How should I declare fields within my serializable class to prevent them from being serialized?

(Static fields are not serialized anyway) Java 2 provides you with another mechanism for specifying which fields need to be serialized. Your class can declare the static field: public final ObjectStreamField[] serialPersistentFields = {…}; initialized with instances of ObjectStreamField, within each instance indicating the name and type of the serializable field. For example: public class FooBar implements Serialzable { private Foo foo; private int bar; private String passwd; public final static ObjectStreamField[] serialPersistentFields = { new ObjectStreamField(“foo”,Foo.class), new ObjectStreamField(“bar”,Integer.TYPE) }; } indicates that only the fields foo and bar must be serialized.
