Declarative transaction: you put the transaction declarative in the method declaration. so you doesn't need to implement the transaction manually. Here I give you the example:

// declarative
@Transcational
public void Transfer (Account from, Account destination, double amount) {
//do your logic here
}

// programmatic
public void Transfer (Account from, Account destination, double amount) {
    var session = sessionFactory.openSession();
    var tx = session.BeginTransaction();

    try {
        //do you logic here
        tx.Commit();
    } catch {
        tx.Rolback();
    }
}

Container managed transaction and bean managed transaction, i guess you are referring to Enterprise JavaBean? From my understanding, container managed transaction will not require the developer to explicitly write codes or constructs to manage the transaction, analogous to auto-commits for database.
