Copy not null and not empty fields from one object to another object of the same type(Objects are same type) in java
- by Chinni
I am using hibernate, struts, extjs in my project.
I have a Customer object with these fields:
custId,
custName,
address,
phone
and in my project from UI side I get an object customer with custName.
So I need to update the above object(custName is unique). I have only one object with the same customer name. So I will get that object using customer name (object from DB).
Now I have to save the object with the updated customer name.
If I save as follows I have Customer Object from UI, is cust
Customer cust1 = getCustomerByName(cust.getCustName());
cust.setCustId(cust1.getCustId()); save(cust);
If I do this I lose the customer address and phone number.
So, how can I copy one object not null or not empty field values to another object of same type.
Can any one please help. I just stuck here. It's stopping me to save.
Thanks in advance!
