2150 inheritance

Question 1

Specialization

Answer 1

“is-a” relationship, specialized form and may overried parent
ex - honda is a car

Question 2

Specification

Answer 2

• parent is abstract/superclass, subclasses implement the behaviour
• like specialization but subclasses fill holes left incomplement by parent
  ex - interface in java

Question 3

Construction

Answer 3

• child inherits most/all functionality, changes behaviour to something different (sub. principle does not hold)
  ex - implement a set class with class lIST

Question 4

Generalization

Answer 4

• modifies behaviour of superclass to be more general (opposite of specialization)
  ex - vehicle is a superclass of car (bad idea)

Question 5

extension

Answer 5

• add new abilities (no overriding)
  ex - stringset inherits from set, but adds string functionality as well

Question 6

limitation

Answer 6

• subclass behaviour is smaller/more restrictive than parent
  stack is a subclass of generic list, but doesnt use generic list’s functions

Question 7

containment

Answer 7

“has-a” relationship, use one class as a data member

Question 8

variance

Answer 8

multiple classes have similar implementations, but no hierarchal relationship

Question 9

combination

Answer 9

> =2 parent classes, uses multiple inheritance
