Difference Betwixt Serializable As Well As Externalizable Inwards Coffee Serialization
Difference betwixt serializable too externalizable is popular coffee interview question which nosotros direct keep touched on my before postal service on Serialization: Top 10 coffee serialization interview questions. knowing differences betwixt externalizable too serializable is non only of import from interview indicate of thought but likewise getting command of serialization process and optimizing functioning of serialization. both serializable too extenalizable used to serialize or persist coffee objects but the agency they produce is little different. In instance of Serializable Java Virtual machine has total control for serializing object piece inward instance of Externalizable, application gets command for persisting objects. writeExternal() too readExternal() method provides consummate control on format too content of Serialization process to application which tin give the axe live on leverage to increase functioning too speed of serialization process.

3. Externalizable interface provides consummate command of serialization procedure to application.
4. readExternal() too writeExternal() replace whatever specific implementation of writeObject too readObject methods.
