Sometimes whenever I write any code in Wsad, I get this message at the side of my code.
The Serializable class xyz does not declare a static final serialversionUID field of type long and gives me an option to add a default serial version id. now, when I click on the option, a new line is added to my code as follows: private static final long serialVersionUID = 1L;
and I don't know what all this means. Anybody has any idea?
