data in public section and private section swapping no diffrence

[Former Member]

dear all,

my question when we define data type in private or protected section and when we shift these declaration

to public section or if we swap these declaration among these section sometime or every time we find no difference

in output.

and my second question

thanks

When you change the attribute visibility from Private to Public or vice versa, the consumer or user of that class would get affected. So, if you have a global class which has a public attribute which is being used in a program and when you change this to Private attribute, your program would give the runtime error is you run it or syntax error if you compile it.

The same way, when you change the visibility of Protected Attributes to Private Attributes, you need to make sure all of your Subclasses are error free.

For your second question, you define the interface using the INTERFACE and you use this interface in your concrete class using the keyword INTERFACES. You would write the implementation of the methods of this interfaces in this concrete class once your use it with keyword INTERFACES.

Hi tarun,

public protected and private section define the visibility of attributes and methods: PUBLIC can be seen and used from outside and inside the object. PROTECTED is only visible in the class it self and any inherited classes. PRIVATE is visible only in the class.

Attributes should be always private, their values should be used only by SETter and GETter methods. Other languages and development environments like ECLIPSE for JAVA can generate SET and GET methods.

The transition of ABAP is still under way.
