The derived class can have its functionality extended. Objects only reveal internal mechanisms that are relevant for the use of other objects, hiding any unnecessary implementation code. This characteristic of data hiding provides greater program security and avoids unintended data corruption. They are only able to call a list of public functions or methods. Other objects do not have access to this class or the authority to make changes. The implementation and state of each object are privately held inside a defined class. This principle states that all important information is contained inside an object and only select information is exposed. Object-oriented programming is based on the following principles: This image shows an example of the structure and naming in OOP. Class attributes belong to the class itself. Objects will have data stored in the attributes field.
