final keyword with inheritance in javaThe final keyword is final that is we cannot change. We can use final keywords for variables, methods, and class. If we use the final keyword for the inheritance that is if we declare any method with the final keyword in the base class so the ...
Before delving into the details of the “super” keyword, let’s quickly revisit the concept of inheritance in Java. Inheritance allows a class to inherit properties and behaviors (methods and fields) from another class, promoting code reusability and establishing a hierarchical relationship. The cla...
Interfaces provide a way to achieve abstraction and multiple inheritance in Java. Usage Interfaces are used to specify a set of methods that a class must implement. They are particularly useful for defining a contract that multiple classes can adhere to, ensuring that they provide specific ...
Testing: Final classes and methods might be challenging to mock for unit testing. Consider this while designing your classes. Inheritance: While final classes prevent inheritance, they can limit code reuse. Be sure to balance the benefits of code inheritance with the need for immutability. Thread ...
