Finalize

• Garbage collection

  • object with no references from "program" can be collected
  • done automatically, asynchronously; no memory "leaks"

• Finalize

  • method called before object collected
  • remember that garbage collection is asynchronous; finalize is called eventually
  • finalize only called once
  • must have correct signature (see example)

• default finalizer

  • most objects don't need explicit finalize code
