i was reading an article today and it said it is important to give serialVersionUID variable to your class which we think will be required to serialize. My question are given below
1.) what will be the problem we will face if we do not give serialVersionUID in our serialized
java class (i know java will create one for us if we dont give but what is the actual significance)
2.) I got to know that serialVersionUID should be unique in our class and there is a
serialVer utility from java which create a unique number for every class. now my question is i give every serialized class the same serialVersionUID, what problems we will face during serialization and de-serialization process.
