What is the role of interfaces in Object-Oriented COBOL, and how are they different from classes?
- Interfaces are used only for input/output operations.
- Interfaces can be instantiated like classes.
- Interfaces define common behavior, and they cannot have attributes.
- Interfaces have the same characteristics as abstract classes.
In Object-Oriented COBOL, interfaces define common behavior that can be implemented by multiple classes. Unlike classes, interfaces cannot have attributes; they only declare methods. Classes can implement multiple interfaces, enabling them to exhibit behavior from different sources. Interfaces promote a higher level of abstraction and facilitate code modularity and flexibility.
