Inheritance is a fundamental concept in object-oriented programming, and it allows you to create new classes (derived or subclass) that inherit properties and behaviors from existing classes (base or superclass). In C++, inheritance is a key feature, and it enables you to establish a hierarchy of classes.

Type conversions between classes in an inheritance hierarchy are referred to as "upcasting" and "downcasting" in Java. When working with polymorphism and inheritance, these conversions are frequently required. Let's look at both ideas:

Overriding methods is a key idea in Java object-oriented programming. It enables a subclass to provide a particular implementation of a method defined in the superclass. When you override a method, you replace the superclass's inherited implementation with your own version in the subclass. This allows for polymorphism and dynamic method dispatch.

In Java, access modifiers are keywords that control the visibility and accessibility of classes, fields, methods, and other members within a class or package.
