OOPs Concepts In Java further contribute to its versatility, allowing developers to leverage object-oriented programming principles for efficient and modular code development. Why Is Java Important? In Java, the primary advantage is that it eliminates the need for recompilation. It enables developers ...
4.2. Program to Interface, Not to the Implementation This leads to flexible code that can work with any new implementation of the interface. We should aim to use interfaces as variables, as return types of a method or as the argument type of methods. ...
