Interface

What is an Interface​

A user interface acts as a contractual arrangement that specifies how different software elements should interact with each other. It defines a set of methods that a class must implement, ensuring consistency and interoperability between different parts of the system.

Importance of Interface​

Interfaces are essential to maintain modularity, extensibility, and code reusability in software development. By defining clear boundaries and expectations of how components communicate, interfaces facilitate collaboration between developers and enable the integration of different modules into compatible systems.

How to Configure an Interface​

  • Within the Settings menu, select the Interface tab. By default, the interface settings will be displayed. Click on the Edit button.
