MongoDB Java - How to assign variables from a document -

is there way store variable document in mongodb? have document:

{     "math" : {         "variableone" : 3,         "variabletwo" : 4,     } }

i assign data int variables , add 2 , print out sum.

a simple way write class represents document:

public class math {      private int variableone;     private int variabletwo;      //getters & setters  }

you can use jackson here convert document string object of class math.
