The members of the class should be serializable. If one or more of the members are not to be serialized, they should be marked as transient. If a serializable class does not explicitly declare a serialVersionUID, then the serialization runtime will calculate a default serialVersionUID value for that class based on various aspects of the class, as described in the Java Object Serialization Specification.

When we use Java Serialization to serialize or deserialize an object, its class and non-static fields must be all serializable. Otherwise, it will lead to NotSerializableException.

The type checking knows that set is not serializable, but a subtype of set can be serializable. Set is a Interface. But implementation of set is HashSet. This is serializable. You would not expect to serialize a Set because a Set can not be instantiated. Set st = new Set(); // illegal So set doesn't really need to implement Serializable.
