Get the list of invoking method name's from Hashmap put()

Can you help me to get the list method name's from the HashMap put method.

 Book book= new Book();
        book.setTitle("The Little Prince");
        book.setAuthor("Antoine de Saint-Exupery");
        book.setPrize(9.99);
        book.setPublisher("Delux Pop-up book");
        
        
        HashMap<String,String> map= new HashMap<String,String>();
        map.put("title",book.getTitle());
        map.put("author",book.getAuthor());
        map.put("prize",String.valueOf(book.getPrize()));
        map.put("publisher",validatePuplisher(book.getPublisher()));
        

Excepted result is : book.getTitle(),book.getAuthor(),String.valueOf(book.getPrize()),validatePuplisher(book.getPublisher()) ie just method name's not value from the method.
