Please let me know what is the difference between the below mentioned two declarations:

Types:Begin of A,

no TYPE i,

name TYPE i,

wage TYPE i,

END OF A.

*I want to know the difference between these three statements:

B TYPE A.

B TYPE TABLE OF A

CLASS_DATA: B TYPE TABLE OF A.

B type A ====creates a Work Area of A structure,

B type table of A === creates an internal table without header line of A structure

3rd one its OOps concept off declaring a STATIC ATTRIBUTES.

TYPES used to declare structures.

DATA is actually where memory allocates

Hello,

Data: B TYPE A.

Creates a work area with the structure of type A.

Data: B TYPE TABLE OF A.

Creates an internal table w/o header line with the structure of type A.

CLASS_DATA: B TYPE TABLE OF A.

Can be included in a class definition and will create a static attribute valid not only for the instances but for the class. The value can be accessed with class=>b.

Regards

hi,

For the first one:

B type A: it will create a work area which will hold only one record at a time similar to the structure defined with TYPES.

B type Table of A : This statement defines an internal table which is similar to the structure that has defined with TYPES.

CLASS-DATA: The statement CLASS-DATA can only be used in the declaration part part of a class or an interface.The statement declares a static attribute which validity is not associated with instances of a class but with the class itself. All instances of the class and its subclasses access the same static attribute.

Thanks,

Sneha
