Examples of usage

  • The class uses a getter to return the value.
  • You should call the getter to retrieve the private variable.
  • Using a getter improves data encapsulation.

Etymology

The term 'getter' is derived from the verb 'get', which originates from the Old Norse word 'geta', meaning 'to obtain, reach, or perceive'. The use of 'getter' in programming began to popularize in the late 20th century, especially with the rise of object-oriented programming languages like Java and C++. The practice of using getters and setters is linked to the encapsulation concept, which promotes the idea of restricting direct access to an object's data and providing methods for controlled interaction. This helps maintain the integrity of the data and the internal state of objects.
