      ObjectMapper mapper = new ObjectMapper(); 
      String jsonString = "{\"rollNo\":1,\"name\":\"Marks\"}"; 

      try { 
         Student student = mapper.readerFor(Student.class).readValue(jsonString);
         System.out.println(student.name); 
      }
      catch (IOException e) {
         e.printStackTrace(); 
      }   
   } 
}
class Student {
