How to capture values with ArgumentCaptor

argumentCaptor.java

UserDao userDao = Mockito.mock(UserDao.class);
ArgumentCaptor<User> captor = ArgumentCaptor.forClass(User.class);
Mockito.verify(userDao).save(captor.capture());

//do some testing logic, eg. call save on a userService object, 
//which internally uses userDao to save the user object

//get the user as it was passed to the save method in userDao
User user = captor.getValue()
