BlackTom AI · Accepted Answer

Here we examine what in object-oriented programming (OOP) lets you create new classes that reuse code from existing ones.
Option Static: Static members belong to a class rather than an instance, and they don’t inherently provide reuse of code through a new subclass. They are about scope and shared access, not about composing new classes from existing ones.
Option Global: Global is not a formal OOP mechanism for code reuse between classes; it usually refers to scope or accessibility at a broader program level, not a structural inheritance feature.
Option Inheritance: This is the relevant concept. Inheritance enables a new class (a subclass) to reuse fields and methods defined in an existing class (a base or parent class). The subclass can extend or override behavior, achieving code reuse and polymorphic behavior.
Option Encapsulation: Encapsulation focuses on bundling data with methods and restricting direct access to some of an object's components. While important for design, it does not by itself provide a mechanism for reusing code from existing classes to create new ones.
In summary, the mechanism that directly supports reusing code from an existing class to create a new class is inheritance, whereas the other options refer to different OOP concepts that do not fulfill this specific role.
