Transient variables are not serialized, so they are not transmitted over the network during serialization.
Transient variables are marked with the 'transient' keyword in Java.
They are excluded from the serialization process, meaning their values are not saved.
Example: If a class has a transient variable 'password', it won't be serialized.
When the object is deserialized, transient variables will have their default v...
