Why method is not throwing Exception

Question

In this method i used SessionFactory.openSession() to get hibernate Session :

public static Session getSession() {
    Session session = null;
    if (factory == null) {
        session = initSessionFactory().openSession(); //initSessionFactory() returns SessionFactory object.
    } else {
        session = factory.openSession();
    }
    return session;
}

since, the method SessionFactory#openSession() throws HibernateException, then why doesn't my method throw an Exception, why there is not any CompileTime Error?

You use openSession to get a Session? I use openSession to **open** a Session! And i use **getSession** to get a Session. (your factory is always `null`?) ;D — Grim, May 06 '14 at 12:34

HibernateException extends RuntimeException.

Because HibernateException is RuntimeException just like NullPointerException

Inheritance hierarchy is

RuntimeException -> NestedRuntimeException -> HibernateException

HibernateException inherits from RuntimeException. You don't have to catch or declare RuntimeExceptions.

See RuntimeExceptions

HibernateException extends RuntimeException, therefore making it an unchecked exception.

Unchecked exceptions don't need to be caught
