exporting and importing data from class

Hi Experts,

I am new to OO programming and modifying a Webdynpro component to export a context data to a external class. As part of the requirement I want to export a data to external class and later on import the data from the class in another BADI during runtime. I am not sure how to implement this type of class but I assume it has something to do with constructor concept?

Can anyone help me as how to create and use such class?
