An excerpt of chapter 9, Garbage Collection, of Bill Venners' book Inside the Java Virtual Machine.
garbage collector when you hold soft, weak, or phantom references, you can arrange to be notified when such changes occur. To register interest in reachability state changes, you associate reference objects with reference queues. Areference queueis an instance of classjava.lang.ref.ReferenceQueueto...
I have a theory as to why this is: when older developers who got started in C/C++ started to try out garbage collected languages like C# and Java, we were initially very suspicious. Freeing memory was such a critical part of how we were used to writing code, that we wanted to know e...

Java, on the other hand, adopts a different approach by providing automatic Garbage Collection (GC) as part of its memory management strategy. The Garbage Collector automatically identifies and reclaims unused memory, freeing the programmer from manual memory management tasks. This automatic memory man...
should be garbage collected at the end. Note it also occurs if I break the query up into lots of queries (e.g., one query per user). I was considering filing this as a bug, but it is right in that grey area-- pilot error, overly aggressive garbage collection by Java, or ...
You can overwrite the array with any value of your choosing, ensuring that the password will not exist anywhere in the system, even prior to garbage collection.Java itself advises the use of the getPassword() method of JPasswordField, which returns a char[], while deprecating the getText() ...
1. The finalize() in Java 1.1. Syntax It is called by the garbage collector on an object when garbage collection determines that there are no more references to the object. A subclass overrides the finalize() method to dispose of system resources or to perform other cleanups. Notice that fi...
(or at least frighteningly inefficient) to those raised on JavaBeans—but remember that almost every release of the JDK improves performance. The engineers who advance the JDK work particularly hard on fast object creation and garbage collection. The result is that creation and re-creation, ...
