The DVE, created using Java, is intended to allow for the creation of applications to enable multiple users to collaboratively interact in, and communicate about, a virtual world. This DVE is used to primarily support a flight simulator application. Three client-server synchronization methods were ...
There are several classes in thejava.util.concurrent.atomicpackage that use efficient machine-level instructions to guarantee the atomicity of other operations without using locks. For example, theAtomicIntegerclass has methodsincrementAndGetanddecrementAndGetthat atomically increment or decrement an integer. ...
mutable objects passed to the constructor; if necessary, create copies, and store references to the copies. Similarly, create copies of your internal mutable objects when necessary to avoid returning the originals in your methods.
Unlike synchronized methods, synchronized statements must specify the object that provides the intrinsic lock: public void addName(String name) { synchronized(this) { lastName = name; nameCount++; } nameList.add(name); } In this example, the addName method needs to synchronize changes to ...
Synchronized methods in Java put a performance cost on your application. So use synchronization when it is absolutely required. Also, consider using synchronized code blocks for synchronizing only critical section of your code. It’s possible that both static synchronized and non static synchronized me...

Here, for better concurrency, we’ve granularized the locking scheme by defining multipleprivate finallock objects to separate our synchronization concerns for both of the methods –setNameandsetOwner. Additionally, if a method that implements thesynchronizedblock modifies astaticvariable, we must synch...

java -cp .;osync_se.jar oracle.opensync.tools.SetParam OSE.FILES=NO You can invoke the utility in command line or call the included class methods in oracle.opensync.tools.SetParam from your own classes to programmatically set the parameters in ose.ini before the call to sync. ...
The synchronized methods prevent more than one thread from accessing an object's critical method code simultaneously. You can use the synchronized keyword as a method modifier, or to start a synchronized block of code. To synchronize a block of code (in other words, a scope smaller than the ...
