No
Destructors!?
lSince Java provides
garbage collection
•There are no destructors
•But…have you ever
had a destructor do something other than
memory deallocation?
•If you need this –
you must write a named function and call it explicitly!! (maybe called : void cleanup()?)
lIf for some reason you do need some kind of garbage collection done that the garbage collector doesn’t know about (like C or C++ memory allocation is being used-not
recommended!)
•You can write a
method called “finalize()” which the garbage collector will implicitly call if it is provided prior
to releasing memory –
•and then on the
next garbage collection pass it will reclaim the object’s memory
