java - What if a finalizer makes an object reachable? -

in java, finalize called on object (that overrides it) when it's garbage collectioned, when it's unreachable. if finalizer makes object reachable again, happens then?

the object not collected until gets unreachable again.

according javadoc, finalize() not called again.

java memory-management garbage-collection jvm finalizer
