ObjectOutputStream is not using the old serialization stream format (set by calling ObjectOutputStream'suseProtocolVersionmethod). If this serialization stream is using the old format (PROTOCOL_VERSION_1), the class descriptor will be written internally in a manner that cannot be overridden or ...
Most object-oriented applications do not allow other objects to access their fields directly by declaring them private. Then they make their methods protected, public, or package as needed and allow other objects to manipulate their private data by calling the methods only. This way, you can upd...

The returned value may or may not be identical toname. Calling this method twice with the same parameters may return the same object or two equal but not identical objects. Since ObjectName is immutable, it is not usually useful to make a copy of an ObjectName. The principal use of this...
