For the shallow copy approach, we only copy field values, therefore the copy might be dependant on the original object. In the deep copy approach, we make sure that all the objects in the tree are deeply copied, so the copy isn’t dependant on any earlier existing object that might ever...
The method defineClass converts an array of bytes into an instance of class Class. Instances of this newly defined class can be created using Class.newInstance. The methods and constructors of objects created by a class loader may reference other classes. To determine the class(es) referred ...

real reference. The inability to relocate objects causes object memory fragmentation and, more importantly, prevents use of the advanced generational copying collection algorithms described below. Because the Java HotSpot collector is fully accurate, it can make several strong design guarantees that a ...
