How to change ratingStars to string?

Im trying to translate RatingBar numOfStar() method into a string instead of an int. In tried to do numOfStar().ToString and it isnt possible.

How can i go about doing this. Because i want to save it as a string in SQLite database.

public RatingBar ratingbar;


       ratingbar = (RatingBar)findViewById(R.id.ratingBar1);

   private void saveState(){
 book_name = title.getText().toString();
 author = book_author.getText().toString();
 isbn = isbn_number.getText().toString();


 if(mRowId == null){
      long id = mDbHelper.addBook(book_name, author, isbn, ratings);

      if(id > 0 ){

      }
  }else{
     mDbHelper.updateBooks(mRowId, book_name, author, ratings, isbn);

 }

String.valueOf(ratingbar.getRating())

ratingbar.setRating(Float.valueOf("some string"))

I may need to see some more code so that I know what RatingBar numOfStar is defined as, although the toString method in Java starts with a lower case 't' which is important as Java is case-sensitive.

String stringResult = numOfStar();

Use String.valueOf(value) to convert a primitive type to a String.
