inheritance

• The theory behind inheritance is that the world is best represented by a hierarchy

  • this hierarchy will help with code reuse

When to use

• When not create wide or deep object hierachies

• Ideally, should have one level where subclasses are the leafs of the superclass

Why bad?

• leads to more brittle systems and defects

  • told to favour composition over inheritance as getting inheritance correct is difficult

• A lot of patterns were created to overcome the usage of inheritance
