Setting serialVersionUID

[Robert Hill]

On the warning about a serialiable class not having an id, Eclipse offers 3 quick fixes:

Add default serial version ID
Add generated serial version ID
Add @SuppressWarnings to class

Of the first 2, is one always better, if not when is one better?

About the last option, it seems wrong to me to ignore any warning. Ia this not the case?

None of these three is "better" -- each has an appropriate use. The third one is perfectly appropriate if you choose not to worry about versioning for the class -- i.e., if the serialized data will never be stored in a file or shared with some other revision of this same program. Otherwise the first one is perfectly fine; I can't imagine any situation where the second one would be preferable, but it's also not worse in any way.
