What Happens When A Class Does Not Define Serialversionuid In Java?

1.	What Happens When A Class Does Not Define Serialversionuid In Java?
Answer» If the serialVersionUID is not defined, then after any modification made in class, we won?t be able to DESERIALIZE existing objects for same class because serialVersionUID GENERATED by Java compiler for the modified class will be different from the old serialized OBJECT. Deserialization process will fail by throwing java.io.Invalid Class Exception. If the serialVersionUID is not defined, then after any modification made in class, we won?t be able to deSerialize existing objects for same class because serialVersionUID generated by Java compiler for the modified class will be different from the old serialized object. Deserialization process will fail by throwing java.io.Invalid Class Exception.
