In object-oriented technology, the part that defines superclass–subclass relationships is inheritance.

Quick Scoop: Core Answer

  • A superclass is the more general, parent class from which other classes derive.
  • A subclass is a more specialized class that extends the superclass and reuses or overrides its behavior.
  • The mechanism that defines and connects these two (who is parent, who is child) is inheritance.

So, if your exam or quiz asks:

“What part of object-oriented technology defines superclass and subclass relationships?”

The correct one-word answer is:

Inheritance ✅

Tiny Illustration

Imagine a class Animal and a class Dog:

  • Animal is the superclass (general: can eat, sleep).
  • Dog is the subclass (more specific: can bark, fetch).
  • The fact that Dog “is an” Animal and automatically gets eat() and sleep() is exactly what inheritance defines.
