Before explaining the use of finalize (), there are a few points to be set about the Java garbage collector: "Object can not be garbage collected": Java garbage collection follows a feature, that is, can not be recycled without recycling.

From: http://www.cnblogs.com/lzhdim/archive/2009/11/04/1595845.html   Before learning about finalize and dispose, we need to understand two concepts: managed resources and non-commissioned resources.A. managed resources generally refer to the memory

The last post talked about the optimization of the garbage collector. After a long time, I didn't continue to talk about finalize (in fact, this is a bit of a problem with GC ). Today, let's take a look at the performance topics related to finalize

1. The role of Finalize Finalize () is the protected method of object, which can be overridden by subclasses to implement resource cleanup, which is called by the GC before it reclaims the object. Finalize () does not correspond to

This is the best article I have read about finalize in Java. Finalize () in Java () When the garbage collector wants to recycle objects, it first needs to call the Finalize method of this class (you can write a program to verify this conclusion).

Finalfinal-modifier (keyword) If a class is declared final, it means that it can no longer derive a new subclass and cannot be inherited as a parent class. Therefore, a class cannot be declared abstract and declared final. Declaring variables or

Function Understanding Finalize ()-destructor substitution In many ways, Java is similar to C + +. Java syntax is very similar to C++,java classes, methods, and data members; Java classes have constructors; Java has exception handling.

The following are the descriptions in the JDK:Called by the garbage collector on a object when garbage collection determines that there is no more references to the O Bject. A Subclass overrides the finalize method to dispose of the system resources

Basic Preparation related knowledge1 Java GC is only responsible for memory-related cleanup, and all other resource cleanup must be done manually by the programmer. Otherwise, it can cause a resource leak, which could cause the program to crash.2

Programmers are aware of the importance of initialization, but often forget the same important cleanup effort. After all, who needs to clear an int? However, when using a library, it is not always safe to "discard" an object after it has been
