Question

What does it mean: The serializable class does not declare a static final serialVersionUID field?

The serializable class VaadintestprojectApplication does not declare a static final serialVersionUID field of type long

What does this statement mean? I get an error for this.
What does serizlizable class do and why do we need to declare a static final for it.

1. It not an error, its a warning. 2. If you don't know what the Serializable *interface* does, why are you using it? — Peter Lawrey, Dec 31 '10 at 09:07

You should take a look at Serializable javadoc, which explains this far better than any StackOverflow contributor.
