write json to String instead of file in java

I am using jackson for converting POJO to JSON 

     User user = new User();
    user.setAge(25);
    user.setName("Shahid");

     ObjectMapper mapper= new ObjectMapper();
     mapper.writeValue("D:/test.json", user);

instead of writing it to file , I want to write it to on String variable (jsonString) . So that I get the result as follow.

String jsonString= "{"name" : "Shahid","age" : 25}";

You can try this:

OutputStream os = new ByteArrayOutputStream();
mapper.writeValue(os, user);
String json = os.toString();

You can try,

mapper.writeValueAsString(user).

Please refer documentation for more details.
