Reference Type

Definition:
A data type that stores a reference to an object in memory, rather than the object itself.

Detailed Explanation​

  • The reference points to a memory address where the object is stored (usually in the heap).
  • Variables of reference types do not contain the actual value.
  • Changes through one reference affect all references to the same object.

Example​

// Example in a generic language // Person p1 = new Person("Alex"); // Person p2 = p1; // both refer to the same object
