You can use google-gson. Here is a sample code:

    @Test
    public void testGson(){
       Book book = new Book();
       book.code = "1234";
       book.names = new HashMap();
       book.names.put("Manish", "Pandit");
       book.names.put("Some","Name");
       String json = new Gson().toJson(book);
       System.out.println(json);
   }

The output is {"code":"1234","names":{"Some":"Name","Manish":"Pandit"}}
