A bit of conjecture here. It is possible for an object to be finalized and garbage collected even if there are references to it in local variables on the stack, and even if there is an active call to an instance method of that object on the stack! The requirement is that the object be … Read more
Although the question was asking about the Object.finalize method, the subject really is about the finalization mechanism as a whole. This mechanism includes not only the surface API Object.finalize, but it also includes specifications of the programming language about the life cycle of objects, and practical impact on garbage collector implementations in JVMs. Much has … Read more
See its very simple. If you are dealing with unmanaged resources – Implement both Dispose and Finalize. Dispose is to be called by developers to free up the resources as soon as they see it that its no longer needed for them. If they forget to call Dispose then Framework calls the finalize in its … Read more
I answer your question with another question: Why finalize method shouldn’t be protected? In general, you should try to keep things as much private as possible. That’s what encapsulation is all about. Otherwise, you could make everything public. finalize can’t be private (since derived classes should be able to access it to be able to … Read more
finalize and other approaches that use GC knowledge of objects lifetime have a couple of nuances: visibility: do you guarantee that all the writes methods of object o made are visible to the finalizer (i.e., there is a happens-before relationship between the last action on object o and the code performing finalization)? reachability: how do … Read more
The official documentation covers this. To override finalize(), all you need to do is simply declare it, without using the override keyword: class C { protected fun finalize() { // finalization logic } }
A couple of ideas considering your recent edits, although I agree it is a bit shooting in the dark… I would use a tool like “Beyond Compare” to compare the .Net Framework files and XML files on both machines (“folder compare” profile). Favour the binary level comparison to be perfectly sure… if both of your … Read more
This has changed in Xcode 4. Now Apps can be exported from the “Organizer” If you haven’t already, you need to create an Archive. On the menu go to Product -> Archive Once you’re in the Organizer – Archives screen click Share or Distribute… (Xcode 4.3.3 or newer) Then choose the format you want to … Read more
Answer E is correct answer. If E is not there, you will soon run out of memory (or) No correct answer. Object should be unreachable to be eligible for GC. JVM will do multiple scans and moving objects from one generation to another generation to determine the eligibility of GC and frees the memory when … Read more
final final can be used to mark a variable “unchangeable” private final String name = “foo”; //the reference name can never change final can also make a method not “overrideable” public final String toString() { return “NULL”; } final can also make a class not “inheritable”. i.e. the class can not be subclassed. public final … Read more
