is there any upper limit in JVM that it can hold Objects and also can i be able to do say i have an object and i want that object to be shared with another jvm running on a different machine.if i can share then is there any upper limit for that. as it is a general rule that every application or anything it might be has a lower and upper bound above which it cannot.
Java itself does not place a limit on the number of objects, but individual JVM implementations do, explicitly or implicitly. It is fairly unlikely that you'd hit this limit, as you'd almost always run out of memory sooner.
Objects cannot be shared between JVMs directly. However, there are lots of ways of obtaining the effect of sharing. Look up RMI, CORBA, SOAP etc.
Betty Rubble? Well, I would go with Betty... but I'd be thinking of Wilma.
