Object-Oriented Programming

• The hot topic in programming languages:

  • Strong typing, inheritance.
  • Reduces development time, increases reuse?

• Actual benefits appear modest (20-30%?).

• Doesn’t raise level of programming or encourage reuse:

  • Still work with small basic units.
  • Still compiled.
  • Strongly typed interfaces discourage reuse.

• Implementation inheritance is a bad idea:

  • Binds implementations of classes together.
  • Must understand entire class hierarchy.
  • Can’t reuse classes independently.
