What part of memory is used for interfaces and abstract classes?
Interfaces and abstract classes are part of the application programming interface for the Java language, but are never instantiated in their own right when a Java program is run. Only objects are instantiated in the Java Runtime Environment (JRE) and held in a division of the program’s memory allocation called the heap. Stack memory holds primitive values and the memory addresses of objects on the heap. Actions: Follow-up, clarify or correct this answer. Submit a new question.
