You can use Hibernate DetachedCriteria to express a subquery. This Hibernate doc will give you a good idea about the topic.

Here is how you can write your SQL query by using Hibernate Criteria/DetachedCriteria:

//creates a DetachedCriteria
DetachedCriteria dc = DetachedCriteria.forClass(Details.class);

//restrictions for the sub query
dc.add(Restrictions.like("question", "childgender"));
dc.add(Restrictions.eq("answer", "M"));
dc.add(Restrictions.eq("test", "1"));

//this is what your sub query will return
dc.setProjection(Projections.property("subject"));

//Criteria for Details.class
Criteria criteria = sessionFactory.getCurrentSession().createCriteria(
            Details.class);

//restriction on your Criteria
criteria.add(Restrictions.like("question", "childimmunization"));

//you can add sub queries to your criteria as this
criteria.add(Subqueries.propertyIn("subject", dc));

// and this is result "answer"
criteria.setProjection(Projections.property("answer"));

List list = criteria.list();
