating words in a text, using JAVA

Just what the title says, this code counts the total of words in a text and count the words without repeating. For example:

My name is Perez Perez

total words: 5
total without repeating words: 4 (since Perez appear two times)

Hope you got it, now the code:

// don't forget to add the required libraries
public void countWords(String text1 ){

         // text1 is the text whose we want to get the count of words
        ArrayList<String> wordArray = new ArrayList<String>();
        //split the text in an array using spaces to get the words
        String[] words = text1.split(" ");
        //add the word to an ArrayList
        wordArray.addAll(Arrays.asList(words));
        //Create a HashSet
        HashSet hs = new HashSet();
        //next line add to the HashSet the words without repeating
        hs.addAll(wordArray);
        //clean the Array
        wordArray.clear();
        //add to the Array the words without repeating
        wordArray.addAll(hs);
        //print the output
       
        System.out.print("total words: "+words.length); 
        System.out.print("total without repeating words: "+wordArray.size()); 
}
