Relation between SAP-ABAP and Java-Objects

[Former Member]

Hi friends,

I have some doubts related to Sap Objects.

What is the relation between SAP and Java.

What is the middle ware between these 2 platforms.

And SAP is itself having database then why we are going for Java Objects. What is the necessity for the ABAP Objects.

Please tell me the answer with examples

I don't think there is any relation between SAP-ABAP and Java -Objects apart from both being some kind of programming languages.

Due to the inherent advantages of the Object Oriented programming, SAP has introduced the OOPS concepts and called it ABAP Objects.

hi uma,

you are doubt is interesting. It's very simple but logically very good for knowing 2 programming technologies at a time.

ABAP Objects is an object oriented extension of ABAP programming language with almost all standard OO features: inheritance, polymorphism, encapsulation, etc. First ABAP Objects were unofficially introduced in SAP R/3 4.0 - you could only declare local classes. Since SAP R/3 4.6c ABAP classes became another development object. In 4.7 object oriented exceptions were added.

Comparing with old ABAP language, classes have more strict syntax check. Most of old ambiguous ABAP (thus dangerous) constructs and statements are forbidden in ABAP classes - e.g. implicit internal table workarea, omitted type declaration of a variable, etc. The flavour of OO paradigm implemented in ABAP Objects reminds of Java language.

One of special features of ABAP Objects are events - a kind of Publish & Subscribe technology which allows object instances to communicate.

And also check the below websites.

If any issues kindly let me know.

Reward me if it is useful.

And i won't repeat this again.

Thank you very much for the suggestion.
