Could someone explain why there is no destructor in Java classes?


The explanation I remember is destructors are generally used to free
memory, and Java has garbage collection. Doesn't make it right, but that
is the way it is.

That's one of the things that bothers me about Java. So many newbe CompSci
people think it is wonderful, but it has so many glaring omissions and all
too often it falls short of a real and useful programing language. Like
Windows, skill in Java comes from knowing the trivia of Java, and not from
the theory and science of your algorithms.

If you have any mixed language objects (i.e. Java objects which have underlying native memory associated), when the object is created memory is allocated in both the Java heap and the C native heap. ... It is important to explicitly call close- otherwise if the object gets promoted to the old area, the memory will not be freed until the object gets garbage collected from the old area which can take a very, very long time (and in the worst case you may have the process hit a memory limit without a garbage collection occurring as only the Java heap's behaviour will trigger garbage collection). ...
