What is the need to implement Serializable interface (with
no methods) for objects which are to be serialized ?
We can write our own functionality which writes objects to
streams then why we need to implement and tell JVM that
which objects can be serialized.

Ya that answers are expected but...
If we open ObjectOutputStream.java (which is used for
serialization) then we see the following code :
............................
writeObject0(Object obj, boolean unshared){
.............
} else if (cl.isArray()) {
writeArray(obj, desc, unshared);
} else if (obj instanceof Serializable) {
writeOrdinaryObject(obj, desc, unshared);
} else {
throw new NotSerializableException(cl.getName());
}
................
If we remove the checking instanceof (& recompile) or if we
override the writeObject0 method then
Will it still check whethere the class has implemented
serilizable ?
