My understanding is that JVM looking for specific signatures for the

I don't understand this statement.




hence interfaces like Serializable, Clonable have a specific meaning
to the jvm.




A marker interface, like Serializable or Cloneable may have a specific
meaning to a Java Virtual Machine, or to a Java compiler, or to another
Java class.



In the particular case of deserializing a serialized Java object the
meaning of the Serializable interface to a JVM is that it is possible
that it can proceed to reconstruct that serialized object according to
the Java Object Serialization Specification.
^
when called upon to do so



What would a Java compiler do with the knowledge that a class implements
the java.io.Serializable interface?



What classes in the Java standard library could make use of the
knowledge that another class implements the java.io.Serializable
interface, and what could they do with this knowledge?




so, its roughly like an IoC principle: "Instead of I define myself,
you define me".




I don't understand this statement.




Am I correct ?
