Answer 1

If you have object of Entity class (empDet) in JPA then from that object you can get the all properties of that class.

As you know in JPA class represent table in database and properties represent columns of that table.

if you have an object of empDet e.i emp

empDet emp=repository.findByActiveFlag("Y");

Field[] members = emp.getClass().getDeclaredFields();
        for(Field member:members){
            System.out.println(member.getName());
        }
