I have two
classes Contact.java and PhoneNumber.java
Contact has a many-to-one relationship with PhoneNumber.
My question is if the user deletes the phone number from UI it should be delete from database. To achive this i am doing
this code is deleting the phone number reference from contact but not deleting the record from the phone number table. How to achive this?

Why not just get the phoneNumber, and then call a delete on it? That would delete the object itself.
I agree. Here's the link:
